Obesity is a chronic health condition in which the body fat reaches abnormal level. Obesity occurs when we consume much more amount of food than our body really needs on a daily basis. In other words, when the intake of calories is greater than the calories we burn out, it gives rise to obesity.

Audience: The below given essays are exclusively written for school students (Class 5, 6, 7, 8, 9, 10, 11 and 12 Standard), college, science and medical students.

Introduction:

Obesity means being excessively fat. A person would be said to be obese if his or her body mass index is beyond 30. Such a person has a body fat rate that is disproportionate to his body mass.

Obesity and the Body Mass Index:

The body mass index is calculated considering the weight and height of a person. Thus, it is a scientific way of determining the appropriate weight of any person. When the body mass index of a person indicates that he or she is obese, it exposes the person to make health risk.

Stopping Obesity:

There are two major ways to get the body mass index of a person to a moderate rate. The first is to maintain a strict diet. The second is to engage in regular physical exercise. These two approaches are aimed at reducing the amount of fat in the body.

Conclusion:

Obesity can lead to sudden death, heart attack, diabetes and may unwanted illnesses. Stop it by making healthy choices.

Obesity has become a big concern for the youth of today’s generation. Obesity is defined as a medical condition in which an individual gains excessive body fat. When the Body Mass Index (BMI) of a person is over 30, he/ she is termed as obese.

Obesity can be a genetic problem or a disorder that is caused due to unhealthy lifestyle habits of a person. Physical inactivity and the environment in which an individual lives, are also the factors that leads to obesity. It is also seen that when some individuals are in stress or depression, they start cultivating unhealthy eating habits which eventually leads to obesity. Medications like steroids is yet another reason for obesity.

Obesity has several serious health issues associated with it. Some of the impacts of obesity are diabetes, increase of cholesterol level, high blood pressure, etc. Social impacts of obesity includes loss of confidence in an individual, lowering of self-esteem, etc.

The risks of obesity needs to be prevented. This can be done by adopting healthy eating habits, doing some physical exercise regularly, avoiding stress, etc. Individuals should work on weight reduction in order to avoid obesity.

Obesity is indeed a health concern and needs to be prioritized. The management of obesity revolves around healthy eating habits and physical activity. Obesity, if not controlled in its initial stage can cause many severe health issues. So it is wiser to exercise daily and maintain a healthy lifestyle rather than being the victim of obesity.

Obesity can be defined as the clinical condition where accumulation of excessive fat takes place in the adipose tissue leading to worsening of health condition. Usually, the fat is deposited around the trunk and also the waist of the body or even around the periphery.

Obesity is actually a disease that has been spreading far and wide. It is preventable and certain measures are to be taken to curb it to a greater extend. Both in the developing and developed countries, obesity has been growing far and wide affecting the young and the old equally.

The alarming increase in obesity has resulted in stimulated death rate and health issues among the people. There are several methods adopted to lose weight and they include different diet types, physical activity and certain changes in the current lifestyle. Many of the companies are into minting money with the concept of inviting people to fight obesity.

In patients associated with increased risk factor related to obesity, there are certain drug therapies and other procedures adopted to lose weight. There are certain cost effective ways introduced by several companies to enable clinic-based weight loss programs.

Obesity can lead to premature death and even cause Type 2 Diabetes Mellitus. Cardiovascular diseases have also become the part and parcel of obese people. It includes stroke, hypertension, gall bladder disease, coronary heart disease and even cancers like breast cancer, prostate cancer, endometrial cancer and colon cancer. Other less severe arising due to obesity includes osteoarthritis, gastro-esophageal reflux disease and even infertility.

Hence, serious measures are to be taken to fight against this dreadful phenomenon that is spreading its wings far and wide. Giving proper education on benefits of staying fit and mindful eating is as important as curbing this issue. Utmost importance must be given to healthy eating habits right from the small age so that they follow the same until the end of their life.

Obesity is majorly a lifestyle disease attributed to the extra accumulation of fat in the body leading to negative health effects on a person. Ironically, although prevalent at a large scale in many countries, including India, it is one of the most neglect health problems. It is more often ignored even if told by the doctor that the person is obese. Only when people start acquiring other health issues such as heart disease, blood pressure or diabetes, they start taking the problem of obesity seriously.

Obesity Statistics in India:

As per a report, India happens to figure as the third country in the world with the most obese people. This should be a troubling fact for India. However, we are yet to see concrete measures being adopted by the people to remain fit.

Causes of Obesity:

Sedentary lifestyle, alcohol, junk food, medications and some diseases such as hypothyroidism are considered as the factors which lead to obesity. Even children seem to be glued to televisions, laptops and video games which have taken away the urge for physical activities from them. Adding to this, the consumption of junk food has further aggravated the growing problem of obesity in children.

In the case of adults, most of the professions of today make use of computers which again makes people sit for long hours in one place. Also, the hectic lifestyle of today makes it difficult for people to spare time for physical activities and people usually remain stressed most of the times. All this has contributed significantly to the rise of obesity in India.

Obesity and BMI:

Body Mass Index (BMI) is the measure which allows a person to calculate how to fit he or she is. In other words, the BMI tells you if you are obese or not. BMI is calculated by dividing the weight of a person in kg with the square of his / her height in metres. The number thus obtained is called the BMI. A BMI of less than 25 is considered optimal. However, if a person has a BMI over 30 he/she is termed as obese.

What is a matter of concern is that with growing urbanisation there has been a rapid increase of obese people in India? It is of utmost importance to consider this health issue a serious threat to the future of our country as a healthy body is important for a healthy soul. We should all be mindful of what we eat and what effect it has on our body. It is our utmost duty to educate not just ourselves but others as well about this serious health hazard.

Obesity can be defined as a condition (medical) that is the accumulation of body fat to an extent that the excess fat begins to have a lot of negative effects on the health of the individual. Obesity is determined by examining the body mass index (BMI) of the person. The BMI is gotten by dividing the weight of the person in kilogram by the height of the person squared.

When the BMI of a person is more than 30, the person is classified as being obese, when the BMI falls between 25 and 30, the person is said to be overweight. In a few countries in East Asia, lower values for the BMI are used. Obesity has been proven to influence the likelihood and risk of many conditions and disease, most especially diabetes of type 2, cardiovascular diseases, sleeplessness that is obstructive, depression, osteoarthritis and some cancer types.

In most cases, obesity is caused through a combination of genetic susceptibility, a lack of or inadequate physical activity, excessive intake of food. Some cases of obesity are primarily caused by mental disorder, medications, endocrine disorders or genes. There is no medical data to support the fact that people suffering from obesity eat very little but gain a lot of weight because of slower metabolism. It has been discovered that an obese person usually expends much more energy than other people as a result of the required energy that is needed to maintain a body mass that is increased.

It is very possible to prevent obesity with a combination of personal choices and social changes. The major treatments are exercising and a change in diet. We can improve the quality of our diet by reducing our consumption of foods that are energy-dense like those that are high in sugars or fat and by trying to increase our dietary fibre intake.

We can also accompany the appropriate diet with the use of medications to help in reducing appetite and decreasing the absorption of fat. If medication, exercise and diet are not yielding any positive results, surgery or gastric balloon can also be carried out to decrease the volume of the stomach and also reduce the intestines’ length which leads to the feel of the person get full early or a reduction in the ability to get and absorb different nutrients from a food.

Obesity is the leading cause of ill-health and death all over the world that is preventable. The rate of obesity in children and adults has drastically increased. In 2015, a whopping 12 percent of adults which is about 600 million and about 100 million children all around the world were found to be obese.

It has also been discovered that women are more obese than men. A lot of government and private institutions and bodies have stated that obesity is top of the list of the most difficult and serious problems of public health that we have in the world today. In the world we live today, there is a lot of stigmatisation of obese people.

We all know how troubling the problem of obesity truly is. It is mainly a form of a medical condition wherein the body tends to accumulate excessive fat which in turn has negative repercussions on the health of an individual.

Given the current lifestyle and dietary style, it has become more common than ever. More and more people are being diagnosed with obesity. Such is its prevalence that it has been termed as an epidemic in the USA. Those who suffer from obesity are at a much higher risk of diabetes, heart diseases and even cancer.

In order to gain a deeper understanding of obesity, it is important to learn what the key causes of obesity are. In a layman term, if your calorie consumption exceeds what you burn because of daily activities and exercises, it is likely to lead to obesity. It is caused over a prolonged period of time when your calorie intake keeps exceeding the calories burned.

Here are some of the key causes which are known to be the driving factors for obesity.

If your diet tends to be rich in fat and contains massive calorie intake, you are all set to suffer from obesity.

Sedentary Lifestyle:

With most people sticking to their desk jobs and living a sedentary lifestyle, the body tends to get obese easily.

Of course, the genetic framework has a lot to do with obesity. If your parents are obese, the chance of you being obese is quite high.

The weight which women gain during their pregnancy can be very hard to shed and this is often one of the top causes of obesity.

Sleep Cycle:

If you are not getting an adequate amount of sleep, it can have an impact on the hormones which might trigger hunger signals. Overall, these linked events tend to make you obese.

Hormonal Disorder:

There are several hormonal changes which are known to be direct causes of obesity. The imbalance of the thyroid stimulating hormone, for instance, is one of the key factors when it comes to obesity.

Now that we know the key causes, let us look at the possible ways by which you can handle it.

Treatment for Obesity:

As strange as it may sound, the treatment for obesity is really simple. All you need to do is follow the right diet and back it with an adequate amount of exercise. If you can succeed in doing so, it will give you the perfect head-start into your journey of getting in shape and bidding goodbye to obesity.

There are a lot of different kinds and styles of diet plans for obesity which are available. You can choose the one which you deem fit. We recommend not opting for crash dieting as it is known to have several repercussions and can make your body terribly weak.

The key here is to stick to a balanced diet which can help you retain the essential nutrients, minerals, and, vitamins and shed the unwanted fat and carbs.

Just like the diet, there are several workout plans for obesity which are available. It is upon you to find out which of the workout plan seems to be apt for you. Choose cardio exercises and dance routines like Zumba to shed the unwanted body weight. Yoga is yet another method to get rid of obesity.

So, follow a blend of these and you will be able to deal with the trouble of obesity in no time. We believe that following these tips will help you get rid of obesity and stay in shape.

Obesity and overweight is a top health concern in the world due to the impact it has on the lives of individuals. Obesity is defined as a condition in which an individual has excessive body fat and is measured using the body mass index (BMI) such that, when an individual’s BMI is above 30, he or she is termed obese. The BMI is calculated using body weight and height and it is different for all individuals.

Obesity has been determined as a risk factor for many diseases. It results from dietary habits, genetics, and lifestyle habits including physical inactivity. Obesity can be prevented so that individuals do not end up having serious complications and health problems. Chronic illnesses like diabetes, heart diseases and relate to obesity in terms of causes and complications.

Factors Influencing Obesity:

Obesity is not only as a result of lifestyle habits as most people put it. There are other important factors that influence obesity. Genetics is one of those factors. A person could be born with genes that predispose them to obesity and they will also have difficulty in losing weight because it is an inborn factor.

The environment also influences obesity because the diet is similar in certain environs. In certain environments, like school, the food available is fast foods and the chances of getting healthy foods is very low, leading to obesity. Also, physical inactivity is an environmental factor for obesity because some places have no fields or tracks where people can jog or maybe the place is very unsafe and people rarely go out to exercise.

Mental health affects the eating habits of individuals. There is a habit of stress eating when a person is depressed and it could result in overweight or obesity if the person remains unhealthy for long period of time.

The overall health of individuals also matter. If a person is unwell and is prescribed with steroids, they may end up being obese. Steroidal medications enable weight gain as a side effect.

Complications of Obesity:

Obesity is a health concern because its complications are severe. Significant social and health problems are experienced by obese people. Socially, they will be bullied and their self-esteem will be low as they will perceive themselves as unworthy.

Chronic illnesses like diabetes results from obesity. Diabetes type 2 has been directly linked to obesity. This condition involves the increased blood sugars in the body and body cells are not responding to insulin as they should. The insulin in the body could also be inadequate due to decreased production. High blood sugar concentrations result in symptoms like frequent hunger, thirst and urination. The symptoms of complicated stages of diabetes type 2 include loss of vision, renal failure and heart failure and eventually death. The importance of having a normal BMI is the ability of the body to control blood sugars.

Another complication is the heightened blood pressures. Obesity has been defined as excessive body fat. The body fat accumulates in blood vessels making them narrow. Narrow blood vessels cause the blood pressures to rise. Increased blood pressure causes the heart to start failing in its physiological functions. Heart failure is the end result in this condition of increased blood pressures.

There is a significant increase in cholesterol in blood of people who are obese. High blood cholesterol levels causes the deposition of fats in various parts of the body and organs. Deposition of fats in the heart and blood vessels result in heart diseases. There are other conditions that result from hypercholesterolemia.

Other chronic illnesses like cancer can also arise from obesity because inflammation of body cells and tissues occurs in order to store fats in obese people. This could result in abnormal growths and alteration of cell morphology. The abnormal growths could be cancerous.

Management of Obesity:

For the people at risk of developing obesity, prevention methods can be implemented. Prevention included a healthy diet and physical activity. The diet and physical activity patterns should be regular and realizable to avoid strains that could result in complications.

Some risk factors for obesity are non-modifiable for example genetics. When a person in genetically predisposed, the lifestyle modifications may be have help.

For the individuals who are already obese, they can work on weight reduction through healthy diets and physical exercises.

In conclusion, obesity is indeed a major health concern because the health complications are very serious. Factors influencing obesity are both modifiable and non-modifiable. The management of obesity revolves around diet and physical activity and so it is important to remain fit.

In olden days, obesity used to affect only adults. However, in the present time, obesity has become a worldwide problem that hits the kids as well. Let’s find out the most prevalent causes of obesity.

Factors Causing Obesity:

Obesity can be due to genetic factors. If a person’s family has a history of obesity, chances are high that he/ she would also be affected by obesity, sooner or later in life.

The second reason is having a poor lifestyle. Now, there are a variety of factors that fall under the category of poor lifestyle. An excessive diet, i.e., eating more than you need is a definite way to attain the stage of obesity. Needless to say, the extra calories are changed into fat and cause obesity.

Junk foods, fried foods, refined foods with high fats and sugar are also responsible for causing obesity in both adults and kids. Lack of physical activity prevents the burning of extra calories, again, leading us all to the path of obesity.

But sometimes, there may also be some indirect causes of obesity. The secondary reasons could be related to our mental and psychological health. Depression, anxiety, stress, and emotional troubles are well-known factors of obesity.

Physical ailments such as hypothyroidism, ovarian cysts, and diabetes often complicate the physical condition and play a massive role in abnormal weight gain.

Moreover, certain medications, such as steroids, antidepressants, and contraceptive pills, have been seen interfering with the metabolic activities of the body. As a result, the long-term use of such drugs can cause obesity. Adding to that, regular consumption of alcohol and smoking are also connected to the condition of obesity.

Harmful Effects of Obesity:

On the surface, obesity may look like a single problem. But, in reality, it is the mother of several major health issues. Obesity simply means excessive fat depositing into our body including the arteries. The drastic consequence of such high cholesterol levels shows up in the form of heart attacks and other life-threatening cardiac troubles.

The fat deposition also hampers the elasticity of the arteries. That means obesity can cause havoc in our body by altering the blood pressure to an abnormal range. And this is just the tip of the iceberg. Obesity is known to create an endless list of problems.

In extreme cases, this disorder gives birth to acute diseases like diabetes and cancer. The weight gain due to obesity puts a lot of pressure on the bones of the body, especially of the legs. This, in turn, makes our bones weak and disturbs their smooth movement. A person suffering from obesity also has higher chances of developing infertility issues and sleep troubles.

Many obese people are seen to be struggling with breathing problems too. In the chronic form, the condition can grow into asthma. The psychological effects of obesity are another serious topic. You can say that obesity and depression form a loop. The more a person is obese, the worse is his/ her depression stage.

How to Control and Treat Obesity:

The simplest and most effective way, to begin with, is changing our diet. There are two factors to consider in the diet plan. First is what and what not to eat. Second is how much to eat.

If you really want to get rid of obesity, include more and more green vegetables in your diet. Spinach, beans, kale, broccoli, cauliflower, asparagus, etc., have enough vitamins and minerals and quite low calories. Other healthier options are mushrooms, pumpkin, beetroots, and sweet potatoes, etc.

Opt for fresh fruits, especially citrus fruits, and berries. Oranges, grapes, pomegranate, pineapple, cherries, strawberries, lime, and cranberries are good for the body. They have low sugar content and are also helpful in strengthening our immune system. Eating the whole fruits is a more preferable way in comparison to gulping the fruit juices. Fruits, when eaten whole, have more fibers and less sugar.

Consuming a big bowl of salad is also great for dealing with the obesity problem. A salad that includes fibrous foods such as carrots, radish, lettuce, tomatoes, works better at satiating the hunger pangs without the risk of weight gain.

A high protein diet of eggs, fish, lean meats, etc., is an excellent choice to get rid of obesity. Take enough of omega fatty acids. Remember to drink plenty of water. Keeping yourself hydrated is a smart way to avoid overeating. Water also helps in removing the toxins and excess fat from the body.

As much as possible, avoid fats, sugars, refined flours, and oily foods to keep the weight in control. Control your portion size. Replace the three heavy meals with small and frequent meals during the day. Snacking on sugarless smoothies, dry fruits, etc., is much recommended.

Regular exercise plays an indispensable role in tackling the obesity problem. Whenever possible, walk to the market, take stairs instead of a lift. Physical activity can be in any other form. It could be a favorite hobby like swimming, cycling, lawn tennis, or light jogging.

Meditation and yoga are quite powerful practices to drive away the stress, depression and thus, obesity. But in more serious cases, meeting a physician is the most appropriate strategy. Sometimes, the right medicines and surgical procedures are necessary to control the health condition.

Obesity is spreading like an epidemic, haunting both the adults and the kids. Although genetic factors and other physical ailments play a role, the problem is mostly caused by a reckless lifestyle.

By changing our way of living, we can surely take control of our health. In other words, it would be possible to eliminate the condition of obesity from our lives completely by leading a healthy lifestyle.

Obesity: Risk factors, complications, and strategies for sustainable long‐term weight management

Sharon m. fruh.

1 College of Nursing, University of South Alabama, Mobile, Alabama

Background and Purpose

The aims of this article are to review the effects of obesity on health and well‐being and the evidence indicating they can be ameliorated by weight loss, and consider weight‐management strategies that may help patients achieve and maintain weight loss.

Narrative review based on literature searches of PubMed up to May 2016 with no date limits imposed. Search included terms such as “obesity,” “overweight,” “weight loss,” “comorbidity,” “diabetes,” cardiovascular,” “cancer,” “depression,” “management,” and “intervention.”

Conclusions

Over one third of U.S. adults have obesity. Obesity is associated with a range of comorbidities, including diabetes, cardiovascular disease, obstructive sleep apnea, and cancer; however, modest weight loss in the 5%–10% range, and above, can significantly improve health‐related outcomes. Many individuals struggle to maintain weight loss, although strategies such as realistic goal‐setting and increased consultation frequency can greatly improve the success of weight‐management programs. Nurse practitioners have key roles in establishing weight‐loss targets, providing motivation and support, and implementing weight‐loss programs.

Implications for Practice

With their in‐depth understanding of the research in the field of obesity and weight management, nurse practitioners are well placed to effect meaningful changes in weight‐management strategies deployed in clinical practice.

Introduction

Obesity is an increasing, global public health issue. Patients with obesity are at major risk for developing a range of comorbid conditions, including cardiovascular disease (CVD), gastrointestinal disorders, type 2 diabetes (T2D), joint and muscular disorders, respiratory problems, and psychological issues, which may significantly affect their daily lives as well as increasing mortality risks. Obesity‐associated conditions are manifold; however, even modest weight reduction may enable patients to reduce their risk for CVD, diabetes, obstructive sleep apnea (OSA), and hypertension among many other comorbidities (Cefalu et al., 2015 ). A relatively small and simple reduction in weight, for example, of around 5%, can improve patient outcomes and may act as a catalyst for further change, with sustainable weight loss achieved through a series of incremental weight loss steps. In facilitating the process of losing weight for patients, nurse practitioners play an essential role. Through assessing the patient's risk, establishing realistic weight‐loss targets, providing motivation and support, and supplying patients with the necessary knowledge and treatment tools to help achieve weight loss, followed by tools for structured lifestyle support to maintain weight lost, the nurse practitioner is ideally positioned to help patient's achieve their weight‐loss—and overall health—targets.

The obesity epidemic

The World Health Organization (WHO) defines overweight and obesity as abnormal or excessive fat accumulation that presents a risk to health (WHO, 2016a ). A body mass index (BMI) ≥25 kg/m 2 is generally considered overweight, while obesity is considered to be a BMI ≥ 30 kg/m 2 . It is well known that obesity and overweight are a growing problem globally with high rates in both developed and developing countries (Capodaglio & Liuzzi, 2013 ; WHO, 2016a , 2016b ).

In the United States in 2015, all states had an obesity prevalence more than 20%, 25 states and Guam had obesity rates >30% and four of those 25 states (Alabama, Louisiana, Mississippi, and West Virginia) had rates >35% (Centres for Disease Control and Prevention, 2016 ; Figure ​ Figure1). 1 ). Approximately 35% and 37% of adult men and women, respectively, in the United States have obesity (Yang & Colditz, 2015 ). Adult obesity is most common in non‐Hispanic black Americans, followed by Mexican Americans, and non‐Hispanic white Americans (Yang & Colditz, 2015 ). Individuals are also getting heavier at a younger age; birth cohorts from 1966 to 1975 and 1976 to 1985 reached an obesity prevalence of ≥20% by 20–29 years of age, while the 1956–1965 cohort only reached this prevalence by age 30–39 years (Lee et al., 2010 ). Additionally, the prevalence of childhood obesity in 2‐ to 17‐year‐olds in the United States has increased from 14.6% in 1999–2000 to 17.4% in 2013–2014 (Skinner & Skelton, 2014 ). Childhood obesity is an increasing health issue because of the early onset of comorbidities that have major adverse health impacts, and the increased likelihood of children with obesity going on to become adults with obesity (50% risk vs. 10% for children without obesity; Whitaker, Wright, Pepe, Seidel, & Dietz, 1997 ).

Association of obesity with mortality and comorbid disease

Obesity is associated with a significant increase in mortality, with a life expectancy decrease of 5–10 years (Berrington de Gonzalez et al., 2010 ; Kuk et al., 2011 ; Prospective Studies Collaboration et al., 2009 ). There is evidence to indicate that all‐cause, CVD‐associated, and cancer‐associated mortalities are significantly increased in individuals with obesity, specifically those at Stages 2 or 3 of the Edmonton Obesity Staging System (EOSS; Kuk et al., 2011 ; Figure ​ Figure2). 2 ). Mortality related to cancer is, however, also increased at Stage 1, when the physical symptoms of obesity are marginal (Figure ​ (Figure2). 2 ). Recently, a large‐scale meta‐analysis that included studies that had enrolled over 10 million individuals, indicated that, relative to the reference category of 22.5 to <25 kg/m 2 , the hazard ratio (HR) for all‐cause mortality rose sharply with increasing BMI (The Global BMI Mortality Collaboration, 2016 ). For a BMI of 25.0 to <30.0 kg/m 2 , the HR was 1.11 (95% confidence interval [CI] 1.10, 1.11), and this increased to 1.44 (1.41, 1.47), 1.92 (1.86, 1.98), and 2.71 (2.55, 2.86) for a BMI of 30.0 to <35.0, 35.0 to <40.0, and 40.0 to <60.0 kg/m 2 , respectively.

Comorbidities

Obesity is a chronic disease that is associated with a wide range of complications affecting many different aspects of physiology (Dobbins, Decorby, & Choi, 2013 ; Guh et al., 2009 ; Martin‐Rodriguez, Guillen‐Grima, Marti, & Brugos‐Larumbe, 2015 ; summarized in Table ​ Table1). 1 ). To examine these obesity‐related morbidities in detail is beyond the scope of this review and therefore only a brief overview of some of the key pathophysiological processes is included next.

Morbidities associated with obesity (Hamdy, 2016 ; Petry, Barry, Pietrzak, & Wagner, 2008 ; Pi‐Sunyer, 2009 ; Sakai et al., 2005 ; Smith, Hulsey, & Goodnight, 2008 ; Yosipovitch, DeVore, & Dawn, 2007 )

The progression from lean state to obesity brings with it a phenotypic change in adipose tissue and the development of chronic low‐grade inflammation (Wensveen, Valentic, Sestan, Turk Wensveen, & Polic, 2015 ). This is characterized by increased levels of circulating free‐fatty acids, soluble pro‐inflammatory factors (such as interleukin [IL] 1β, IL‐6, tumor necrosis factor [TNF] α, and monocyte chemoattractant protein [MCP] 1) and the activation and infiltration of immune cells into sites of inflammation (Hursting & Dunlap, 2012 ). Obesity is also usually allied to a specific dyslipidemia profile (atherogenic dyslipidemia) that includes small, dense low‐density lipoprotein (LDL) particles, decreased levels of high‐density lipoprotein (HDL) particles, and raised triglyceride levels (Musunuru, 2010 ). This chronic, low‐grade inflammation and dyslipidemia profile leads to vascular dysfunction, including atherosclerosis formation, and impaired fibrinolysis. These, in turn, increase the risk for CVD, including stroke and venous thromboembolism (Blokhin & Lentz, 2013 ).

The metabolic and cardiovascular aspects of obesity are closely linked. The chronic inflammatory state associated with obesity is established as a major contributing factor for insulin resistance, which itself is one of the key pathophysiologies of T2D (Johnson, Milner, & Makowski, 2012 ). Furthermore, central obesity defined by waist circumference is the essential component of the International Diabetes Federation (IDF) definition of the metabolic syndrome (raised triglycerides, reduced HDL cholesterol, raised blood pressure, and raised fasting plasma glucose; International Diabetes Federation, 2006 ).

Obesity is also closely associated with OSA. To start, a number of the conditions associated with obesity such as insulin resistance (Ip et al., 2002 ), systemic inflammation, and dyslipidemia are themselves closely associated with OSA, and concurrently, the obesity‐associated deposition of fat around the upper airway and thorax may affect lumen size and reduce chest compliance that contributes to OSA (Romero‐Corral, Caples, Lopez‐Jimenez, & Somers, 2010 ).

The development of certain cancers, including colorectal, pancreatic, kidney, endometrial, postmenopausal breast, and adenocarcinoma of the esophagus to name a few, have also been shown to be related to excess levels of fat and the metabolically active nature of this excess adipose tissue (Booth, Magnuson, Fouts, & Foster, 2015 ; Eheman et al., 2012 ). Cancers have shown to be impacted by the complex interactions between obesity‐related insulin resistance, hyperinsulinemia, sustained hyperglycemia, oxidative stress, inflammation, and the production of adipokines (Booth et al., 2015 ). The wide range of morbidities associated with obesity represents a significant clinical issue for individuals with obesity. However, as significant as this array of risk factors is for patient health, the risk factors can be positively modified with weight loss.

Obesity‐related morbidities in children and adolescents

As was referred to earlier, children and adolescents are becoming increasingly affected by obesity. This is particularly concerning because of the long‐term adverse consequences of early obesity. Obesity adversely affects the metabolic health of young people and can result in impaired glucose tolerance, T2D, and early‐onset metabolic syndrome (Pulgaron, 2013 ).There is also strong support in the literature for relationships between childhood obesity and asthma, poor dental health (caries), nonalcoholic fatty liver disease (NAFLD), and gastroesophageal reflux disease (GERD; Pulgaron, 2013 ). Obesity can also affect growth and sexual development and may delay puberty in boys and advance puberty in some girls (Burt Solorzano & McCartney, 2010 ). Childhood obesity is also associated with hyperandrogenism and polycystic ovary syndrome (PCOS) in girls (Burt Solorzano & McCartney, 2010 ). Additionally, obesity is associated with psychological problems in young people including attention deficit hyperactivity disorder (ADHD), anxiety, depression, poor self‐esteem, and problems with sleeping (Pulgaron, 2013 ).

Modest weight loss and its long‐term maintenance: Benefits and risks

Guidelines endorse weight‐loss targets of 5%–10% in individuals with obesity or overweight with associated comorbidities, as this has been shown to significantly improve health‐related outcomes for many obesity‐related comorbidities (Cefalu et al., 2015 ; Figure ​ Figure3), 3 ), including T2D prevention, and improvements in dyslipidemia, hyperglycemia, osteoarthritis, stress incontinence, GERD, hypertension, and PCOS. Further benefits may be evident with greater weight loss, particularly for dyslipidemia, hyperglycemia, and hypertension. For NAFLD and OSA, at least 10% weight loss is required to observe clinical improvements (Cefalu et al., 2015 ).

Importantly, the weight‐loss benefits in terms of comorbidities are also reflected in improved all‐cause mortality. A recent meta‐analysis of 15 studies demonstrated that relatively small amounts of weight loss, on average 5.5 kg in the treatment arm versus 0.2 kg with placebo from an average baseline BMI of 35 kg/m 2 , resulted in a substantial 15% reduction in all‐cause mortality (Kritchevsky et al., 2015 ).

Cardiovascular health

Weight loss is associated with beneficial changes in several cardiovascular risk markers, including dyslipidemia, pro‐inflammatory/pro‐thrombotic mediators, arterial stiffness, and hypertension (Dattilo & Kris‐Etherton, 1992 ; Dengo et al., 2010 ; Goldberg et al., 2014 ; Haffner et al., 2005 ; Ratner et al., 2005 ). Importantly, weight loss was found to reduce the risk for CVD mortality by 41% up to 23 years after the original weight‐loss intervention (Li et al., 2014 ; Figure ​ Figure4). 4 ). Evidence including the biological effects of obesity and weight loss, and the increased risk for stroke with obesity indicates that weight loss may be effective for primary‐ and secondary‐stroke prevention (Kernan, Inzucchi, Sawan, Macko, & Furie, 2013 ).

Type 2 diabetes

Three major long‐term studies, the Diabetes Prevention Program (DPP), the Diabetes Prevention Study (DPS), and the Da Qing IGT and Diabetes (Da Qing) study, have demonstrated that modest weight loss through short‐term lifestyle or pharmacologic interventions can reduce the risk for developing T2D by 58%, 58%, and 31%, respectively, in individuals with obesity and prediabetes (DPP Research Group et al., 2009 ; Pan et al., 1997 ; Tuomilehto et al., 2001 ). Long‐term benefits were maintained following the interventions; for example, in the DPP, the risk reduction of developing T2D versus placebo was 34% at 10 years and 27% at 15 years following the initial weight‐loss intervention (DPP Research Group, 2015 ; DPP Research Group et al., 2009 ). Weight loss increased the likelihood of individuals reverting from prediabetes to normoglycemia (DPP Research Group et al., 2009 ; Li et al., 2008 ; Lindstrom et al., 2003 , 2006 ; Tuomilehto et al., 2001 ), and also improved other aspects of glycemic control including fasting and postprandial glucose, and insulin sensitivity (Haufe et al., 2013 ; Li et al., 2008 ).

Sleep apnea

Data indicate that weight loss is beneficial, although not curative, in patients with obesity who experience OSA. Meta‐analyses of patients who underwent treatment with either intensive lifestyle intervention (Araghi et al., 2013 ) or bariatric surgery (Greenburg, Lettieri, & Eliasson, 2009 ) demonstrated improvements in apnea‐hypopnea index (AHI) following treatment. In the first of these meta‐analyses, in randomized controlled trials, lifestyle intervention lead to a mean reduction in BMI of 2.3 kg/m 2 , which was associated with a decrease in mean AHI of 6.0 events/h. As expected, weight loss was much higher in the second meta‐analysis that investigated the effect of bariatric surgery on measures of OSA, and this was associated with greater reductions in AHI; the mean BMI reduction of 17.9 kg/m 2 resulted in AHI events being reduced by a mean of 38.2 events/h. Once these improvements in AHI have occurred, they seem to persist for some time, irrespective of a certain degree of weight regain. In one study, an initial mean weight loss of 10.7 kg resulted in a persistent improvement in AHI over a 4‐year period despite weight regain of approximately 50% by Year 4 (Kuna et al., 2013 ).

Intentional weight loss of >9 kg reduced the risk for a range of cancers including breast, endometrium, and colon in the large‐scale Iowa Women's Health Study (Parker & Folsom, 2003 ). The overall reduction in the incidence rate of any cancer was 11% (relative risk, 0.89; 95% CI 0.79, 1.00) for participants who lost more than 9 kg compared with those who did not achieve a more than 9 kg weight loss episode. Additionally, weight loss in participants with obesity has been established to be associated with reductions in cancer biomarkers including soluble E‐selectin and IL‐6 (Linkov et al., 2012 ).

Additional health benefits

The substantial weight loss associated with bariatric surgery has been shown to improve asthma with a 48%–100% improvement in symptoms and reduction in medication use (Juel, Ali, Nilas, & Ulrik, 2012 ); however, there is a potential threshold effect so that modest weight loss of 5%–10% may lead to clinical improvement (Lv, Xiao, & Ma, 2015 ). Similarly, modest weight loss of 5%–10% improves GERD (Singh et al., 2013 ) and liver function (Haufe et al., 2013 ). A study utilizing MRI scanning to examine the effects of weight loss on NAFLD has reported a reduction in liver fat from 18.3% to 13.6% ( p = .03), a relative reduction of 25% (Patel et al., 2015 ). Taking an active role in addressing obesity through behavioral modifications or exercise can also reduce the symptoms of depression (Fabricatore et al., 2011 ), improve urinary incontinence in men and women (Breyer et al., 2014 ; Brown et al., 2006 ), and improve fertility outcomes in women (Kort, Winget, Kim, & Lathi, 2014 ). Additionally, weight loss can reduce the joint‐pain symptoms and disability caused by weight‐related osteoarthritis (Felson, Zhang, Anthony, Naimark, & Anderson, 1992 ; Foy et al., 2011 ).

Mitigating risks

Despite the array of benefits, weight loss can also be linked with certain risks that may need to be managed. One such example is the risk for gallstones with rapid weight loss, which is associated with gallstone formation in 30%–71% of individuals. Gallstone formation is particularly associated with bariatric surgery when weight loss exceeds 1.5 kg/week and occurs particularly within the first 6 weeks following surgery when weight loss is greatest. Slower rates of weight loss appear to mitigate the risk for gallstone formation compared to the general population but may not eliminate it entirely; as was noted in the year‐long, weight‐loss, SCALE trial that compared liraglutide 3.0 mg daily use to placebo and resulted in gallstone formation in 2.5% of treated subjects compared to 1% of subjects taking placebo. For this reason, the risk for cholethiasis should be considered when formulating weight‐loss programs (Weinsier & Ullmann, 1993 ).

Strategies to help individuals achieve and maintain weight loss

Rogge and Gautam have covered the biology of obesity and weight regain within another section of this supplement (Rogge & Gautam, 2017 ), so here we focus on some of the clinical strategies for delivering weight loss and weight loss maintenance lifestyle programs. Structured lifestyle support plays an important role in successful weight management. A total of 34% of participants receiving structured lifestyle support from trained‐nursing staff achieved weight loss of ≥5% over 12 weeks compared with approximately 19% with usual care (Nanchahal et al., 2009 ). This particular structured program, delivered in a primary healthcare setting, included initial assessment and goal setting, an eating plan and specific lifestyle goals, personalized activity program, and advice about managing obstacles to weight loss. Additionally, data from the National Weight Control Registry (NWCR), which is the longest prospective compilation of data from individuals who have successfully lost weight and maintained their weight loss, confirm expectations that sustained changes to both diet and activity levels are central to successful weight management (Table ​ (Table2). 2 ). Therefore, an understanding of different clinical strategies for delivery‐structured support is essential for the nurse practitioner.

Lifestyle factors associated with achieving and maintaining weight loss

a Walking was the most common activity undertaken.

Realistic weight‐loss targets

From the outset, a patient's estimate of their achievable weight loss may be unrealistic. Setting realistic weight‐loss goals is often difficult because of misinformation from a variety of sources, including friends, media, and other healthcare professionals (Osunlana et al., 2015 ). Many individuals with obesity or overweight have unrealistic goals of 20%–30% weight loss, whereas a more realistic goal would be the loss of 5%–15% of the initial body weight (Fabricatore et al., 2007 ). Promoting realistic weight‐loss expectations for patients was identified as a key difficulty for nurse practitioners, primary care nurses, dieticians, and mental health workers (Osunlana et al., 2015 ). Visual resources showing the health and wellness benefit of modest weight loss may thus be helpful (Osunlana et al., 2015 ). Healthcare practitioners should focus on open discussion about, and re‐enforcement of, realistic weight‐loss goals and assess outcomes consistently according to those goals (Bray, Look, & Ryan, 2013 ).

Maintaining a food diary

The 2013 White Paper from the American Nurse Practitioners Foundation on the Prevention and Treatment of Obesity considers a food diary as an important evidence‐based nutritional intervention in aiding weight loss (ANPF). Consistent and regular recording in a food diary was significantly associated with long‐term weight‐loss success in a group of 220 women (Peterson et al., 2014 ). This group lost a mean of 10.4% of their initial body weight through a 6‐month group‐based weight‐management program and then regained a mean of 2.3% over a 12‐month follow‐up period, during which participants received bimonthly support in person, by telephone, or by e‐mail (Peterson et al., 2014 ). Over the 12‐month follow‐up, women who self‐monitored consistently (≥50% of the extended‐care year) had a mean weight loss of 0.98%, while those who were less consistent (<50%) gained weight (5.1%; p < .01). Therefore, frequent and consistent food monitoring should be encouraged, particularly in the weight‐maintenance phase of any program.

Motivating and supporting patients

Motivational interviewing is a technique that focuses on enhancing intrinsic motivation and behavioral changes by addressing ambivalence (Barnes & Ivezaj, 2015 ). Interviews focus on “change talk,” including the reasons for change and optimism about the intent for change in a supportive and nonconfrontational setting, and may help individuals maintain behavioral changes.

For patients that have achieved weight loss, the behavioral factors associated with maintaining weight loss include strong social support networks, limiting/avoiding disinhibited eating, avoiding binge eating, avoiding eating in response to stress or emotional issues, being accountable for one's decisions, having a strong sense of autonomy, internal motivation, and self‐efficacy (Grief & Miranda, 2010 ). Therefore, encouraging feelings of “self‐worth” or “self‐efficacy” can help individuals to view weight loss as being within their own control and achievable (Cochrane, 2008 ).

Strengthening relationships with patients with overweight or obesity to enhance trust may also improve adherence with weight‐loss programs. Patients with hypertension who reported having “complete trust” in their healthcare practitioner were more than twice as likely to engage in lifestyle changes to lose weight than those who lacked “complete trust” (Jones, Carson, Bleich, & Cooper, 2012 ). It may be prudent to ensure the healthcare staff implementing weight‐loss programs have sufficient time to foster trust with their patients.

Continued support from healthcare staff may help patients sustain the necessary motivation for lifestyle changes. A retrospective analysis of 14,256 patients in primary care identified consultation frequency as a factor that can predict the success of weight‐management programs (Lenoir, Maillot, Guilbot, & Ritz, 2015 ). Individuals who successfully maintained ≥10% weight loss over 12 months visited the healthcare provider on average 0.65 times monthly compared with an average of 0.48 visits/month in those who did not maintain ≥10% weight loss, and 0.39 visits/month in those who failed to achieve the initial ≥10% weight loss ( p < .001; Lenoir et al., 2015 ).

Educational and environmental factors

It is important to consider a patient's education and environment when formulating a weight loss strategy as environmental factors may need to be challenged to help facilitate weight loss. A family history of obesity and childhood obesity are strongly linked to adult obesity, which is likely to be because of both genetic and behavioral factors (Kral & Rauh, 2010 ). Parents create their child's early food experiences and influence their child's attitudes to eating through learned eating habits and food choices (Kral & Rauh, 2010 ). Families can also impart cultural preferences for less healthy food choices and family food choices may be affected by community factors, such as the local availability and cost of healthy food options (Castro, Shaibi, & Boehm‐Smith, 2009 ). Alongside this, genetic variation in taste sensation may influence the dietary palate and influence food choices (Loper, La Sala, Dotson, & Steinle, 2015 ). For example, sensitivity to 6‐n‐propylthiouracil (PROP) is genetically determined, and PROP‐tasting ability ranges from super taster to nontaster. When offered buffet‐style meals over 3 days, PROP nontasters consumed more energy, and a greater proportion of energy from fat compared with super tasters. So it is possible that a family's genetic profile could contribute to eating choices. To address behavioral factors, it is important to ensure that families have appropriate support and information and that any early signs of weight gain are dealt with promptly.

A healthy home food environment can help individuals improve their diet. In children, key factors are availability of fresh fruit and vegetables at home and parental influence through their own fresh fruit and vegetable intake (Wyse, Wolfenden, & Bisquera, 2015 ). In adults, unhealthy home food environment factors include less healthy food in the home and reliance on fast food ( p = .01) are all predictors of obesity (Emery et al., 2015 ).

Family mealtimes are strongly associated with better dietary intake and a randomized controlled trial to encourage healthy family meals showed a promising reduction in excess weight gain in prepubescent children (Fulkerson et al., 2015 ). Another study showed that adolescents with any level of baseline family meal frequency, 1–2, 3–4, and ≥5 family meals/week, had reduced odds of being affected by overweight or obesity 10 years later than adolescents who never ate family meals (Berge et al., 2015 ). Community health advocates have identified the failure of many families to plan meals or prepare food as a barrier to healthy family eating patterns (Fruh, Mulekar, Hall, Fulkerson et al., 2013 ). Meal planning allows healthy meals to be prepared in advance and frozen for later consumption (Fruh, Mulekar, Hall, Adams et al., 2013 ) and is associated with increased consumption of vegetables and healthier meals compared with meals prepared on impulse (Crawford, Ball, Mishra, Salmon, & Timperio, 2007 ; Hersey et al., 2001 ).

The role of the nurse practitioner

The initial and ongoing interactions between patient and nurse practitioner are keys for the determination of an effective approach and implementation of a weight loss program and subsequent weight maintenance. The initial interaction can be instigated by either the nurse practitioner or the patient and once the decision has been made to manage the patient's weight, the evaluation includes a risk assessment, a discussion about the patient's weight, and treatment goal recommendations (American Nurse Practitioner Foundation, 2013 ). Across this process, it may be advantageous to approach this using objective data and language that is motivational and/or nonjudgmental. Patients may struggle with motivation, and therefore, ongoing discussions around the health benefits and improvements to quality of life as a result of weight loss may be required (American Nurse Practitioner Foundation, 2013 ). It may be valuable to allocate personalized benefits to the weight loss such as playing with children/grandchildren (American Nurse Practitioner Foundation, 2013 ). Treatment approaches encompass nonpharmacological and pharmacological strategies; however, it is important to remember that any pharmacological agent used should be used as an adjunct to nutritional and physical activity strategies (American Nurse Practitioner Foundation, 2013 ). Pharmacotherapy options for weight management are discussed further in the article by Golden in this supplement.

Conclusions/summary

The importance of obesity management is underscored both by the serious health consequences for individuals, but also by its increasing prevalence globally, and across age groups in particular. Obesity promotes a chronic, low‐grade, inflammatory state, which is associated with vascular dysfunction, thrombotic disorders, multiple organ damage, and metabolic dysfunction. These physiological effects ultimately lead to the development of a range of morbidities, including CVD, T2D, OSA, and certain cancers along with many others, as well as causing a significant impact on mortality.

However, even modest weight loss of 5%–10% of total body weight can significantly improve health and well‐being, and further benefits are possible with greater weight loss. Weight loss can help to prevent development of T2D in individuals with obesity and prediabetes and has a positive long‐term impact on cardiovascular mortality. Beneficial, although not curative, effects have also been noted on OSA following >10% weight loss. In addition, weight loss reduces the risk for certain cancer types and has positive effects on most comorbidities including asthma, GERD, liver function, urinary incontinence, fertility, joint pain, and depression.

Weight‐loss programs that include realistic weight loss goals, frequent check‐in, and meal/activity diaries may help individuals to lose weight. Setting realistic weight‐loss goals can be difficult; however, visual resources showing the health and wellness benefit of weight loss may be helpful in discussing realistic goals, and help motivate the patient in maintaining the weight loss. Techniques such as motivational interviewing that focus on addressing resistance to behavioral change in a supportive and optimistic manner may help individuals in integrating these changes to allow them to become part of normal everyday life and thus help with maintaining the weight loss. Positive reinforcement in terms of marked early‐weight loss may also assist in improving adherence, so this should be a key goal for weight‐loss programs. Encouraging feelings of “self‐worth” or “self‐efficacy” can help individuals to view weight loss as being within their own control.

Nurse practitioners play a major role in helping patients achieve weight loss through all aspects of the process including assessment, support, motivation, goal‐setting, management, and treatment. With their in‐depth understanding of the research in the field of obesity and weight management, nurse practitioners are well placed to effect meaningful changes in the weight‐management strategies deployed in clinical practice.

Obesity in America: Cause and Effect Essay Sample

It is clear that the American lifestyle has contributed to the increasing prevalence of obesity. With estimates from the Washington-based Centers for Disease Prevention in the Department of Health and Human Services indicating that one in three American adults is overweight, it is evident that the country is facing an obesity epidemic. To better understand the causes and effects of obesity, research is needed to further explore the issue. For those struggling with obesity, coursework assistance may be available to help them make the necessary lifestyle changes in order to live a healthier life.

Writing a thesis paper on the topic of obesity can be extremely challenging. It requires extensive research and time to adequately cover the subject. However, there are services available that can provide assistance with the writing process. Pay for a thesis allows for the benefit of having an experienced professional provide guidance and support throughout the entire process.

Causes of Obesity

Every phenomenon must have a reason. In order to write a cause and effect essay , you need to analyze the topic carefully to cover all aspects. Obesity is considered to be a complex illness, with a number of factors contributing to its development. These can be:

• hereditary;

As you may have guessed, it is the latter category of causes and effects that we are interested in. At this point, we care about the five ones that have made the biggest contribution.

Product Range

The main cause of obesity is junk food and an unbalanced diet rich in simple carbohydrates, fats, and sugars, plus a bunch of additives. Manufactured, processed, refined, and packaged meals are the most popular. Thanks to advances in technology, Americans have come to mass-produce meals that keep fresh longer and taste better. It takes less time to prepare unhealthy, processed foods in the microwave than it does to cook them yourself.

Lack of a work-life balance, high-stress levels, insufficient sleeping hours contribute to body weight gain. Not only do these factors contribute to this, but failing to take the time to do your homework can also have a negative impact on your physical health. Without a healthy, balanced approach to work, rest, and play, you may find yourself increasingly dependent on a sedentary lifestyle that can lead to overweight consequences. Many Americans work 50, 60, or more hours a week and suffer from a deficit of leisure hours. Cooking processed foods saves them hours and money, even though they end up costing them a lot more – by causing cardiovascular disease. In addition, obese people feel stressed on a regular basis in the United States metropolitan areas. Many of them are simply binge eating under the influence of negative emotions. Chronic overeating leads to a disturbance in the appetite center in the brain, and the normal amount of food eaten can no longer suppress hunger as much as necessary, affecting the body mass.

Food Deserts

The term ‘ food desert ‘ refers to poor areas (urban, suburban and rural) with limited access to fresh fruit, grains, and vegetables – places where it is much easier to access junk food. A grocery shop in a food desert that sells healthy foods may be 10-15 miles away, while a mini-market or cheap shop that sells harmful snacks is close to the house. In such a world, it takes much more effort to eat healthier, form eating habits, and stay slim.

Everyone’s Passion for Sweets

Consuming sweets in large quantities is addictive: the more and easier we give the body energy, the more the brain uses serotonin and dopamine to encourage it – it will make obese people want sweets again and again during the day. Cakes and pastries are fast carbohydrates that easily satisfy hunger and increase body mass. Despite the harm of sweets, obese people experience the need for them to satiate. Sweetened carbonated drinks are one of the main sources of sugar in the American diet. Moreover, some individuals may be more adversely affected by such diets than others: patients with a genetic predisposition to obesity gain body mass faster from sugary drinks than those without it. This leads to childhood obesity.

The Harm of Tolerance

Every year, the body positive movement is becoming more and more popular all over the world. It would seem that this major trend should have freed us from the problems associated with the cult of thinness and society’s notorious standards. In many ways, a positive attitude towards the body has proved fruitful. For example, the notion of beauty has clearly broadened. Now on fashion shows and magazine covers, you can see not only a girl with perfectly retouched skin and without a single hint of body fat but also an ordinary person with its inherent features: overweight, wrinkles, hair, and individual skin features. In general, all the things that we are all so familiar with in real life.

Does it really make that much sense? Is this a positive thing in terms of the cause and effect topic regarding obesity? In short, opinions are divided. Extremes aren’t easy to overcome. Not everyone manages to do it. Researchers have concluded that due to plus size having become positioned as a variant of the norm, more persons have become obese. Many obese Americans have formed the opinion that it is really quite normal, and they have become oblivious to the damage it does to their health. This is what we are going to focus on next.

Effects of Obesity

We all know that obesity is dangerous to health. However, medical studies show that most adults are unaware of the number of complications and diseases that obesity in America entails. So they are fairly comfortable with becoming gradually fatter. But indifference is replaced by concern when obesity related diseases begin to occur.

For interesting examples of students writing that also reveal the causes and effects of other phenomena, consult the custom essay service offering essays by professionals. In this way, you will realize the importance of highlighting the effects right after the causes.

Is obesity an aesthetic disadvantage, an inconvenience, a limitation in physical activity or is it an illness after all? How does it affect health, and what are the consequences? The visible signs of obesity are by no means the only complication associated with this condition. Obesity creates a high risk of life-threatening diseases such as atherosclerosis, hypertension, heart attack, myocardial infarction, and kidney and liver problems. Moreover, it can also lead to disability.

Cardiovascular Disease

This is the most serious and damaging impact on the body and blood vessels in particular. Every extra kilo is a huge additional load on the heart. Obesity increases the risk of heart attacks. Experts from the American Heart Association have developed a paper on the relationship between obesity and cardiovascular disease, which discusses the impact of obesity on the diagnosis and outcomes of patients with atherosclerotic cardiovascular disease, heart failure, and arrhythmias. Childhood obesity aggravates the course of cardiovascular disease from a very early age. The fact that even kids and adolescents are obese is associated with high blood pressure, dyslipidemia, and hyperglycemia.

The result is excessive insulin production in the body. This, in turn, leads to an overabundance of insulin in the blood, which makes the peripheral tissues more resistant to it. As a consequence of the above, sodium metabolism is disturbed, and blood pressure rises. It is important to remember that excessive carbohydrate food intake leads to increased production of insulin by the pancreas. Excess insulin in the human body easily converts glucose into fat. And obesity reduces tissue sensitivity to insulin itself. This kind of vicious circle leads to type 2 diabetes.

Effects on Joints

Obesity increases the load on joints to a great extent, especially if one undergoes little or no physical activity. For instance, if one lives in a megalopolis, where all physical activity consists of getting off the sofa, walking to the car, and plumping up in an office chair at work. All this leads to a reduction in muscle mass, which is already weak, and all the load falls on the joints and ligaments.

The result is arthritis, arthrosis, and osteochondrosis. Consequently, a seemingly illogical situation is formed – there is practically no exercise, but joints are worn out harder than in the case of powerlifters. In turn, according to a study by the University of California, reducing body weight reduces the risk of osteoarthritis.

Infertility

In most cases, being obese leads to endocrine infertility, as it causes an irregular menstrual cycle. Women experience thyroid disease, polycystic ovarian syndrome, problems with conception, and decreased progesterone hormone. Obese men are faced with erectile dysfunction, reduced testosterone levels, and infertility. It should be noted that the mother’s obesity affects not only her health but also the one of her unborn child. These children are at higher risk of congenital malformations.

Corresponding Inconveniences

Public consciousness is still far from the notion that obese people are sick individuals. The social significance of the issue is that people who are severely obese find it difficult to get a job. They experience discriminatory restrictions on promotion, daily living disadvantages, restrictions on mobility, clothing choices, discomfort with adequate hygiene, and sexual dysfunction. Some of these individuals not only suffer from illness and limited mobility but also have low self-esteem, depression, and other psychological problems due to involuntary isolation by watching television or playing video games. Therefore, the public has to recognize the need to establish and implement national and childhood obesity epidemic prevention programs.

Society today provokes unintentional adult and childhood obesity among its members by encouraging the consumption of high-fat, high-calorie foods and, at the same time, by technological advances, promoting sedentary lifestyles like spending time watching television or playing video games. These social and technological factors have contributed to the rise in obesity in recent decades. Developing a responsible attitude towards health will only have a full impact if people are given the opportunity to enjoy a healthy lifestyle. At the level of the community as a whole, it is therefore important to support people in adhering to dieting recommendations through the continued implementation of evidence-based and demographic-based policies to make regular physical activity and good nutrition both affordable and feasible for all. It is recommended to cut down on the food consumed.

What is Obesity

What is obesity? Obesity and BMI (body mass index) are both tools of measurement that are used by doctors to assess body fat according to the height, age, and gender of a person. If the BMI is between 25 to 29.9, that means the person has excess weight and body fat.

If the BMI exceeds 30, that means the person is obese. Obesity is a condition that increases the risk of developing cardiovascular diseases, high blood pressure, and other medical conditions like metabolic syndrome, arthritis, and even some types of cancer.

Obesity Definition

Obesity is defined by the World Health Organization as an accumulation of abnormal and excess body fat that comes with several risk factors. It is measured by the body mass index BMI, body weight (in kilograms) divided by the square of a person’s height (in meters).

Obesity in America

Obesity is on the verge of becoming an epidemic as 1 in every 3 Americans can be categorized as overweight and obese. Currently, America is an obese country, and it continues to get worse.

Causes of obesity

Do you see any obese or overweight people around you?

You likely do.

This is because fast-food chains are becoming more and more common, people are less active, and fruits and vegetables are more expensive than processed foods, thus making them less available to the majority of society. These are the primary causes of obesity.

Obesity is a disease that affects all age groups, including children and elderly people.

Now that you are familiar with the topic of obesity, writing an essay won’t be that difficult for you.

Obesity: Health consequences of being overweight

What is not widely known is that the risk of health problems starts when someone is only very slightly overweight, and that the likelihood of problems increases as someone becomes more and more overweight. Many of these conditions cause long-term suffering for individuals and families. In addition, the costs for the health care system can be extremely high.

The good news is that overweight and obesity are largely preventable. The key to success is to achieve an energy balance between calories consumed on one hand, and calories used on the other hand.

To reach this goal, people can limit energy intake from total fats and shift fat consumption away from saturated fats to unsaturated fats; increase consumption of fruit and vegetables, as well as legumes, whole grains and nuts; and limit their intake of sugars. And to increase calories used, people can boost their levels of physical activity - to at least 30 minutes of regular, moderate-intensity activity on most days.

Diet and physical activity: a public health priority

Definition and Overview

The World Health Organization (WHO) defines overweight and obesity as having “excessive fat accumulation that presents a risk to health.” There are various methods to calculate body fat , as each range in accuracy and can have limitations. Body mass index (BMI) is one tool used to screen for excessive body fat. A BMI value of more than 25 is categorized as overweight, and a BMI value of more than 30 is categorized as obese.

Why use BMI?

Health impacts.

There are negative health impacts associated with excess body fat. The WHO estimates that in 2019, 5 million deaths from noncommunicable diseases such as cardiovascular disease and diabetes were caused by a high BMI, and rates of obesity continue to grow globally in children and adults. [1] According to the Centers for Disease Control and Prevention in the U.S., 1 in 5 children and 1 in 3 adults has obesity. [2] Children with obesity are more likely to have obesity as adults and the associated risks of heart disease, high blood pressure, type 2 diabetes, and certain types of cancer.

A healthy amount of body fat in children and teens varies based on age as well as sex. The Centers for Disease Control and Prevention (CDC) developed growth charts for boys and girls ages 2-19 that show the distribution of BMI values at each age. [3] By the CDC’s definition, a child whose BMI falls between the 85th and 94th percentile for age and sex is considered overweight; a BMI at the 95th percentile or higher for age is considered obese. As the rates of obesity rise in children, there is also a category for severe obesity in which the BMI is 120% of the 95th percentile. The American Academy of Pediatrics provides more specific classifications of severe obesity:

• Class 2 Obesity: BMI ≥120% to <140% of the 95th percentile or BMI ≥35 to <40 kg/m 2
• Class 3 Obesity: BMI ≥140% of the 95th percentile or BMI ≥40 kg/m 2

Obesity can negatively affect nearly every system in a child’s body – the heart, lungs, muscles, bones, kidneys, digestive tract, and hormones that control blood sugar and puberty – and can also take a heavy social and emotional toll. Children with obesity may be burdened by stigma and discrimination from bullying, teasing and victimization. Youth with obesity have substantially higher odds of remaining overweight or obese into adulthood increasing their risk of disease and disability later in life. [4]

The risk of developing diabetes, heart disease, and other weight-related health risks increases with an increasing body mass index (BMI). But evidence shows that in some ethnic and racial groups, weight gain and higher fat mass even if BMI remains in the normal range can still increase health risks.

The Nurses’ Health Study tracked patterns of weight gain and type 2 diabetes (T2D) development in 78,000 U.S. women to see differences by ethnic group. [5] All women were healthy at the start of the study. After 20 years, researchers found that at the same BMI, Asians had more than twice the risk of developing T2D than Whites; Hispanics and Blacks also had higher risks of diabetes than Whites, but to a lesser degree. Increases in weight over time were more harmful in Asians than in other ethnic groups – for every 11 pounds Asians gained during adulthood, they had an 84% increased risk of T2D; Hispanics, Blacks, and Whites who gained weight also had higher risk, but to a much lesser degree than Asians. Other studies have found that even with a lower BMI than Whites, increasing weight in Asians with a BMI of 25 or higher increased risk of high blood pressure, T2D, and early death from all causes. [6-8]

One reason for this difference could be amount and location of body fat. Even with a lower BMI than other populations, Chinese and South Asians tend to carry higher abdominal fat than Whites, which increases the risk for T2D, cardiovascular disease, and other metabolic disorders. [9-11] In contrast, some studies have found that blacks have lower body fat and higher lean muscle mass than whites at the same BMI, and therefore at the same BMI, may be at lower risk of obesity-related diseases. [12,13]

For this reason, the World Health Organization and other organizations have recommended a lower BMI cutoff to classify obesity in Asian people (BMI of 25-27 or greater) as well as a smaller waist circumference to measure visceral fat. [9,14]

Weight gain of greater than 10 pounds in adulthood also increases disease risk (i.e., heart disease, high blood pressure, type 2 diabetes, gallstones) even in those whose BMI remains in the normal range, according to research from the Nurses’ Health Study and Health Professionals Follow-up Study. [15-19]

With the five leading causes of death – heart disease, cancer , chronic lower respiratory disease, cerebrovascular diseases such as stroke, and unintentional injuries – obesity is a major risk factor for the first four. [20] Obesity is also associated with other health conditions such as sleep apnea, fatty liver disease, gallstones, infertility, respiratory diseases, gastroesophageal reflux disease, and musculoskeletal disorders such as arthritis. No less real are the social and emotional effects of obesity which may include discrimination, lower quality of life, and susceptibility to depression.

Economic Impacts

Obesity costs the U.S. health care system almost $173 billion annually. [2] This includes money spent directly on medical care and prescription drugs related to obesity. In the workplace, research has shown that the number of sick days, short-term disability, and workers’ compensation days increase with increasing BMI. [21] Compared with an employee with a BMI of 25, an employee with a BMI of 35 has nearly double the risk of a disability or workers’ compensation claim. Perhaps one of the most surprising consequences of the current obesity epidemic in the U.S. is its impact on recruitment for the armed services, with data showing that 3 in 5 young adults carry too much weight to qualify for military service. [2]

According to the WHO, worldwide obesity rates are rising with 1 in 8 people, or more than 1 billion people, around the world living with obesity. [14] A Lancet review showed that global adult obesity doubled from 1990 to 2022, and adolescent obesity quadrupled. [22] As low to middle-income countries adopt unhealthy eating patterns and behaviors of industrialized nations such as less physical activity, so do their obesity rates. Specific regions including Polynesia, Micronesia, the Caribbean, the Middle East, and north Africa showed the greatest increases in obesity, as well as higher-income countries such as Chile. [22] Increased eating out of home, access to ultra-processed low-nutrient-dense foods, and sedentariness (e.g., sitting at work, driving instead of walking or bicycling) have contributed. Higher cost and limited access to healthy foods and decreased opportunities for play and sports may cause inequalities in obesity and could limit the impact of policies that target unhealthy foods. [22]

The NCD Risk Factor Collaboration visualizes the prevalence of obesity globally as well as changing obesity rates in various countries since 1990. Below are data summaries of obesity rates for both adults and children around the world:

In 2018, the United States had the highest prevalence of adult obesity among high-income Western countries worldwide. [23]   From 1999 through 2018, the age-adjusted prevalence of adults with obesity increased significantly from 31% to 42%. [24]. If trends continue, projections estimate that by 2030 nearly 50% of adults will have obesity, and nearly 1 in 4 adults will have severe obesity (BMI ≥35). [25]

Obesity disproportionately affects U.S. racial/ethnic minority populations. Compared to 42% of non-Hispanic whites, 50% of non-Hispanic Black and 45% of Hispanic adults have obesity. [24] There are considerable differences in obesity among non-Hispanic Black adults by sex, with 57% of non-Hispanic Black women having obesity compared to 41% of men. [24] Trends estimate that severe obesity may become the most common BMI category among non-Hispanic Black and low-income adults by 2030. [25]

Obesity rates in Canada are not as high as they are in the U.S., but Canada has seen dramatic increases over the past three decades. Obesity prevalence among Canadian adults increased from 9% in 1975 to 31% by 2016. [23] Indigenous populations in Canada are also disproportionately affected by the burden of obesity. [26]

The U.S. has among the highest childhood obesity rates in the world, with nearly 1 in 3 children with overweight or obesity. In 2015-2016, nearly 19% of children 2-19 years old had obesity, affecting an estimated 14 million children nationwide. Obesity prevalence was highest among adolescents 12-19 years old (21%) and lowest among preschool-aged children 2-5 years old (14%). [27] Recently, the prevalence of obesity declined among children ages 2-5 years old, held steady for children 6-11 years, and continued to rise among adolescents 12-19 years. [28,29] Current trends suggest that an alarming 57% of children currently between 2 and 19 years old will have obesity at age 35. [30]

Overweight and obesity disproportionally affects racial/ethnic minority populations, and such disparities exist as early as age 2 and persist into adulthood. [27,30] The highest obesity prevalence are among Hispanic (26%) and non-Hispanic Black children (22%), compared with the lowest prevalence among non-Hispanic White (14%) and non-Hispanic Asian (11%) children. [27]

Canada has also seen a rise in childhood obesity since the late 1970s. Obesity rates have more than doubled, and in some age groups, tripled. [31] But childhood obesity rates are lower there than they are in the U.S; in 2013, 10% of children ages 6-11 years old and 17% of children ages 12-17 had obesity. [32] Childhood obesity is significant among Canada’s Aboriginal groups. In a 2006 survey of Aboriginal Peoples in Canada, nearly 33% of children ages 6-8 had obesity, and 13% among children ages 9-14. [33]

Over the past several decades, obesity has become a significant health challenge in Latin America. While undernourishment persists among vulnerable groups, so do overweight and obesity. Each year, obesity among the population grows by 3.6 million individuals, and now exceeds undernourishment as the greatest nutritional threat. [34] Between 1975 and 2014, among the largest increases in BMI in regions worldwide occurred for men in central Latin America, and for women in Andean Latin America and the Caribbean. [35] In 2016, approximately 104 million adults in Latin America had obesity; 15% of men and 16% of women. [23] Countries with the highest prevalence of obesity included Bermuda (women 43%, men 30%) and Puerto Rico (women 42%, men 29%). [23]

While Latin America has shown significant progress in reducing child stunting due to undernourishment, prevalence of overweight and obesity due to malnutrition has grown to be among the highest in the world. [34] As a result, Latin American children have the dual burden of undernutrition coexisting with overweight and obesity. [36] In 2016, 15% of children ages 5-9 years and 10% of adolescents ages 10-19 years had obesity in Latin America and the Caribbean. [34] Among girls ages 5-19 years old, central Latin America demonstrated the highest increase of BMI per decade worldwide over the past 40 years. [37] Inequality further exacerbates overweight and obesity in populations with lower income, and among women, indigenous peoples, Afro-descendants, and rural families. [34]

Since 1975, obesity rates have been rising across Europe, though not as rapidly or as high as they are in the U.S. [35] Countries with the highest prevalence include Malta and the United Kingdom, hovering around 30% for both men and women. Countries with the lowest obesity prevalence include Austria, Sweden, Denmark, and Switzerland for women and Moldova and Russia for men (<20% for all). [23] The rise in women’s BMI in central and southwestern Europe has been among the lowest over the past 40 years, one of the few places worldwide that can report such a trend. [23,35]

Over the past several decades, many European countries had among the largest increases in the number of children and adolescents with obesity. [37] More recently, obesity has plateaued in many regions, particularly in eastern, northwestern, and southwestern Europe, but prevalence rates remain high in Mediterranean countries. [37,38] In Greece, Malta, and Cyprus, 16% of boys ages 5-19 have obesity, and 11% of girls in Greece and Malta. [37]  

Regional surveys and analyses demonstrate similar childhood obesity trends in Europe. A 2019 systematic review of 130 studies across 28 European countries assessed prevalence trends in overweight and obesity among 2-13-year-old children between 1999-2016. [39] The prevalence of overweight and obesity tended to decrease in the Iberian region and increase in the Mediterranean regions, with no significant changes in Atlantic or Central Europe. Although the overall prevalence of childhood overweight and obesity remains high, trends have stabilized in most European countries, but continues to rise in some Mediterranean countries. [39]

Undernutrition has historically received more public health attention in Africa than overnutrition. Yet today, obesity and associated chronic diseases have become a growing problem across the continent. Some have called it a “silent epidemic,” striking countries that are still struggling with the health and economic burdens of malnutrition, stunting, infectious disease, and high childhood mortality rates. [40]

Obesity prevalence is higher among African women compared with men, and can vary widely from country to country. For example in 2016, 41% of women in South Africa had obesity (higher than in U.S. women) compared with 16% of men. In stark contrast, the lowest prevalence of obesity was in Ethiopia for women (7.3%) and in Uganda for men (2%); prevalence of undernutrition exceeds that of overnutrition in these African countries among many others. [35]  Between 1975 and 2016, Botswana experienced the largest increases in obesity prevalence in these African regions, jumping from 5% to 31%. [35]

Hunger, underweight, and stunting have long been the more pressing child nutrition concerns across Africa. Even today, more children and adolescents are moderately or severely underweight than obese, particularly in central, east, and west Africa. [35] Yet here too, child obesity rates are on the rise, particularly in southern Africa. In 1975, less than 0.5% of girls and boys in South Africa had obesity, but by 2016 the prevalence jumped to 13% for girls and 10% for boys. [37]

Researchers have taken a closer look at obesity trends in the six Persian Gulf states (Oman, Bahrain, United Arab Emirates, Saudi Arabia, Qatar, and Kuwait), since these countries have seen tremendous increases in wealth since the discovery of oil reserves in the 1960s. [41] Even in 1975, obesity prevalence in Kuwait, Qatar, and the United Arab Emirates exceeded 20% among women, raking among the top 20 countries worldwide with the highest prevalence. Among men, Kuwait and Qatar also ranked among the top 20 countries with the highest prevalence in 1975, but only at 12%. [23] In 2016, the prevalence of obesity increased to 47% in Kuwait and 45% in Qatar for women, and to approximately 30% for men in both countries. The most significant increases have been observed in Saudi Arabia and Jordan, from 6% in 1975 to around 30% in 2016. [23]

The Middle East and north Africa have seen sharp increases in obesity since 1975, and this region now has among the highest prevalence of child and adolescent obesity worldwide. [38] Girls in Kuwait and Egypt and boys in Kuwait, Qatar, and Saudi Arabia have the highest obesity prevalence in the region, all hovering around 20% of the child and adolescent population. [37] In 1975, girls in the Middle East and north Africa had higher age-standardized BMI than boys, but by 2016 this gap shrank or reversed as boys gained more weight than girls. [37]

Some countries in Asia have the lowest obesity prevalence worldwide, yet here too it has become a serious problem across the region over the past four decades, even while underweight concerns persist. Japan and South Korea have among the lowest obesity prevalence in the world (<9%) for both men and women. However, recent trends in China are of special concern. Although obesity rates are still low overall, there has been a substantial increase from <1% in 1978, to 6% for women and 7% for men in 2016. [23] China is one of the most populous nations on the planet with more than 1.4 billion people, so even small percentage increases in obesity prevalence translate into millions more cases of chronic disease. Furthermore, Asians have a higher risk of weight-related diseases like type 2 diabetes at lower BMI levels , further exacerbating the health issues related to overweight and obesity.

South Asian countries like Bangladesh, India, and Pakistan have among the highest prevalence of moderate and severe underweight worldwide; 20% in girls and 29% in boys. Nevertheless, trends in mean BMI have significantly accelerated in east, south, and southeast Asia between 1975 and 2016. Although obesity prevalence remains relatively low in south Asia, their large populations add up to large numbers of children who have obesity.

Compared to south Asia, the prevalence of child and adolescent obesity is greater in high income Asia Pacific and east/southeast Asia, particularly among boys. [37,38] Obesity prevalence in Malaysia, Taiwan, and China for boys was less than 0.5% in 1975 and jumped to 15% in 2016. Girls in Asia have lower obesity prevalence compared to boys, but has still been increasing over time, most notably in Malaysia where obesity increased from 0.2% to 10% during this time period. [37]  

It’s important to note that in Asian adults, the health complications associated with overweight and obesity start at a lower BMI than seen in the U.S. and Europe; therefore these estimates of child obesity prevalence in Asia likely underestimate the true public health burden of obesity in Asia.

The top 13 countries with the highest obesity prevalence worldwide are located within Oceania. Eight of the countries exceed 45% obesity prevalence among men, and 13 countries exceed 50% among women. American Samoa and Nauru have the highest obesity prevalence among women (68%) worldwide; for men it is Nauru at 60%. Australia and New Zealand have lower prevalence in the region but still hover around 30% for both men and women. [23]

Of the top 13 countries with the highest child and adolescent obesity prevalence in 2016, 11 were located in Oceania. There was more than 30% obesity prevalence for both girls and boys in the Cook Islands, Nauru, Palau, and additionally for boys in Niue and American Samoa. [37]

High-income countries in Oceania, Australia and New Zealand have childhood obesity rates in the double digits, but there’s some evidence that rates have hit a plateau. In Australia, 13% of boys and 11% of girls have obesity; in New Zealand the prevalence is higher at 18% and 15% respectively. [37] Overweight and obesity prevalence is even higher in some of New Zealand’s ethnic groups (Maori, 37%; Pacific Islanders, 57%) but have largely unchanged since early 2000. [42]

Risk Factors

Various factors can influence body weight or greater weight gain in specific areas of the body. Some of these cannot be changed, but others may be modified:

• Non-modifiable risk factors (risk factors you can’t change): age, gender, genes, ethnic origin, and sometimes medications that change how energy is processed in the body leading to weight gain. There’s also strong evidence that having obesity in infancy or childhood increases the chances of remaining obese in adulthood.
• Risk factors that can be modified: food and beverages consumed, level of physical activity, daily screen time (increased screen time is associated with reduced physical activity time and also increases exposure to marketing of unhealthy foods/beverages), poor sleep hygiene, uncontrolled negative stress. While easier said than done, evidence has shown that addressing these factors as early as possible, even in childhood, may reduce the risk of developing obesity.

Obesity is complex and not just about being born with a certain body size, taking in more calories than the body needs, or burning extra calories through exercise to lose weight. It is often the result of a combination of several non-modifiable and modifiable risk factors. When looking at diet and food, which is often the focus with obesity, there are various factors to consider than just calories in/calories out:

• Living in a food environment that lacks access to healthy food choices or income-related barriers to regularly consuming a variety of healthy foods.
• Amount of low-nutrient ultra-processed foods and sugary beverages consumed, especially when displacing high-fiber whole foods, which can increase cravings .
• Eating behaviors such as skipping meals and eating heavy meals or snacks at night before bed.
• Overeating portions not from hunger but from stress or boredom.

The environments that surround us also play an important role, as they can make a modifiable risk factor a non-modifiable one. Examples are when someone does not have the ability to secure healthy food choices due to living in a food desert or a safe place to perform regular physical activity .

There are various risk factors for obesity, but not everyone with these risk factors develops obesity. And not everyone who has obesity develops health problems. In these cases, genes may play a role. Studies of siblings or twins show genetic factors that can determine weight and body size throughout life. [43] Some research suggests differences in genes in people who are of normal weight versus those carrying extra weight that may influence appetite control, metabolic rate, or even ability to change behavior. Gene-nutrient interactions can also promote obesity. For example, genes that increase risk of developing obesity have been reported to be stimulated by saturated fatty acids but not by unsaturated fatty acids . [43] The gut microbiome may also play a role in a person’s risk of developing obesity and chronic health conditions. [44]

However, obesity caused by mutations in a single gene, or monogenic obesity, is rare and is more likely influenced by changes in many different genes, called “common” obesity. Still, the modern obesity epidemic is largely fueled by environmental factors, with excess energy intake and low physical activity pinned as the main culprits. [45] First-degree family members (parents, siblings) who live together typically share similar environments that increase the risk of obesity, and health-related habits of parents are often passed onto their children. Examples include food choices, meal preparation methods (cooking at home vs. reliance on fast food), exercise, screen time, and sleep habits, as well as lack of access to outdoor green space.

These findings suggest that genetic factors make a small contribution to obesity risk, and that our genes are not our destiny. Many people who carry potential “obesity genes” do not become overweight, and healthy lifestyles can counteract these genetic effects.

Is Prevention Possible?

Many factors contribute to rising rates of obesity in children and adults. Among them, the abundance of low-priced, high-calorie ultra processed foods and sugary drinks; incessant marketing driving people to eat more; and an environment that reduces the need for regular physical activity.

Although preventing weight gain over the years of life may not be possible for everyone due to a variety of circumstances, there are strategies to reduce the amount of weight change by increasing awareness of modifiable risk factors and working toward healthy lifestyle behaviors.

However, focusing only on the individual (e.g., nutrition and lifestyle education, weight loss medications) has little impact on global obesity prevalence. Prevention requires a broader scope that addresses food systems and an obesogenic environment , including policy changes such as regulating the marketing of ultra-processed low-nutrient-dense foods and taxing items such as sugar-sweetened beverages.

Indeed, what sometimes gets lost in the discussion is that obesity is preventable . We can turn around the obesity epidemic by collaboratively creating an environment where the default option is the healthy choice.

The prevalence of obesity has increased worldwide in the past ~50 years, reaching pandemic levels. Obesity represents a major health challenge because it substantially increases the risk of diseases such as type 2 diabetes mellitus, fatty liver disease, hypertension, myocardial infarction, stroke, dementia, osteoarthritis, obstructive sleep apnoea and several cancers, thereby contributing to a decline in both quality of life and life expectancy. Obesity is also associated with unemployment, social disadvantages and reduced socio-economic productivity, thus increasingly creating an economic burden. Thus far, obesity prevention and treatment strategies — both at the individual and population level — have not been successful in the long term. Lifestyle and behavioural interventions aimed at reducing calorie intake and increasing energy expenditure have limited effectiveness because complex and persistent hormonal, metabolic and neurochemical adaptations defend against weight loss and promote weight regain. Reducing the obesity burden requires approaches that combine individual interventions with changes in the environment and society. Therefore, a better understanding of the remarkable regional differences in obesity prevalence and trends might help to identify societal causes of obesity and provide guidance on which are the most promising intervention strategies.

Obesity prevalence has increased in pandemic dimensions over the past 50 years.

Obesity is a disease that can cause premature disability and death by increasing the risk of cardiometabolic diseases, osteoarthritis, dementia, depression and some types of cancers.

Obesity prevention and treatments frequently fail in the long term (for example, behavioural interventions aiming at reducing energy intake and increasing energy expenditure) or are not available or suitable (bariatric surgery) for the majority of people affected.

Although obesity prevalence increased in every single country in the world, regional differences exist in both obesity prevalence and trends; understanding the drivers of these regional differences might help to provide guidance for the most promising intervention strategies.

Changes in the global food system together with increased sedentary behaviour seem to be the main drivers of the obesity pandemic.

The major challenge is to translate our knowledge of the main causes of increased obesity prevalence into effective actions; such actions might include policy changes that facilitate individual choices for foods that have reduced fat, sugar and salt content.

Consequences of Obesity

Health conditions, economic impact, military readiness.

People who have obesity, compared to those with a healthy weight, are at increased risk for many serious diseases and health conditions. In addition, obesity and its associated health problems have a significant economic impact on the US health care system. Obesity also affects military readiness.

Obesity in children and adults increases the risk for the following health conditions. 1,2,3

• High blood pressure and high cholesterol which are risk factors for heart disease.
• Type 2 diabetes.
• Breathing problems, such as asthma and sleep apnea.
• Joint problems such as osteoarthritis and musculoskeletal discomfort.
• Gallstones and gallbladder disease.

Childhood obesity is also associated with: 4,5,6

• Psychological problems such as anxiety and depression.
• Low self-esteem and lower self-reported quality of life.
• Social problems such as bullying and stigma.
• Obesity as adults.

Adults with obesity have higher risks for stroke, many types of cancer , premature death, and mental illness such as clinical depression and anxiety. 7,8

Annual obesity-related medical care costs in the United States, in 2019 dollars, were estimated to be nearly $173 billion. 9 Annual nationwide productivity costs of obesity-related absenteeism range between $3.38 billion ($79 per individual with obesity) and $6.38 billion ($132 per individual with obesity). 10

Direct medical costs may include preventive, diagnostic, and treatment services. Indirect costs relate to sickness and death and include lost productivity. Productivity measures include employees being absent from work for obesity-related health reasons, decreased productivity while at work, and premature death and disability 11

Just over 1 in 3 young adults aged 17-24 is too heavy to serve in the US military [PDF-774KB] . Among the young adults who meet weight requirements, only 3 in 4 report physical activity levels that prepare them for challenges in basic training. Consequently, only 2 in 5 young adults are both weight-eligible and adequately active for military service.

Also, 19% of active-duty service members had obesity in 2020, up from 16% in 2015. These individuals are less likely to be medically ready to deploy. Between 2008 and 2017, active-duty soldiers had more than 3.6 million musculoskeletal injuries. One study found that active-duty soldiers with obesity were 33% more likely to get this type of injury.

Obesity is a condition in which excess body fat has accumulated to such an extent that it may have a negative effect on health. Medical organizations tend to classify people as obese based on body mass index (BMI) – a ratio of a person's weight in kilograms to the square of their height in meters.

There are three types of obesity: Class 1 (low-risk) obesity, if BMI is 30.0 to 34.9; Class 2 (moderate-risk) obesity, if BMI is 35.0 to 39.9; Class 3 (high-risk) obesity, if BMI is equal to or greater than 40.0.

The major contributors to obesity are: diet, sedentary lifestyle, genetics, other illnesses, social determinants, gut bacteria, and other factors.

Excessive body weight has a strong link to many diseases and conditions, particularly cardiovascular diseases, diabetes mellitus type 2, obstructive sleep apnea, certain types of cancer, osteoarthritis, and asthma. As a result, obesity has been found to reduce life expectancy.

Most of the world's population live in countries where overweight and obesity kills more people than underweight. 39 million children under the age of 5 were overweight or obese in 2020. Worldwide obesity has nearly tripled since 1975. From 1999-2000 through 2017-March 2020, US obesity prevalence increased from 30.5% to 41.9%.
