Obesity

Accumulation of excessive body fat is known as obesity. Obesity is measured and defined in terms of body mass index (BMI). Body mass index is the numerical way of deciding the appropriate weight range according to the height of an individual. A body mass index of more than 30kg/m2 indicates obesity. It is further classified as severe, morbid and super obesity in the order as the BMI increases. Obesity is a lifestyle disease which is spreading rapidly worldwide. Individuals of all age, gender and ethnicity are affected by this disease. Still, a general trend has been observed that women are affected more than the men. The tendency to gain weight also increases with the growing age. However, an alarming trend of childhood obesity is being noticed in the recent years. Obesity renders an individual susceptible to various other diseases like hypertension, coronary artery disease, type 2 diabetes, sleep apnoea etc.

Obesity is mainly caused when the intake of the calories exceed the dissipated calories. In simple words, when one tends to eat more than his body requirement the extra fat start depositing in the body tissues giving rise to obesity. Junk food is the main culprit. Children are fonder of such unhealthy food items and hence are getting more affected by the rising incidences of obesity. The other common cause is the lack of physical activity. To properly digest the consumed food, physical exercise is compulsory. But the modern day sedentary life style leaves less time to work out. Thence, lack of exercise is a major contributing factor. However, in certain cases a plateau phase has been noticed. This generally occurs due to hormonal imbalance mainly caused by disturbance in physiological system of the body. Genetic predisposition also plays a major role as a causative factor.

...Obesity Obesity is a disease that is becoming increasingly common around the world. It is a serious medical condition that can lead to many medical issues. It is no question that America’s obesity rates are among the highest in the world. More than two-thirds of U.S. adults are overweight or obese (Ogden 2014). Obesity is on the rise among people of all ages, gender and ethnic background. The causes of obesity range from many different factors and all of them contribute to this alarming situation. Americans’ obesity has rapidly increased because of lack of physical exercise, an increase in high fat and sugary food intake, and genetic factors. Physical inactivity occurs when a person does not exercise on a daily basis. An examination of national health survey records shows Americans are exercising less, which could be driving the rising obesity rates (Bach 2014). Most people hardly exercise which is not a favorable circumstance. The percentage of women reporting no physical activity jumped from 19 percent to 52 percent between 1988 and 2010; the percentage of inactive men rose from 11 percent to 43 percent over the same period. Obesity also increased, climbing from 25 to 35 percent in women and from 20 to 35 percent in men (Bach 2014). Exercise is effective in weight loss, but most people do not accept the advantage of this preventive approach. Physical activity is rather excluded from our daily lifestyle. An excuse to not exercise is that working out is too time consuming...

...Obesity on the Rise The obesity epidemic is a very common health issue in the United States. The Center for Disease Control (2011) calls it “dangerous and expensive.” On July 8th, 2014, Medical News Today, a health news website reported that obesity in the U.S. is due to a decline in exercise, and not due to overeating. The article reports, “a study from Stanford University reported in The American Journal of Medicine suggests the rise in obesity in the US is likely due to increased sedentary lifestyles across the nation, and not eating too many calories” (Paddock, 2014, para 1). Although this health issue has received a lot of attention in the last couple of decades, the rate of obesity still continues to be high. According to the CDC, in 2011–2012, the prevalence of obesity in the U.S. has continued to increase significantly in the past 20 years; 36% of adults and 17% of children and teenagers are currently overweight. Another 17% of children and teenagers are obese (Centers for Disease Control and Prevention [CDC], 2010). The terms ‘overweight’ and ‘obese’ are determined by ‘body mass index’ or BMI. Body Mass Index (BMI) is a number determined from a person's weight and height. For an adult, a BMI from 18.5-24.9 is considered normal, a BMI between 25-29.9 is considered overweight, and a BMI greater than 30 is considered obese (CDC, 2011). This paper discusses the Medical News Today article, the topic of obesity, and how it is related to Healthy People 2020. While I agree...

...Obesity and Cancer According to the National Institute of Health, nearly two-thirds of adults in the United States are overweight or obese (2007). Research suggests that obesity may be the most preventable risk factor of cancer for non-smokers, and many studies are testing for the effects that obesity has in all cancers and at specific cancer sites. It is known that obesity plays a significant role in cancer; however, the knowledge of the relationship to all cancers and the overall health effect of excess weight in terms of total mortality from cancer is limited (Calle, Redriguez, Walker-Thurmond, & Thun, 2003). In this paper I will examine the research available on obesity and its relationship to breast cancer (in post-menopausal women), endometrial, colon, esophagus, kidney, and pancreatic cancers, and briefly mention a few other cancers currently being studied for a possible link to obesity. The rise of obesity in the last 25 years has been most prominent in the United States. It is not, however, limited to the United States; for instance, similar trends are being seen in other developing countries. As it becomes easier to access tasty but unhealthy food options and as physical activity declines, caloric intake is now exceeding caloric expenditure. Genetic factors have been shown to predispose an individual to become obese, but environmental factors are the ultimate cause for the rise of obesity within populations. It is the metabolic consequences of obesity that are...

...Obesity an American Epidemic HCS/552 Karen L. Chambers University of Phoenix Monday June 4, 2012 Professor James Hamilton Obesity an American Epidemic Numerous research studies have confirmed that poor eating habits, lack of exercise and a sedentary lifestyle are the prime contributors to obesity in the US. Because of on the go life styles, fast food consumption and microwave meals, people have sacrificed their health. Instead of eating pure, wholesome foods, many people opt to eat a diet of packaged, processed and refined foods. Obesity is a condition in which excess body fat has accumulated to such levels that a person’s health can be negatively affected. The US Centers for Disease Control and Prevention (CDC) have ranked obesity as the number one health threat in America, with an estimated 400,000 deaths annually. (Smoking causes an estimated 440,000 deaths annually) Being simply overweight is not as dangerous as being obese. An overweight person can easily lose a few pounds by monitored diets and exercise, and usually regains a healthy body and mind. Obese people cannot accomplish this as easily, no matter how much effort is exerted. Studies conducted by researchers at the University of North Carolina, Chapel Hill, examined three large, nationally representative surveys on food consumption conducted from 1987 to 1998. The survey collected data on what more than 63,000 people said that they ate. Salty snacks (crackers, chips, pretzels) increased from 1 ounce to...

...Childhood Obesity: School Prevention Children in the United States are getting heavier and heavier. As a result, schools are essential towards finding a solution in the obesity epidemic. Through solid norms and school programs such as proper nutrition standards, quality health education, quality physical education, and opportunities to do physical activity, schools can help students to adopt and maintain healthy physical and nutritional behavior. All around the country, obesity has become a great problem that affects children and adults of all races and income levels. In particular, childhood obesity is becoming a more alarming situation to address because it creates physical problems and affects mental health. The essential cause of the increase in their weight is straightforward: an excess of unhealthy eating choices compared with their physical activity. According to the National Center for Health Statistics, “An estimated 61 percent of overweight young people have at least one additional risk factor for heart disease, such as high cholesterol or high blood pressure” (National Association of State Boards Education NASBE). Consequently, social and psychological problems can emerge such as discrimination and poor self-esteem. In addition, children and young adolescents who are obese are more likely to become obese when they grow older. It is known by most people that it is fundamental to have good eating behaviors and do physical activity in order to maintain a healthy weight...

...bad day (Beller 264). Whether it’s the unhappy news of the gained weight on the thighs, age creeping up on the body, or perhaps only being uneducated in nutrition. Overall well-being should be the goal for weight control, not only to enhance the body’s appearance (Sobal 81). Being overweight can be helped; as any degree of obesity can be considered one of the most preventable causes of death in America (Frankle et al. 1). Obesity in the United States has grown over the years with no real solution, however vegetarianism can contribute to overall well-being of any individual. Karlsberg states that obesity is “the condition of being extremely overweight”, being usually about twenty percent over healthy weight (77). Even if one is not obese, but overweight, the problems that obesity has could be the same. Such as heart disease, circulatory problems, high blood pressure, type two diabetes, certain cancers, and arthritis (78). Other troubles associated with obesity include, but are not limited to are: impairing vigor, increasing fatigability, gallstones, cirrhosis of the liver, hardening of arteries, and the increase of surgical risks. These reasons make obesity the “prime reason for early breakdown of the human body,” says Dr. Charles Glen King, once the scientific director of Nutrition Foundation in 1964 (Diehl 120). Fewer calories (less energy) are needed to be consumed to maintain current weight as the body ages, which is one of the most common reasons for becoming obese. When...

...Childhood obesity is harmful I selected childhood obesity as my topic. I chose this topic because it is a major crisis that children are suffering with. I believe obese children are faced with many challenges. Many of the problems travel with them throughout adult hood. I have a family member that was an obese child. She still struggles with her weight, self-esteem, and identity today and she is thirty years old. I want to explore the damaging consequences of childhood obesity. I want to take a stand against childhood obesity. I plan on limiting the topic by exposing the mental and health problems associated with childhood obesity. The Center for disease Control and Prevention says “Childhood obesity can have a harmful effect on the body in a variety of ways” (CDC, 2012, para 5). Obese children are more likely to have high blood pressure and high cholesterol, which are risk factors for cardiovascular disease (CVD). In one study, 70% of obese children had at least one CVD risk factor, and 39% had two or more. Other health problems include: Increased risk of impaired glucose tolerance, insulin resistance and type 2 diabetes; breathing problems, such as sleep apnea and asthma, joint problems and musculosketal discomfort, fatty liver disease, gall stone, and gastro-esophageal reflux (i.e., heartburn). These are just a few of the health problems. Obese children and adolescents have a greater risk of social and psychological problems, such as discrimination and poor self-esteem...

...Michael McCarthy PED200 Factors Influencing Obesity Did you know America is ranked as one of the most obese countries in the world? If you were to just take a second to look around the reasons are quite obvious. Fast food chains are on every block. This is because unhealthy food is so much cheaper than the healthy food that we should all be eating. Also these new technology coming out every year to make our lives easier and lazier, also high amounts of stress are all factors to weight gain in our country. A study in January 2010 shows that obesity rates have reached a constant level and stayed there for the past five years, but the levels of obesity are still unacceptable. Nearly 34 percent of American adults are obese; this number is more than double the amount of 30 years ago. And the percentage of obese children has nearly tripled in that time, to 17 percent. Are we doing enough to bring these numbers down? My opinion, is no. In the past 40 years, there has been an expansion to more than 160,000 fast-food restaurants in America. These restaurants serve more than 50 million people per day. Restaurants such as McDonald's, Hardees, and Wendy’s, serve pre-cooked, frozen foods, usually thawed out by hot oil. Now, their French fries are fried in vegetable oil, and there are now healthier side options to choose from. But honestly I believe we can do so much more than just changing what kind of oil we cook fries in. Maybe we should get rid of French fries all together, and replace...

...Project Title: Analyze the reasons for the increasing obesity epidemic in the developed world Introduction ‘Obesity is defined as abnormal or excessive fat accumulation that may impair health’ (World Health Organization, 2013). To accurately define obesity, one’s body mass index (BMI) is greater than or equal to 30 means he or she is obese (ibid). Obesity is increasingly spread all over the world and becomes a global health issue. According to WHO (2013), the population of the obese is twice larger than that three decades ago and more than 500 million adults are obese currently. Obesity can give a rise to the likelihood of getting other serious illness such as diabetes, cancer and CVD. Therefore, over 2.8 million lives are claimed by obesity directly or indirectly per year (ibid). Both developed and developing countries are experiencing this increasing obesity epidemic, but there are distinctions in the factors in these two kinds of areas. In comparison, the reasons in developed regions are more common problems and are more familiar to people living in urban areas. Investigation into the causes for the increasing obesity epidemic in developed countries gives the public a deeper understanding of obesity causes and helps governments make policies to tackle obesity crisis. Causes of this increasing trend are grouped into three categories in this essay, which are unhealthy food, excessive food consumption and lack of physical exercise.
