What is obesity? The term “obese” describes weight ranges that are above what is medically accepted as healthy. It occurs when you eat and drink more calories than you burn through exercise and normal daily activities. Your body stores these extra calories as fat. Obesity also has an affect on things other than your weight like: your energy, health, and economic wellbeing. Obesity has been increasing lately and, despite the many causes of it, the most standard are psychological, environmental, and genetic.
The most obvious symptom of obesity is being overweight. If a person has a Body Mass Index (BMI) of 30 or greater, then he/she is obese. Due to the extra fat in the neck and chest, an obese person may need to take short, shallow breaths. That makes it difficult for air to flow easily in and out of their lungs, which leads to a shortage of oxygen in their blood. Due to the lack of oxygen in their body, they get exhausted easily and may take a lot of effort to perform simple tasks such as walking upstairs. An obese person gets tired very easily because the ankles and knees need to work twice as hard to be able to support his/her weight and may cause them to become sore and stiff. This could also harm the person’s posture, resulting in a hunched figure.
Genetics are a common risk factor to obesity, whether it is the amount of fat your stores and where it is distributed or how efficiently your body converts food into energy. The obesity gene affects one in ten people. However, it ultimately depends on your lifestyle and eating habits. Unhealthy eating patterns the most obese people tend to follow include a high-calorie diet, eating fast food, skipping breakfast, eating most of your calories at night, and eating oversized portions...

...e with the highest body mass index (BMI)—a measure of obesity—seemed to demonstrate a series of ‘fat habits’.” (via “7 Habits of Highly Obese People”) By working past these ‘fat habits’, obese people can rise up and overcome their weight issues. Andrew Lansley once said: “We must not constantly talk about tackling obesity and warning people about the negative consequences of obesity. Instead we must be positive- positive about the fun and benefits to be had from healthy living, trying to get rid of people’s excuses for being obese by tackling the issue in a positive way.”

The article “Fat and Happy: In Defense of Fat Acceptance” is written by Mary Ray Worley, a member of the National Association to Advance Fat Acceptance. She writes of her firsthand experience as a “fat person” in society. Throughout the article, Worley explains what it is like to be obese and describes the way society treats those who have a weight problem. She attacks the idea of dieting, criticizes medical professionals for displaying an obscured view of health risks, and defends the idea of exercising to feel good rather than exercising to lose weight. Unfortunately, her article seems to reflect only own opinions and emotions rather than actual facts and statistics.
This country places great value on achieving the perfect body. Americans strive to achieve thinness, but is that really necessary? In his article written in 1986 entitled “Fat and Happy?,” Hillel Schwartz claims that people who are obese are considered failures in life by fellow Americans. More specifically, he contends that those individuals with a less than perfect physique suffer not only disrespect, but they are also marginalized as a group. Just putting people on a diet to solve a serious weight problem is simply not enough, as they are more than likely to fail. Schwartz wants to convey to his audience that people who are in shape are the ones who make obese people feel horrible about themselves. Schwartz was compelled to write this essay,
What comes to your mind when you hear someone is overweight. In most american’s eyes, it is someone who anyone who is not a model. This creates a huge predicadment counting that America is known to be fat. In the past few decades, lifestyle has changed our habits, but we did not think about the consequences. If we eat more then we must be doing some kind of exercise to counteract what we put inside of us. In the article “America’s War on the Overnight” by Kate Dailey and Abby Ellin, they successfully persuade the reader to tackle obesity, we need to focus more on the subject of obesity and not attack the obese using the rhetorical triangle.
Obesity is a serious epidemic that majority of Americans face. The dangerous of obesity should not be taken lightly and addressed admittedly. However, the big question is how or why do some individuals stay skinny or become fat. The movie Weight of The Nations, Part 2: choice helps us explore this unanswered question to give us a better understanding of how this problem has gotten so out of control. This movie targets the obese society in America. This documentary uses scientist to research and address techniques to help people prevent weight gain and loss unhealthy weight. Most Americans want quick fixes to this problem, but have to realize big changes take time, but offer big results. Over all, the idea is to get people motivated by positive results to live a healthier live style.
Common causes of obesity can be excessive caloric intake, thyroid disorders, lack of physical activity, genes, medicines, emotions, smoking, age, and pregnancy. The combination of calorie restriction and exercise seems to be more effective rather than either one alone. Sticking to a weight
Although inherited conditions have been linked to childhood obesity, they are rare. However it has been noted that children with obese or overweight parents are more than likely to be obese themselves, the reason for this as described by Heaton-Harris (2007) is because of the length of time it takes to break a bad habit. Unless the parents are correctly informed of healthy diets themselves the problem will continue from an ill-informed childhood into adult hood. Other probable causes are numerous ones. Fast food and processed foods becoming more read...
Genetics plays a major role in obesity; inherited genes sometimes contribute to the accumulation of fat in the body. Over 200 genes have effect on the weight having repercussions from physical activity, food choices and metabolism. Therefore, genes may increase the vulnerability of a person to become obese. Family eating patterns and social tendencies can also trigger obesity. Moreover, environmental circumstances such as availability of food high in calories and fat and the increase of the portions and combination selections in meals contribute to the development of fat accumulated for years in the body (Whitney & Rolfes, 2011, pg. 277).
Obesity is when a person’s calorie intake exceeds one’s activity level. Activity burns calories and what ever calories are not burned, are stored as fat cells in the body. 19-24% is a healthy body mass index (BMI) for an individual. Mary Jo Thomas, M.D., states that “One that is obese has a body mass index of over 30. With a BMI of 30 or greater, one is at an immediate health threat.” (Thomas, 2013) Scientific evidence supports that the main causes of an obesity may include: ““increasingly sedentary lifestyle; high consumption of simple carbohydrates and fats (especially the refined sugars and greasy preparations common in junk and fast foods); and stress. To a lesser degree illnesses such as hypothyroidism (u...

Genetics play a significant role in obesity, since they increase a persons risk of gaining weight or developing excessive eating habits. “In a study of 226 families by Plymouth's Peninsula Medical School, researchers found that obese mothers were 10 times more likely to have obese daughters and for fathers and sons, there was a six-fold rise” (Medindia, 2009). The obesi...
As a health care professional it is our position statement that obesity should be considered as a disease. Overweight and obese adults are considered at risk for developing diseases such as type II diabetes, hypertension, high blood cholesterol, coronary heart disease, and certain type of cancers. An average of 300,000 deaths is associated with obesity and the total economic cost of obesity in U.S. was about $ 117 billion in 2000. As health care professionals it is our responsibility to increase public awareness of health consequences of over weight and obesity. Obesity as a disease: Obesity fits all the definitions of ‘disease’, that is, interruption in bodily function.
In a study from 2010, the CDC (Center for Disease Control and Prevention) found that the number one cause of death, killing 597,689 people each year, is heart disease. A major cause of heart disease is obesity, meaning that obesity kills many people in the united states each year. “In 1999-2000, 27.5% of men were obese, and by 2009-2010 the prevalence had increased to 35.5%” (Ogden, et al. 4). It is obvious that obesity is on the rise in our country. “the most recent national data on obesity prevalence among U.S. adults, adolescents, and children show that more than one third of adults and almost 17% of children and adolescents were obese in 2009-2010.” (Ogden, et al. 6). If the trends continue, obesity will become an epidemic, killing thousands of people. The CDC defines obesity as having a BMI (body mass index) of 30 or higher. In some instances, this can be misleading. For some people, say athletes that have plenty of muscle and not much body fat, their BMI can indicate they are overweight. Nevertheless, it is still a good indicator for the general public. And studies have shown, using the BMI system, that obesity in America is on the rise.
According to an article in Oxford Journals, “There is substantial evidence for the hereditability of obesity, and research in both rare and common forms of obesity has identified genes with significant roles in its etiology” (Genetics…).
“More than one third of America’s population is obese, which is about 35.4% including: men, women, and children” (www.cdc.gov). Unfortunately, this statistic is 100% true. America is hungry, constantly. This definitely shows that the land of liberty is growing in the midsection; no, not the Midwest, on the bellies of the people who live throughout the nation. America has a typical hierarchy of factors who rule the over the obese population. Junk food, lack of mobility, and undereducated knowledge of a healthy lifestyle, often contradict the fate of an obese person.
Obesity, also referred to as being overly overweight, is a condition caused when one eats excessive amounts of food leading to storing more calories than one burns. These calories are stored as fats1. Obesity can develop from several causes and is usually influenced by genetics.
