Obesity Causes example essay topic

The Increasing Battle against Obesity Obesity is a disease that affects nearly one-third of the adult American population, or approximately 60 million Americans. The number of overweight and obese Americans has continued to increase since 1960, a trend that shows no sign of subsidence. Today, 64.5 percent, or about 127 million adult Americans are categorized as being overweight or obese. Each year, obesity causes at least 300,000 excess deaths in the U.S., and healthcare costs of American adults with obesity amount to approximately $100 billion.

Obesity is characterized by increased body weight and is caused by the excessive accumulation of fat. By taking in more calories than are burned on a daily basis, the excess is then stored in your body as fat. Doctors and scientist generally agree that men with more than 25 percent of body fat and women with more than 30 percent of body fat are considered to be overweight. However, it is difficult to measure body fat precisely. The body mass index (BMI) has become the most common method used in medical standard today. Among several factors such as diet and exercise, there are five main causes that contribute to the growing number of obese people in America: environmental factors, psychological factors, genetic or hereditary factors, underlying physical factors, and medication factors.

Our environment plays a huge part in many cases of obesity. Environmental factors include lifestyle behaviors such as what and how much a person eats and how active they tend to be. As a society America falls into the high fat, low exercise category. Many overweight or obese people use the excuse that they simply do not have enough time to eat right or cook nutritional meals.

They eat whatever is fast and convenient. As for exercise, the same excuses apply. This unhealthy behavior that is influenced and characterized by society today ultimately leads to the apathetic approach to a healthy lifestyle. There are psychological factors that may influence eating habits as well. Many people eat during times of boredom, sadness, anger, depression, and other negative emotions. Over time, the association between emotion and food can become firmly fixed.

Depression and stress can lead to obesity and are also leading causes of eating disorders. Undeniably, most eating disorders can be traced to behavioral or psychological difficulties. Contrary to popular myth, this does not indicate weakness or lack of will power. However, it does lead to mental or physical problems, which can lead to binging or overeating. Obesity tends to run in families, suggesting genetic factors. It is complicated to find the "obesity gene" because families tend to share eating and lifestyle habits, making it difficult to separate genetics from behavior.

It's estimated that if both parents are obese, a child has an 80 percent chance of also being obese. If one parent is obese, the odds drop to 40 percent. If neither parent is obese, the probability is about 10 percent. Some people simply inherit more and larger fat cells and have the unfortunate ability to store what they eat more quickly as fat. Obesity is caused by underlying factors as well.

Certain physical disorders can lead to overeating or can even interfere with the body's mechanism that regulates calorie use. Conditions such as hypothyroidism and hypothalamus can lead to weight gain due to the interference with proper calorie intake. Hormones also play a distinct role in obesity. When full, fat cells release the hormone Leptin, which suppresses appetite and ends the feeling of hunger. When the production of this hormone is hindered, fat cells are unable to signal that they " re full and weight gain occurs. As an inadvertent culprit to weight gain, certain medications can cause unwanted fat storage.

Steroid medications and some antidepressants also list weight gain as a potential side effect. Overall, research has shown that obesity is not only caused by overeating. Underlying factors as well as proper diet and exercise give us the answer to why we gain so much weight. Such factors have shown to increase the potential for weight gain and the tendency to reach obesity. As well as being its own risk, obesity can increase one's risk of developing conditions such as high blood pressure, diabetes, heart attack, stoke, and certain kinds of cancer. By eating healthy and maintaining a positive lifestyle, this devastating disease can ultimately be avoided.

People can't change their genetic make-up, but they can change their eating and exercise habits..
