Causes & Effects of Obesity- Listening and note taking lesson

An individual’s weight arises from a balance – between calories taken in versus calories burned by physical activity. If an equilibrium is maintained between these two, then an individual can maintain appropriate body weight. If an equilibrium is not maintained, weight is either gained or lost. Obesity occurs with caloric disequilibrium of such an extent that the person’s weight is far above the ideal body weight. Obesity has become a major problem in many countries. Experts predict that in the United States average life expectancy will soon drop for the first time in 200 years due to the obesity epidemic. Understanding the causes and effects of obesity is a step to reversing the trend. Diet, genetics, and age are the three main factors that contribute to obesity. People nowadays eat high-carbohydrate, high-fat burgers and pizza in fast-food restaurants, which results in their intake of excessive calories. Over time, overeating will lead to weight gain and may bring about obesity, especially if the diet is rich in fats. Foods high in sugar and fat as well as fried food promote the deposition of fat in the body, ultimately leading to obesity. Overeating of unhealthy foods is often due to boredom, anger, or stress – emotions brought about by our modern lifestyle. Some cases of obesity are brought about by genetic factors. If a child was born into a family whose members are overweight, then the child may end up being obese. Age is also a factor in weight gain. As people get older, they tend to lose muscle, especially if they are less active. Muscle loss can result in the body slowing down the rate at which it burns calories. Diet, genetics and age are factors in weight gain and later obesity, the results of which are devastating. Obesity is a serious, chronic disease that can have a negative effect on many systems in the body. Many health issues can develop from obesity. Obesity is the major cause of diabetes. The majority of obese people acquire Type 2 Diabetes as they reach adulthood because obesity interrupts the functioning of the hormone insulin in the body. This hormone helps regulate blood sugar in the body. Moreover, people who are obese usually have high blood pressure, and this in turn can lead to decreased life expectancy. Heart diseases can also stem from obesity. Obesity has social consequences. Lack of self-esteem can be caused by obesity, and this can lead to depression and eating disorders.
