The causes of obesity
Causes of Obesity Obesity attacks over half people in America. Obesity occurs when a person weight is above its ideal body weight, and this is a major problem in America. Consequently; Genetic, lack of awareness, and lack of exercise are the main causes of obesity. Genetic, is one of the most important causes of obesity. A resent study had show that gene controls body composition by regulating metabolism. During the study scientists had two sets of mince for experimentation. They found out that the problem was the IRX-3 which is a member of the Iroquois homeobox gene family and plays a role in an early step of natural development.
While the first set was normal, the second was engineered without the IRX-3 gene. Both sets ate the same diet and we’re exposed to the same exercise. Finally, scientists conclude that those mice without the gene weighed 30 percent less than those with it, due to a reduced amount of fat in their bodies. They were also found to be resistant to obesity as well as diabetes, and burned energy more efficiently. This example explains clearly how genetic affect humans. Other important cause of obesity is lack of awareness. Nawdays, many people don’t have good habits they don’t see what they eat they don’t even care about it.
That’s why a lot of people eat everytime more junk food and fast food. This food Is high in fat and cholesterol. People who eat frequently junk food are more prone to suffer heart attacks. Most of the time people who work more than 10 hours they don’t have time for cook or go home and eat something healthy , so they buy something easy such as fast food. The bad habits of these people come since their childhood, and parents are the responsible for these bad habits because they don’t measure food portions that they give to their children. Another cause of obesity is lack of exercise.
Lifestyle in America is very different from other countries. For example, in Mexico people tend to walk wherever they go. However, in America people can’t go anywhere if they don’t have a car. Another example is when people work a lot and they don’t have time to do exercise, so when they come home they want to relax and take a rest. In short, genetic , lack of awareness and lack of exercise are three important causes of obesity. As a suggestion , if people don’t take care of their weight, they will have serious problems due to obesity in a short time.
