A large number of people believe that obesity is genetic. However, this is proven to be false. Obesity is a worldwide problem in America. Believing that obesity is generic kills hopes for those who were motivated to lose weight- this is why it is to important to let America know the truth. Research on human obesity genes started several decades ago. Advances in biology and the Human Genome has helped this research. This research has illuminated many genetic factors responsible for obesity.
Genetic changes does not explain obesity because the gene pool has remained stable for many generations. It takes a very long time for a new mutation to spread. Therefore, since or genes have not changed for years, the other thing that has changed is our environment and habits. The environment has influenced what to eat, how much and how active we are. Back then, people were much more active using walking or bicycles as transportation compared to this generation. In our current generation, no barely ever anyone using active transportation- almost every person owns a car. Other environmental changes that promotes obesity is how easy it is to overeat, for example- fast food places or drive through.
Research and studies have shown that genetic susceptibility to obesity can be changed by life choices such as exercising. We can control how much we eat or exercise. Regardless of how obese your parents are, the child can prevent obesity by a healthy diet and exercise. Americans should not point the finger at thier genes but rather blame self-control.

I completely agree with you that the environment in our generation today has a large impact on the obesity rate today. Like you stated, it is very common for everyone to have a car to use to get from point A to point B, and it is very likely that they will pass several fast food places along the way. However, I did think that obesity was genetic as well, but I do believe that our surroundings play a larger part in the amount we weight and whether or not we become obese.
ReplyDeleteI really like this post. I agree that genes are not the only reason people become obese. With so many studies coming out blaming genes for everything, our genetic makeup has become an excuse. Our environment, diet, and exercise have a big influence on our weight. Yes, genes may play a part in our bodily health but our lifestyle also effects us very heavily.
