The Genetics of Obesity
As a Biology major, the topic of the link between obesity and genetics is intriguing and worth researching. At 37 percent of adults, the prevalence of obesity in the American society is a phenomenon that would trigger any biologist to study bout it. This is why I chose to research on whether, besides the most common causes of obesity like over-eating and physical, genetics contribute a significant part of the prevalence percentage. Do individual genetics contribute a significant quotient to the level of prevalence of obesity in the American society, and if so, how much? (“National Institute of Health” 1).
It is popular to associate obesity to eating habits, and physical inactivity. I have experienced people being abused and made fun of for being obese. I personally had my own misunderstandings and decided to make a comprehensive research. While this may be a significant contributing factor, there are many other factors like Medications and Genetics. After a secondary material research, it became clear that an interaction between genetic and environmental dynamics generally catalyzes obesity. Changes in various genes that control metabolism and appetite predispose an individual to obesity under certain dietary conditions. A substantial percentage of obesity can be attributed to genetics.
The percentage varies widely, depending on the researched population, from 6 percent to 85 percent of the general prevalence. I held a misconception of associating obesity with eating habits and physical inactivity. However, I found out that there were many other dynamics involved to the phenomenon, thus its prevalence. I have received a wider view of obesity that has helped me to get rid of my biased understanding.
