Definition Of Obesity Gene

The genes which were once beneficial to our ancestors during food shortages are now liabilities in today s environment of food excess.

Definition of obesity gene. Obesity is the result of chronic energy imbalance in a person who consistently takes in more calories from food and drink than are needed to power their body s metabolic and physical functions. The risk of obesity is determined by not only specific genotypes but also gene gene interactions. The modernization of our society has contributed to higher rates of obesity through an environment that promotes increased calorie intake and decreased physical. The rapidly rising population prevalence of obesity in recent decades has been attributed to an obesogenic environment which offers ready access to high calorie foods but limits opportunities.

Obesity definition obesity is an abnormal accumulation of body fat usually 20 or more over an individual s ideal body weight. The fat mass and obesity associated gene fto was the first obesity risk gene identified by genome wide association studies. To date over 50 obesity risk genes have been identified. However there are still challenges associated with detecting gene gene interactions for obesity.

The branch of medicine that deals with the study and treatment of obesity is known as bariatrics. Obesity is associated with increased risk of illness disability and death.
