Genetic Flaw May Be Linked With Some Cases of Obesity

GenesBlaming people for their obesity is no longer appropriate given the number of studies that point to the genetic influence underlying many cases of obesity. The researchers say it’s likely that a “patchwork” of different genetic variations will eventually emerge to explain more cases of obesity.  These genetic flaws may result in obesity by affecting appetite, or the rate at which the body burns fat.

That being said, most of the obesity epidemic currently affecting most Western countries still is attributed to a trend towards high-calorie foods and more sedentary lifestyles.
