Are you fat and happy? (If you’re NOT happy about being fat, you need Anne Strieber’s famous diet book!) Scientists have discovered that the major genetic contributor to obesity is also associated with an 8% reduction in depression. In other words, it’s both a "fat gene" and a "happy gene."
This study challenges the common perception of a reciprocal link between depression and obesity: That obese people become depressed because of their appearance and social and economic discrimination; depressed individuals may lead less active lifestyles and change eating habits to cope with depression that causes them to become obese.
Researcher David Meyre says, "We set out to follow a different path, starting from the hypothesis that both depression and obesity deal with brain activity. We hypothesized that obesity genes may be linked to depression."
