'Obese but Happy Gene' Challenges the Common Perception of Link Between Depression and Obesity

Not exactly.

Researchers at McMaster University have discovered new genetic evidence about why some people are happier than others.

McMaster scientists have uncovered evidence that the gene FTO -- the major genetic contributor to obesity -- is associated with an eight per cent reduction in the risk of depression. In other words, it's not just an obesity gene but a "happy gene" as well.

Happy for Type 2 diabetes, cardiovascular disease, obstructive sleep apnea, etc.

Really:

'Obese and Stupid Gene' confirms the Link Between Cluelessness and Obesity.

Clearly.
