Experts have long known there is a genetic component to obesity, and a new study identified one particular gene that may be behind it.

Researchers believe they have discovered a new biological mechanism for obesity, pointing to rare variants on two genes that dramatically increase the risk of carrying excess weight.

It turns out that obesity may be much more complicated than we thought, with the condition potentially existing in up to 11 ...

Obesity isn’t just a matter of food and exercise — it may be in your genetic code, according to new research.
