The Obesity Gene

Is there really an obesity gene? I think the answer is yes and no.  First the yes.

There are likely genes that predispose someone to being overweight or obese.  It is not just one gene but perhaps 10 or 50, or maybe 1,000.  I don’t think we will ever be able to say for certain what specific genes are the “obesity genes.” Certainly it is more difficult with something like this because metabolism is so complex.

The answer to our question might also be no.  While our genes are responsible for many things, the environment plays a huge role.  Diet and exercise are potent modifiers of our genes.  Someone who is genetically predisposed to being overweight may not be overweight with proper diet and exercise.  And if that’s true then, in a sense, being overweight is not genetic.
