"What If It's All Been a Big Fat Lie?" Are we doomed to be obese because of heredity, and is the argument of this article still valid today?

Judging by the evidence of this article, I don't believe heredity plays a huge role. The author mentioned that there is no way of testing for this gene and also that if the problem was something other than obesity, say anorexia, people would blame a gene for that too. The point is, while a gene to cause obesity probably exists, it is mostly used as an excuse for an explanation to our problem.

The argument of this paper may no longer be valid with today's food system, because of the changes that have occured since it was written in 2002. Nowadays, advertisements for fast food and other restaurants dominate television, and these types of foods could play a bigger part in the diets of the average American. The article asserts that carbs, not fats, are responsible for the obesity in this country, but with the excess amount of fatty food and advertisements for that food, it is nearly impossible to tell.
