Don't the hundreds of thousands of people who are 50, 100, 200, 300, etc pounds above their ideal weight disprove the 'preset weight range' theory?

Her argument, as I understand it, is that the weight has been going up because of the environment. That the environment is one in which we are able to "fully express" the full extent of our genetic predisposition for obesity.

This ties into her comparision to the heights of Americans during the Civil War and how it was so many inches below the average height today and that that is due to proper nutrition and thus the genetic predispostition to be tall can be fully expressed since there isn't starvation to stunt growth, just as there isn't starvation to halt weight gain.

That's what I got out of it anyway!
