I agree. I was hungry at first and worried about calories, but lately I've had a difficult time eating much at all. The reason is that I'm not hungry much anymore and I'm basically too lazy to cook in spite of it. I keep my carbs pretty low though.

When (if) I start upping my carbs I'll have to start worrying about the effects of insulin, and carbs make me hungrier on top of that. If eating until I'm full makes me start gaining, I'd take that as a sign that my carb limit has been exceeded. I think what Dr. Atkins is recognizing here is that teaching yourself to eat less doesn't work in the long run, but if you find the right balance of fats/carbs it won't be an issue anymore.
