I think AC nailed it on the head, here. So many of us hit LC after years of yoyo low fat dieting and our metabolisms can be pretty badly damaged.

Atkins (I haven't read Schwarzbein - yet) also agrees that eating high fat and low carb gives us a metabolic advantage so that in the absence of insulin, fat cannot be stored as fat.

But there is a caveat. If you eat too darn much of it, some of it will inevitably be stored as fat.

When I started, I figured I could eat just whatever I liked, when I liked. Didn't work that way. In fact, Dr A and SB (my latest read) both say to restrict to a point.

Is that any help?
