The “short” version could almost be called the “affirmative action” diet — that is, no “whites” (except for egg whites):
No sugar, white flour (bread, pasta, cake) or white rice.
That sounded impossible, but for whatever reason, reading the book and buying the stuff on the grocery list (very important) helped me get my mind right.
I haven’t followed the book slavishly. For instance, its particular exercise program is just too hard and weird for me.
So now I have another ten pounds to go.
(According to every source I’ve ever read, I’m supposed to weigh around 100 pounds, and while I used to weigh that — and less — I don’t think that is realistic.)
