I have the book and the first 100 pages are the hows, whys, of this "diet". The other pages are all menus and excellent recipes. My suggestion is to buy the book if you can.
I don't like to use the word "diet". I'm not following this plan to a T. The main thing that I think everyone needs to do - whether or not they follow this plan or not - is to stop eating carboyhydrates that have no nutritional value whatsoever. These kinds of carbs would include cake, cookies, pies, chips, etc. Cut way back on white potatoes, white rice, white pasta, etc. Eat more vegetables, fibrous foods, whole wheat bread, brown rice, sugar-free low-fat yogurt. Try to learn a bit about foods based on the glycemic guide.
This plan does not allow fruits for the first 2 weeks. I don't agree with that at all. I suppose you could say I'm following this plan by simply eliminating some of the foods I have listed above.
