Nothing really revolutionary here. I have read of these suggestions elsewhere. However, the book pulls a lot of suggestions together and this is a contribution. The Foreword states the thesis (Page ix): ". . .overweight is a disease that can only be cured by restoring overall good health."
What does this mean? The author argues that we need to address two key causes--deficiency of needed nutrients and addressing ingestion of toxic materials. As Francis says (Page 1): "The weight is merely a symptom, and this symptom will come back unless you elimi8nate the underlying causes." The author argues that the standard American diet is the leading cause of disease--and obesity. What to do? Face off against "The Big Four": sugar, white flour, processed oils, and dairy/excess animal protein. Other bête noires: caffeine and alcohol.
What to do? Unprocessed fruits and vegetables; reduce animal protein; more fiber; organic, less treated foods (e.g., asparagus rather than bell peppers, since the former is less treated than the latter); more whole grain.
Tools? A diary or journal to outline what you actually eat as well as something like a written plan of action. One can then compare what s/he wants to do and what s/he actually is doing. In addition, chapter 13 provides a set of illustrative menus and recipes. Among recipes: veggie sandwiches, herbed hummus, meatless taco salad, vegetable wraps, spicy raw nuts, and veggie pesto pasta.
This book provides an approach to weight reduction that takes a somewhat different theoretical tack--albeit with many familiar operational dietary suggestions.
