Overall, this book was disappointing. The book starts off well, promising to identify one's type of sugar addiction and then offer solutions. There are some good points made, and things I will follow-up on. However, in its efforts to be a gimmicky "workbook", the book shortchanges the readers on important details and specifics. Just a few examples: in the discussion of sugar alcohols, there is absolutely no mention of xylitol, which is probably one of the most widely used sugar alcohols in the world (particularly in the Scandinavian countries) and readily available in North America. There is no mention in the book of vegetarian diets, leaving some of us mystified as to how to modify his prescriptions for meat, fish, eggs, and seafood (and of course, I'm not even mentioning the extremely well-documented negative health consequences of the amount of animal products he suggests, including the effects of excess protein). He does not discuss the effect of polished white rice on the body, which in my limited understanding acts in a way similar to white sugar and white flour.
Some of his discussions are simplistic. When describing how walking burns calories, he uses a straight one-to-one ratio, without clearly explaining how exercise (or the lack of it) changes one's metabolic rate, thus producing a multiplier effect on calorie burning. And his prescription to "eat more salt" left me dumbfounded. Yes, individuals react to sodium differently, but such blanket advice is simply dangerous.
Furthermore, and without comment on the products' merits, the book is suffused with not-so-subtle advertisements for various products sold or promoted by the author. A simple disclaimer (something to the effect of "I sell and/or have a financial interest in these products" would have helped the author's credibility).
I was left with the overall impression that I did not have the information I needed about this important problem. Based on his quizes, I was not even able to concretely identify my type of sugar addiction. In fairness, the book may have been simplified for the mass market. Still, I would recommend that you get this book from your local library and skim it before you purchase.
