Whether you're a diabetic trying to maintain your sugar level and weight, or overweight and trying to lose weight or just want to maintain good health, weight, and be fit this book is ideal for you. I am all of the above and got a lot of tips from it. I'm very excited about trying out what seems like a sure fire method of losing weight effortlessly. If there is a drawback I'd have to say, Dr. Colella, the author, has not paid attention to vegetarians.
