I'm starting on Week Four, after having read this book, and can only say: it's simple, it works and I'm loving it. The book is easy to understand, it's clear and helpful. The lifestyle diet, most importantly, is simple to adhere to and I'm losing weight. I even stuck to it in Florida on a vacation! In fact, my mother watched me eating on this diet and said "I can't believe you can actually lose weight eating that much food." But I did and I am! I find the book to be encouraging and realistic and it certainly does help to understand WHY certain things will assist in the weight loss process. The author treats the reader like an adult and assumes one can understand the ins and outs of nutrition and explains it in-depth but with humor, clarity and encouragement. I don't love the crackers but then again, there is so much food containing fiber that it's not entirely necessary to eat them in order to remain on the diet. I think the reviewer who said that there are a lot of product endorsements is being ridiculous. Readers need and want clear ideas as to how to stay on this healthy lifestyle plan and the author gives them. Try this. You won't be sorry and you'll feel great doing it. I promise.
