This book has been a godsend for me. I am one of those very frustrated people who gains weight on the low-fat, high carbohydrate diets being touted by today's nutrition experts. This book did a great job of explaining why this was happening. After one week on the protein power diet, I have lost 4 pounds and have more energy. As a bonus, the chronic heartburn that I have suffered with for years stopped on my second day on the plan! I can't recommend this book highly enough.
