I can't believe this book is even being sold by reputable book stores. Any "doctor" who would suggest in this day and age you go on a protein liquid diet is crazy. Not to mention the fact that he tells you to take laxitives the day before you start the diet. Is this man nuts. Don't waste your money, it's a 400 calorie per day liquid protein diet. He's actually selling his protein powder. What a hoax.
