Since 1986 I have read many books and listened to many teachers all of whom I learned from. By far Andreas Moritz is the best -- he has all the puzzle pieces and a calm, natural way to share with us the real truths about how our bodies work and what they need to be healthy and achieve our correct body weight. I bought and have read several other of his books and would highly recommend them also including Timeless Secrets of Health & Rejuvenation (The "Big Book" reference manual for your life), Cancer is Not a Disease (everyone should read - especially anyone with a diagnosed "disease" of any kind not just cancer), and the Amazing Liver/Gallbladder Cleanse. I cannot recommend his books enough. Lightbulbs on anyone?
