This book really made it much clearer for me: <a href="http:&#x2F;&#x2F;www.amazon.com&#x2F;The-Enzyme-Factor-Hiromi-Shinya&#x2F;dp&#x2F;0982290039" rel="nofollow">http:&#x2F;&#x2F;www.amazon.com&#x2F;The-Enzyme-Factor-Hiromi-Shinya&#x2F;dp&#x2F;098...</a><p>Advise of a doctor called Hiromi Shinya, who studied&#x2F;observed intestines all his live. He is one of the best in his field and the explanations he gives in his book are really really logic and inspirational. I highly recommend it, it changed my perspective of food. Counting calories never done it for me. Not all calories are not the same.<p>Hiromi Shinya also made it clear that we only think about our outside and not about. The inside and the inside is all what counts to stay healthy and live a long live. You can be thin and extremely unhealthy. It is the inside what counts and we shouldn&#x27;t exhaust our organs.
