familiar with the "Zone Diet", a book that came out about 15 years ago. I read it an came away impressed in that there seemed to be real science behind it. It explained how the body deals with different types of food. Not just proteine, fat and carbs, but got into the bio-chemistry of how the body deals with different types of carbs and different types of fat and how there is an ideal ration to maximize weight loss during a diet and subsequent daily living. I am sure it is this very same thing you are speaking of, on how athletes need to closely monitor what they take in. Are you familiar with Onwalu and the guy that trains the Cretin Durham kids ? Is he more along the lines of nutritionsists you speak of ? I know he is a trainer, but since James is so into his diet, I am assuming this trainer is also the same guy guiding him with nutrition. Thanks.
