Nutrition and Metabolism

I have just put up a page on nutrition and metabolism – it is rather long (it is one of the appendices of a book that I am working on). It looks the various views of the nutrition world (Calories-In/Calories-Out “CICO” vs It’s-The-Insulin-Stupid “ITIS”), the latter being expressed in many of the modern diets (eg Atkins, GI, Southbeach, Zone, Paleo/Primal) and what they say about how to lose weight.
