If you want to start a diet based on the Glycemic index or glycemic load principle this book is wonderful. FActs are explained in a very comprehensive way, other types of diets are mentioned and the reason why they don't work in the long run.
What I like about this book and what makes it different than the many other diet books in the market is its medical back up taken down to the layman's level.
There's a mention of the slow-carb revolution, hormonal balance, metabolism, dietary supplements and whether we need them, glycaemic load lists, the diet per se, a four week menu plan, good simple recipes and glycaemic load lists.
