The book contains sample menus, more than 100 recipes, and suggestions on how to order in every kind of restaurant. Researchers have long known that carbohydrates cause the body to produce insulin and that high levels of insulin inhibit the breakdown of fatty deposits in the body. In contrast, low intake of carbohydrates keeps insulin levels low, forcing the production of a counterbalancing hormone, glucagon, which seeks energy from the body's supply of stored fat. Ergo, one loses weight. Not at all, attest the authors.
