If you've been a yo-yo dieter for years or if you can eat a pound of pasta at one sitting, this book may very well be an eye opener. In simple--but never condescending--language, it explains the roots of carbohydrate cravings and teaches you how to normalize your insulin levels to prevent future food binges. Regulated insulin levels in turn help to temper serotonin levels, so food cravings and mood swings are prevented. The authors, both research scientists (one a health psychologist, the other a pathologist), have lost and kept off a total of 200 pounds between them. They've based this book on nearly a decade's worth of research, during which they've helped nearly 80 percent of their patients lose weight and keep it off for at least a year. They explain that carbohydrate addicts most commonly crave popcorn, breads, bagels, rice, pasta, potatoes, ice cream, chocolate, pie, cookies, crackers, cake, fruit and fruit juice, potato chips, and pretzels. A questionnaire at the beginning of the book determines if you're indeed a carbohydrate addict, and if so, to what extent. (For those readers whose quiz doesn't indicate addiction, but who are bothered by their food cravings, the authors recommend a doctor's visit for an explanation.) The book includes a diet plan with dozens of easy recipes, a chart of the carbohydrate content of many common foods, and lists of binge triggers to watch for. The most appealing part of the diet--and one reason that it wins raves from its followers--is its once-a-day reward meal, which allows you to eat anything you want. The authors also offer helpful tips for incorporating the diet away from home, such as at parties and restaurants.
