For many, losing weight is a never-ending struggle -- especially since our bodies are designed to keep weight on at all costs; it"s a matter of survival. But a medical revolution is under way, showing us how to work with our bodies instead of against them to ignite the natural fat-burning furnaces that lie dormant within us. Drawing on the cutting-edge science of nutrigenomics -- how food talks to our genes -- Dr. Mark Hyman has created a way of losing weight by eating the right foods, which in turn sends the right messages to our bodies. In this easy-to-follow eight-week plan based on each individual"s unique genetic needs, Dr. Hyman explains how to customize your personal weight-loss program with menus, recipes, shopping lists, and recommendations for supplements and exercise. Ultimately, you will rebalance and stabilize your metabolism -- an UltraMetabolism -- to maintain weight loss and enjoy lifelong health.
