Dr. Phil identifies seven reasons other diets fail: hunger, cravings, feeling of restriction, impracticality and expense, boredom, temptations, and disappointing results or plateaus. He addresses each of these roadblocks by applying the latest research and theories that have emerged since his last diet book 'The Ultimate Weight Solution.' In his new diet, readers start by eating only 20 key ingredients, called the 20/20 Foods, which include coconut oil, green tea, almonds, apples, chickpeas, prunes, natural peanut butter, nonfat yogurt, eggs, raisins, codfish, whole-grain rye products and whey protein, foods which may enhance your body's thermogenesis and help you feel full. Thermogenic foods are those that make your body invest a high amount of its stored calories just to digest them. That's just the beginning. This book explains why you haven't been able to lose the weight before, and empowers you with cognitive, behavioral, environmental, social and nutritional tools so you can finally reach your goal, and learn lifelong healthy habits to maintain those results.
