Taubes reveals the bad nutritional science of the last century, none more damaging or misguided than the "calories-in, calories-out" model of why we get fat, and the good science that has been ignored, especially regarding insulin's regulation of our fat tissue. He also answers the most persistent questions: Why are some people thin and others fat? What roles do exercise and genetics play in our weight? What foods should we eat, and what foods should we avoid? Packed with essential information and concluding with an easy-to-follow diet, Why We Get Fat is an invaluable key in our understanding of an international epidemic and a guide to what each of us can do about it.
