Building upon his critical work in Good Calories, Bad Calories and presenting fresh evidence for his claim, Gary Taubes revisits the urgent question of whatâ€™s making us fatâ€”and how we can change.Â He reveals the bad nutritional science of the last centuryâ€”none more damaging or misguided than the â€ścalories-in, calories-outâ€ť model of why we get fatâ€”and the good science that has been ignored. 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? Persuasive, straightforward, and practical, Why We Get Fat is an essential guide to nutrition and weight management.
