"For years health organizations have preached the same rules for losing weight: restrict your calories, eat less, exercise more. It's simple enough. So why doesn't it work for millions of overweight or obese Americans? Gary Taubes sets the record straight--clarifying a century of misunderstanding about the differences between diet, weight control, and health--and gives us a revolutionary manifesto for the 21st-century diet, and a primer on how low-carbohydrate, high-fat/ketogenic diets can help you achieve and maintain a healthy weight for life. Taubes's book puts the ketogenic diet movement in the necessary historical and scientific perspective. It makes clear the vital misconceptions in how we've come to think about obesity and diet (no, people do not become fat simply because they eat too much; hormones play the critical role) and uses the collected clinical experience of the medical community to provide essential practical advice"-- Provided by publisher.
