Based on twenty years of investigative reporting and interviews with a hundred practicing physicians who embrace the keto lifestyle as the best prescription for their patients' health, The Case for Keto 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. This book sets out to revolutionize how we think about eating healthy and what foods we can and can't eat to prevent and reverse both obesity and diabetes.
