This groundbreaking book by award-winning science writer and bestselling author of Why We Get Fat and The Case for Keto shows us that almost everything we believe about the nature of a healthy diet is wrong. "Gary Taubes is a brave and bold science journalist who does not accept conventional wisdom." --The New York Times For decades we have been taught that fat is bad for us, carbohydrates better, and that the key to a healthy weight is eating less and exercising more. Yet despite this advice, we have seen unprecedented epidemics of obesity and diabetes. Taubes argues that the problem lies in refined carbohydrates, like white flour, easily digested starches, and sugars, and that the key to good health is the kind of calories we take in, not the number. Called "a very important book," by Andrew Weil and "destined to change the way we think about food," by Michael Pollan, this groundbreaking book by award-winning science writer Gary Taubes shows us that almost everything we believe about the nature of a healthy diet is wrong.
