‘This could – should – be the last diet book you will need. It’s colourful, readable, personable, richly informed, expert and just, well… right’ James McConnachie, Sunday Times

Why is it so hard to decide what to eat? We are bombarded with conflicting advice on weight and health, fad diets and food pyramids. No wonder so many of us feel confused and guilty.

In Fed Up, Daniel Lieberman tackles this confusion head on with his trademark blend of lively storytelling and myth-busting science. Drawing on evolutionary biology, anthropology and physiology, he explains how humans first evolved to eat; how fire, farming and industrialization transformed our diets; and what that history combined with rigorous medical science can – and cannot – tell us about what to eat today to stay healthy and manage our weight. In each chapter, Lieberman explores what different diets – from Paleo to veganism to intermittent fasting – tell us about nutrition and health, even putting these diets to the test himself. His conclusion is liberating: there is no optimal diet. What matters instead is variety, moderation and finding out what works for you.

Clear-eyed, humane and always entertaining, Fed Up gives us the tools to make wiser, kinder choices about what we eat.
