Calorie information is ubiquitous. On packaged food, restaurant menus and online recipes we see authoritative numbers that tell us the calorie count of what we're about to consume. And we treat these numbers as gospel; counting, cutting, intermittently consuming and, if you believe some 'experts' out there, magically making them disappear. We all know, and governments advise, that losing weight is just a matter of burning more calories than we consume. Here's the thing, however, that most people have no idea about. ALL of the calorie counts that you see everywhere today, are WRONG. In Why Calories Don't Count Dr Giles Yeo, obesity researcher at Cambridge University, challenges the conventional model and demonstrates that all calories are not created equal. He addresses why popular diets succeed, at least in the short term, and why they ultimately fail, and what your environment has to do with your bodyweight. Once you understand that calories don't count, you can begin to make different decisions about how you choose to eat, learning what you really need to be counting instead. Practical, science-based and full of illuminating anecdotes, this is the most entertaining dietary advice you'll ever read.

'It is rare to find a book, written by a world-class scientist, that is both informative and entertaining. Giles not only delves into the science of obesity but, with honesty and great precision, skewers many of the more foolish fad diets out there. ' DR MICHAEL MOSLEY, bestselling author of The 8-Week Blood Sugar Diet 'A hard-to-fault book written in a way that entertains as well as it informs ... Yeo's study of human appetite is packed with insights and revelations, incorporating up-to-date scientific thinking ... It's an anti-diet diet book you can trust' DAILY EXPRESS 'I really enjoy working with Giles - he makes so much sense, and cuts through the confusion about diet and health with refreshing directness. His excellent book Gene Eating busts myths and homes in on what you really need need to know. It's been a genuine help to me and I'm sure it will be to everyone who reads it.' HUGH FEARNLEY-WHITTINGSTALL 'Dr Yeo is a leading scientist in the field of obesity and one of our best science communicators. Everyone worried about their weight ought to read this book to digest its message about the importance of genetics.' ROBERT PLOMIN, author of Blueprint: How DNA Makes Us Who We Are 'An excellent and engaging book, but also an important one. It is about time that a serious, respected academic provided a voice of reason' Anthony Warner aka THE ANGRY CHEF 'Gene Eating is just a fantastic book exactly as you'd expect - but more so. Mainly it's very funny, packed with science and trivia and genuinely helpful weightloss and nutrition info' DR CHRIS VAN TULLEKEN, the BBC Why are we all getting fatter? Why are some people hungrier than others? And why don't diets work? In an age of misinformation and pseudo-science, the world is getting fatter and the diet makers are getting richer. So how do we break this cycle that's killing us all? Drawing on the very latest science and his own genetic research at Cambridge University, Dr Giles Yeo has written the seminal 'anti-diet' diet book. Exploring the history of our food, debunking marketing nonsense and toxic diet advice, and confronting the advocates of 'clean eating', Dr Giles translates his pioneering research into an engaging, must-read study of the human appetite. Inspiring and revelatory, Gene Eating is an urgent and essential book that will empower us all with the facts we need to establish healthy relationships with food - and change the way we eat
