Tim Spector, one of the leading scientists in the field, reveals the extraordinary connection between our gut and our health'Completely fascinating' Sheila Dillon'A great book . . . very convincing' Alex Renton, BBC RADIO 4'The Diet Myth is fascinating, and I'm now obsessed with microbes!' Nigella LawsonFULLY REVISED AND UPDATED EDITIONWhy do most diets fail? Why does one person eat a certain meal and gain weight, while another eating the same meal loses pounds? Why, despite all the advice about what to eat, are we all still getting fatter?The answers are much more surprising - and fascinating - than we've been led to believe. The key to health and weight loss lies not in the latest fad diet, nor even in the simple mantra of 'eat less, exercise more', but in the microbes already inside us.Drawing on the latest science and his own pioneering research, Professor Tim Spector demystifies the common misconceptions about fat, calories, vitamins and nutrients. Only by understanding what makes our own personal microbes tick can we overcome the confusion of modern nutrition and achieve a healthy gut and a healthy body.THE FOOD PROGRAMME (BBC RADIO 4) BOOK OF THE YEAR'I don't read diet books and I certainly never plug them, but The Diet Myth is a worthy exception that provides new insight into why we should think twice about what we put in our mouths' The Times'Ground-breaking' Bee WilsonSee what readers have to say:'If you read one book about diet and your health, this should definitely be it' 'This book is an absorbing read; a clear explanation, in layman's language, of why diets so often don't work' 'Very rarely do I come across a book so valuable I feel compelled to by again and again.
