We all know someone who seems to eat very little yet cannot avoid weight gain, or someone who eats everything they like while remaining slim. Why? Is it the kinds of food we eat, and when? Are our hormones to blame? In this book, Keith Frayn, one of the world's leading experts on metabolism, argues that all these challenges are distracting us from tackling the obesity problem in the only way it can be addressed: by rebalancing the disregarded message of 'calories in - calories out'.

In this game-changing book, Keith Frayn, an international expert in human metabolism and nutrition, dispels common misconceptions about human metabolism, explaining in everyday language the important metabolic processes that underlie all aspects of our daily lives. Frayn describes the communication systems that enable our different organs and tissues to cooperate, for instance in providing fuel to our muscles when we exercise, and in preserving our tissues during fasting.
