We've all heard the golden rule: eat less, exercise more and you'll lose weight. But what if it isn't that simple?

For over two decades, weight loss surgeon Dr Andrew Jenkinson has treated thousands of people who have become trapped in the endless cycle of dieting. Why We Eat (Too Much), combines case studies from his practice and the new science of metabolism to illuminate how our appetite really works.

Debunking myths of about body and systematically explaining why dieting is counter-productive, this unflinching book investigates every aspect of nutrition: from the 'set weight point' that is unique to all of us, to good and bad fats, and from how genes impact our weight to how our hormones are affected after a diet ends.

With a new chapter about the link between obesity and COVID-19, this incredible book will help you understand your body better than ever before.
