A practical, accessible guide to understanding the diet myth and the secret to lasting weight loss. 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 the great myths of the body, and systematically explaining why dieting is counter-productive, this unflinching book investigates every aspect of nutrition. From the difference between good and bad fats to the impact of genes and genetic mutation on our weight and what happens to our hormones long after a diet ends, Dr Jenkinson explores the fields of agriculture, pharma, anthropology and medicine to uncover the truth behind our bad food habits and the escalating obesity crisis.
