Details Condition: New Format: Paperback ISBN: 9781925228793 Publisher: Scribe UK Age Range: Adult Overview The Obesity Code by Dr Jason Fung is a groundbreaking, science-backed exploration of why diets fail and what really drives weight gain. Rather than blaming willpower, Fung presents compelling clinical evidence that hormones — specifically insulin — are the true root cause of obesity and related conditions like type 2 diabetes. Written in accessible language for general readers, this bestselling paperback reframes weight management as a solvable hormonal problem, offering a fresh, evidence-based path to lasting results rather than short-term, calorie-counting fixes. About the Book In The Obesity Code, nephrologist Dr Jason Fung draws on years of clinical experience treating patients with obesity, diabetes, and kidney disease to challenge the idea that weight gain is simply "calories in, calories out." Instead, he builds a research-supported case that chronically elevated insulin drives the body to store fat, and that reversing insulin resistance — not counting calories — is the key to sustainable weight loss. The book explains why popular diets fail long term, and how meal timing and food choice influence insulin far more than raw calorie totals. Fung introduces five practical, life-long eating principles for metabolic health, alongside a guide to intermittent fasting for breaking the insulin resistance cycle. Across 336 pages, the book blends physiology, clinical case studies, and dietary history into a persuasive, readable argument. It has become an international bestseller, praised for making endocrinology understandable while remaining rigorously referenced. Whether readers are managing their own weight or simply curious about nutrition science, this book offers a structured framework for understanding obesity from its hormonal roots.
