FROM NEW YORK TIMES BESTSELLING AUTHOR DR. JASON FUNG

"An important and timely book. Highly recommended."—Dr. Mark Hyman

In The Diabetes Code, world-renowned nephrologist and metabolic health expert Dr. Jason Fung reveals a bold, science-backed approach to preventing and reversing type 2 diabetes—without relying solely on medications, extreme calorie restriction, or complicated meal plans.

Drawing on cutting-edge research in metabolic health, insulin resistance, and intermittent fasting, Dr. Fung explains how type 2 diabetes is not a chronic, progressive disease you’re doomed to manage for life—but a reversible condition rooted in one key hormone: insulin. By addressing the true cause of blood sugar dysfunction, you can reclaim your health, stabilize your weight, and dramatically reduce your risk of heart disease, stroke, and other complications.

This eye-opening book is perfect for anyone searching for:


Natural ways to lower blood sugar and improve insulin sensitivity
A sustainable plan for diabetes prevention and reversal
Evidence-based strategies for natural weight loss and long-term weight maintenance
A clear, practical guide to low-carb living, intermittent fasting, and metabolic flexibility


Inside The Diabetes Code, you’ll discover:


Why most conventional treatments for type 2 diabetes fail to fix the real problem
The critical link between obesity, metabolic syndrome, and insulin resistance
How fasting protocols and low-carbohydrate, whole-food nutrition can reset your metabolism
Simple, step-by-step strategies to improve blood sugar control without feeling deprived
How to work with your healthcare provider as you implement a science-backed diabetes reversal plan


Accessible, empowering, and rooted in the latest medical research, The Diabetes Code offers a clear path toward:


Better metabolic health
Reversal of type 2 diabetes for many patients
Sustainable, natural weight loss and improved energy
Long-term protection against chronic disease


If you’re frustrated with yo-yo diets, rising A1C levels, or an ever-growing list of prescriptions, this book will help you finally understand what’s going wrong—and how to fix it.
