The Diabetes Code: Prevent and Reverse Type 2 Diabetes Naturally

FROM NEW YORK TIMES BESTSELLING AUTHOR DR. JASON FUNG—the physician widely credited with popularizing intermittent fasting for weight loss—comes the groundbreaking, science-backed guide to preventing and reversing type 2 diabetes naturally.

"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.
