Jason Fung, MD, turned his passion for disease prevention into a groundbreaking, clinically proven, and natural treatment for type 2 diabetes and obesity that has helped thousands of people around the world lose weight and reverse and prevent metabolic disease. Often called the founder of intermittent fasting, Dr. Fung was one of the first medical doctors to prescribe a lowcarb, high healthy fat diet alongside intermittent fasting to his patients struggling with diabetes and obesity. Today, Dr. Fung continues to promote the fasting lifestyle while simultaneously addressing the root causes of hunger and overeating in his patients.
Dr. Fung completed medical school at the University of Toronto and a fellowship in nephrology (kidney medicine) at University of California, Los Angeles before going on to practice nephrology in Toronto. Dr. Fung is also the co-founder of The Fasting Method, a program that helps patients lose weight and reverse their type 2 diabetes naturally.
As a young nephrologist (kidney doctor) working with patients whose type 2 diabetes had led to kidney disease, Dr. Fung saw a clear relationship between prescribed insulin medication and weight gain, an observation that led him to intermittent fasting as a way to lower insulin and force the body to burn fat as energy. Today, Dr. Fung has prescribed intermittent fasting and a low-carb diet to thousands of patients. They have seen results that include reversal of type 2 diabetes, weight loss, and an overall higher quality of life and wellbeing.
In 2016, Dr. Fung published one of the first popular science books to recommend intermittent fasting for weight loss, The Obesity Code, which went on to sell over 2 million copies worldwide. Next he published The Diabetes Code, which lays out his foundational approach to type 2 diabetes prevention and reversal. A New York Times-bestselling author, Dr. Fung has written and contributed to numerous other books on disease prevention, including The PCOS Plan, Life in the Fasting Lane, The Cancer Code, and the follow-up to The Obesity Code, The Hunger Code.
