Dr. Jason Fung, MD, is a Toronto-based nephrologist and a world-leading expert in intermittent fasting and low-carb diets. He has written the bestselling health books: The Obesity Code, The Complete Guide to Fasting, The Diabetes Code, The Longevity Solution, Life in the Fasting Lane and The PCOS Plan.

Jason Fung, MD, born in 1973, received his medical training in Los Angeles and Toronto, specializing in nephrology. He established The Fasting Method (TheFastingMethod.com) to offer evidence-backed guidance on weight management and blood sugar control, emphasizing the benefits of low-carb diets and intermittent fasting.

It has become increasingly evident that traditional medical approaches are ineffective for many patients. Numerous chronic health issues today stem from dietary habits and obesity, yet treatments predominantly rely on pharmaceuticals and surgical interventions. Without addressing the underlying dietary factors, there is minimal improvement in the conditions. Therefore, resolving dietary issues necessitates dietary interventions.

Dr. Fung authored notable works such as The Obesity Code, The Complete Guide to Fasting, and The Diabetes Code. Additionally, he serves as the scientific editor for the Journal of Insulin Resistance and holds the position of managing director at the nonprofit organization Public Health Collaboration (Canada), which strives to disseminate reliable nutritional guidance globally.
