Dr. Jason Fung
MD · Nephrologist
World-leading expert on intermittent fasting and low-carb diets, focusing on insulin as the primary driver of obesity and metabolic disease.

Core Thesis
"Obesity is a hormonal disorder, not a caloric imbalance. Controlling insulin through fasting and carbohydrate restriction is the key to reversing metabolic syndrome."
The Fasting Protocol
Dr. Jason Fung shifted the medical paradigm from ‘calories in, calories out’ to the hormonal model of obesity. His protocols leverage the ancient practice of fasting to reset insulin sensitivity.
Key Protocols
- Intermittent fasting (16:8, OMAD)
- Extended therapeutic fasting
- Elimination of snacking to allow insulin levels to drop
