An early proponent of the now-popular fasting lifestyle, Dr. Fung is often called the founder of intermittent fasting and is regularly “cited to provide scientific legitimacy for a diet that can seem outlandish to the unfamiliar” (Quartz).

His books, including “The Obesity Code,” “The Complete Guide to Fasting,” “The Diabetes Code,” and “The Cancer Code,” have challenged conventional thinking about these diseases and introduced dietary strategies to manage them.

He is the co-founder of The Fasting Method, which provides the education, tools, and community needed to successfully implement intermittent fasting.
