By Jason Fung, MD

Dr. Jason Fung discusses the best fast lengths for you, including 16;8, Time Restricted Eating, 24 hour fasts, One Meal a Day (OMAD), 5:2 diet, extended fasting and more.

The best fast is the one that fits into your lifestyle. Fit your fasting into your lifestyle, don’t fit your lifestyle into fasting.
