Dr. Mark Hyman, MD
Functional Medicine Physician, Author
Dr. Mark Hyman is a functional medicine physician and Director of the Cleveland Clinic Center for Functional Medicine whose work reframes food as hormonal medicine rather than a collection of macros. His research on blood sugar regulation, ultra-processed food, and metabolic root-cause medicine directly supports the RealFoods thesis that insulin control, not calorie restriction, is the lever that determines whether the body stores or burns fat. His work is especially relevant for people managing type 2 diabetes or supporting a family member with the condition.
