Inspired by his best friend’s battle with cancer and drawing on his years of experience as a physician and the VitalityPro research protocols that he developed with iconic athletes, elite sports programs, respected nutritionists, and behavioral and exercise psychologists, Dr. Frank Merritt has engineered a unique protocol that delivers all the benefits of fasting in a minimum effective dose. Following the protocol outlined in The 17-Hour Fast just once a week can deliver performance and health benefits to anyone, from high achievers and athletes to first responders and military personnel to everyday folks. The 17-Hour Fast is founded on a bedrock of cutting-edge scientific data and presented in an intuitive and approachable way by Dr. Merritt and acclaimed writer Phil White (Unplugged, Game Changer, and Flight Plan).
