Our story
We are a group of doctors and health professionals who grew frustrated with the increasing gap between what has long been widely accepted as “healthy eating” and the latest evidence on what actually works.
Based on some of the most promising and studied areas of research, we developed The Fast 800 online programme and The Fast 800 shakes, which are designed to help people lose weight, stay healthy and live longer.
