The Fast 800

The Fast 800 was developed by Dr Michael Mosley and a team of doctors and weight loss experts. Our programme, and range of health support products, including meal replacement shakes, help people lose weight, stay healthy and live longer. Dr Mosley was committed to using scientific evidence to help people lose weight for better health – not just a “better” body. This foundation means The Fast 800 is rooted in methods that enable long-term weight loss and better health outcomes. We have proudly supported tens of thousands of people achieve just that, and will continue to honour Dr Mosley’s legacy to help more people into the future.
