Working with Dr Michael Mosley, we use the latest scientific research to create a game-changing approach to weight loss and healthy living.
Through a 12-week supported programme, an ongoing monthly subscription, an engaging community and a range of products to support your journey, The Fast 800 is here to help you maintain a life-long healthy lifestyle.
The Fast 800 is the umbrella term for a healthy lifestyle based on scientific evidence, encompassing diet, movement and mindfulness.
Our programmes, products and resources are developed alongside Dr Michael Mosley and based on years of experience with fasting, the 5:2, high intensity interval training (HIIT) and the Mediterranean diet.
The goal of The Fast 800 and our online programme is to empower you with the tools and knowledge to live a healthy lifestyle long-term. As a result, there are three flexible dietary approaches that can be followed and are designed to suit your goals and circumstances; you can switch easily between each approach as your needs change.
A short-term rapid weight-loss phase used as a kick-start to improve metabolic health until a healthy weight is achieved, or for up to 12 weeks.
Regular intermittent fasting for an effective, gradual way to lose weight and keep it off long term.
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, Dr Michael Mosley and a team of professionals developed The Fast 800 online programme, shakes and multivitamins, to help people lose weight, stay healthy and live longer.
Our actionable plan is based on the latest healthy living and weight loss studies, conducted by the most reputable institutions.
Research shows fasting outperforms a ‘standard diet’ when it comes to rapid and sustainable weight loss.
Before trying The Fast 800, I had no structure to my meals. Thanks to The Fast 800, following The Very Fast 800 and then The New 5:2 on the online programme, I’ve lost 26kg and my mind is so much clearer.
