Healthier Living Through Weight Loss

In collaboration with Dr. Michael Mosley, we apply cutting-edge scientific research to develop an innovative approach to weight loss and healthy living.

Healthier Living Through Weight Loss

The Fast 800 is a comprehensive approach to a healthy lifestyle, rooted in scientific evidence and focused on diet, movement, and mindfulness.

Developed in collaboration with Dr. Michael Mosley, our programs, products, and resources are backed by years of experience in fasting, the 5:2™ method, high-intensity interval training (HIIT), and the Mediterranean diet.

Our goal is to equip you with the tools and knowledge to maintain a healthy lifestyle for the long term. With The Fast 800™, you’ll have access to three flexible dietary approaches that can be adapted to your goals and lifestyle, allowing you to switch between them as your needs evolve.

The Very Fast 800

A short-term, intensive weight-loss phase designed to quickly improve metabolic health. This phase can be used to kick-start your journey until a healthy weight is reached, or for a maximum of 12 weeks.

The New 5:2

A consistent intermittent fasting approach that offers a gradual, effective method for losing weight and maintaining it over the long term.

Way of Life

A long-term maintenance strategy featuring Mediterranean-style recipes, perfect for managing weight and enhancing metabolic health.
