What is the Intermittent Fasting Diet?

The intermittent fasting diet is a flexible eating approach where individuals alternate between periods of eating and fasting. Science has shown that intermittent fasting is effective for weight loss, as well as a number of other health benefits.

Embracing Intermittent Fasting UK

At The Fast 800, we’re all about introducing you to the science and benefits of intermittent fasting in the UK. This is a sustainable approach to eating, designed to fit within your day-to-day life to improve your health.

Intermittent fasting is backed by plenty of research and success stories, and has been shown to support weight loss and enhance overall wellness. The Fast 800 will guide you through the intermittent fasting approach best suited to your goals and circumstances. For our community of members, it’s much more than a weight loss tool; it provides structure for long-term health improvement and maintenance.

The Game-Changing Effects of an Intermittent Fasting programme

Ask anyone following an intermittent fasting diet, and they’ll tell you it’s a complete game-changer. Aside from the weight-shedding benefits, the intermittent fasting lifestyle can impact your life in many unexpected, positive ways. It can help you gain control over your hunger cues, improve your relationship with food, and lead to a deeper understanding of your body’s needs. It’s not just about the numbers on the scale; it’s about enhancing your overall wellbeing and vitality.

An intermittent fasting programme is the perfect gateway to a more balanced you. But it’s important to remember that everyone’s journey is personal and unique. That’s why our comprehensive fasting programme tailors the intermittent fasting diet to suit your specific goals, lifestyle and needs. This ensures that your journey toward better health and weight loss is not just effective, but also sustainable.

How we help

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 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.

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, 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.
