Six years ago, Dr Michael Mosley started a health revolution with The 5.2 Fast Diet, telling the world about the incredible power of intermittent fasting.

In this book he brings together all the latest science (including a new approach: Time Restricted Eating) to create an easy-to-follow programme.

Recent studies have shown that 800 calories is the magic number when it comes to successful dieting – it’s an amount high enough to be manageable but low enough to speed weight loss and trigger a range of desirable metabolic changes.

Depending on your goals, you can choose how intensively you want to do the programme: how many 800-calorie days to include each week, and how to adjust these as you progress.

Along with delicious, low-carb recipes and menu plans by Dr Clare Bailey, The Fast 800 offers a flexible way to help you lose weight, improve mood and reduce blood pressure, inflammation and blood sugars.

Take your future health into your own hands.
