From the multi-million-copy bestselling author Dr Michael Mosley comes the ground-breaking The Fast 800 Keto, a dynamic new weight-loss programme that combines a keto diet with low-calorie intermittent fasting.

A keto diet - where you flip your metabolic switch, going from burning sugar to burning fat for fuel - leads to significant weight loss and other potential health benefits. But one of the challenges of a standard low-carb, high-fat keto diet is that it can be hard to stick to.

Dr Michael Mosley's Fast 800 Keto is more effective than a conventional keto regime, and healthier and more sustainable. The secret to this accessible new approach is that it combines keto with intermittent fasting, which means you go into ketosis faster, while also being able to enjoy delicious Mediterranean-style food.

Based on the latest dietary science, this book presents a simple, practical, highly flexible three-step programme to ensure you lose weight rapidly and safely, while preserving your metabolic rate. It includes protein-rich, low-carb recipes and easy-to-follow menus from bestselling author Dr Clare Bailey, and all the other life-changing tools you need to shift stubborn fat and transform your health for good.
