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

Lose over 6kg in 21 days with this combined program for accelerated weight loss.

In The Fast 800 Keto, Dr Michael Mosley's dynamic new weight-loss program combines a ketogenic diet with low-calorie intermittent fasting, giving you the best of both worlds to achieve long-term success.

Dr Mosley presents the latest science on the ketogenic diet (when your body shifts from burning carbs to burning fat for fuel), explaining how keto works and why it is good for you. His ground-breaking new approach helps you get into ketosis faster so you can lose weight safely, improve mood and reduce blood pressure, inflammation and blood sugars. And the good news is that with The Fast 800 Keto, the carb and calorie levels are a little higher so the program is more sustainable.

Dr Mosley offers clear advice on which foods help put you into ketosis, which foods bring you out of it, how you can tell if you are producing ketones and how to ensure you are following the diet safely. With an easy-to-follow, step-by-step program that offers plenty of tips and advice to help you stay on track, the book details fascinating case studies, including some of the participants from Dr Mosley's new SBS TV series, along with fifty delicious, low-carb recipes and menu plans by Dr Clare Bailey.
