AS SEEN ON CHANNEL 4'S 'LOSE A STONE IN 21 DAYS', A NEW PROGRAMME FOR ACCELERATED WEIGHT LOSS COMBINING KETO WITH THE HUGELY POPULAR FAST 800
"A brilliantly informative book on how to optimise a keto diet." Daily Mail
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 both more effective than a conventional keto regime, and healthier and more sustainable. The secret to this 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, 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 tools you need to shift stubborn fat and transform your health for good.

The calories are low so you can eat a little more carbs (still low just not the very very low I used to do). The keto sticks will reassure you it works.
Bottom line is I found the traditional keto hard to do long term and this is better for my lifestyle. Its 12 weeks of low carb low calorie to lose up to 4.6lb a week (800kcal). Followed by slight relaxing of the rules which I personally appreciate. Its still low carb but means unlike the keto of old I used to do i won't be vegetable and fruit deprived. I just don't feel that lifestyle is good long term (and neither does Michael). It was great to drop weight but not to live on and this book follows that idea. You'll end up on a Mediterranean style diet at goal and that's been proven to be excellent for health.
The bad reviews from strict keto fans are unfair. This is an alternative that still allows the body to enter ketosis and drop weight fast.
Also the recipes are great - and many are less than 10g carbs. Pictured is Tandoori chicken kebab.
(I for one enjoyed the Black bean chilli with 16g of carbs as one of my two meals that day and I stayed in ketosis (see attached pic of my Ketostix). Win. 😊)
Another update - I've just done my first full week. I have lost a whopping 11lb. After the initial big loss I'm losing 1lb a day. My husband has lost a little bit more. We are thrilled and excited to continue. 😊

The recipes are pretty good, no complaints from me there.
The first half of the book for me what a lot of repetition of the previous books. The amount of new content does not justify a new book. All you need to know is keep your carbs under 50g a day whilst following the Mediterranean style recipes of the previous books.
Couldn't help but feel I was reading a lot of padding. The author loves testimonies about how the diet works for them. I would prefer details on the science, analysis of the latest research, making the case for the diet. If your new to this then the book is worth it. If you've got the fast 800, just drop your carbs to 50g a day and use the same recipes and wait for a second hand copy.
Wish I’d known as I’d have downloaded the kindle version instead.
That said I do rate Michael Mosley and so I’m sure I’ll gain something from it.
I know keto carbs should be below 20g per day, and this book has upto 50g of carbs per day, so you would not be in ketosis.
I was upset to see that the chilli recipe has a full can of beans added to the recipe, the chilli can easily be made without any beans.
