About this app

The Fast 800 is a personalised trainer and nutritionist, ready when you are, to support long-term weight loss and better health.

Developed by Dr Michael Mosley and independently validated by healthcare advisors, nearly 100,000 members have found success with our easy-to-stick-to programme.

With its personalised plans using science-based methods, The Fast 800 has helped thousands achieve their goals with intermittent fasting and the highly acclaimed Mediterranean-style diet. Our Programme is the easiest, most convenient way to learn how to improve your health, with the tools to help you do it and real, delicious recipes to ensure you enjoy it.

The Fast 800 is all you need to keep yourself accountable and start improving your health in a sustainable, delicious way. Via the app, you have access to:

- 18 healthy, nutritionally balanced meal plans

- A library of 700+ delicious recipes
- Daily guided workouts
- Low-impact to advanced exercise
- Resistance and HIIT training guides
- Pilates, yoga and stretching library
- Mindfulness guides and audio meditations
- Health Coach and Community support

While many people join The Fast 800 to lose weight, and lose more than 6kg in 12 weeks on average, the goal of the programme is actually to improve your health. As it so happens, weight loss is a consequence of that.

Over the years, members have seen significant improvements to their health, from reversing type 2 diabetes, to improving blood pressure and reducing the amount of medication they take.

At 54 years old, Helen, lost an astounding 21kg with The Fast 800 Programme. Helen was previously dealing with thyroid issues, fatigue and pain in her knees and hips. Since joining the programme, she's left that life behind and now lives pain-free.

“Over 13 weeks, I lost 21kg, which was a huge emotional journey. I've successfully reached the weight I was 25 years ago. Before I started The Fast 800 Programme, I was overweight and lethargic. I had issues with my thyroid and pain in my hips and knees (so much so, it was painful to walk). I had no self-discipline when it came to eating and I knew it was time to do something about my health.”

Finding better health shouldn't leave you feeling tired and hungry. Start your personalised programme and finally find what works for you.

Great content, bit laggy in some areas. Particularly connecting to the co.mu ity section. Improvements could be made for user experience in terms of being able to access original planned recipes without resetting all choices. Also in terms of the ability to set default numbers of people eating for different meals. E.g. lunch for 2, but dinner for 4 when everyone is home. Also in the groups section, my cohort isn't the defat view. You have to click into my groups first. Overall good experience

Hi Elixir, thank you for your rating and review :) We are sorry to hear that you have found some aspects of the Programme a little more difficult to use, and have made note of your suggestions and feedback for our development team. Kindly, The Fast 800 Team :)

Overall I'm very happy with the app. I particularly like being able to print out the weeks shopping list. I also like the option to swap meal suggestions although sometimes there is only 1 alternative. It would be good if you could add certain foods that are a no no, so that meals that contain them, don't come up. I have difficulty with beans and pulses. Quite often, the app will get stuck and I have to restart my phone, which is brand new so I don't think it's the phone that's at fault.

Great for type 2 diabetes I was diagnosed 2 years ago. So I signed up for the fast800. 3 months later my bloods are back to pre diabetic levels. Love the diet and this app makes it easy with your weeks shopping list planned for you. I do the vegetarian plan and the meals are delicious and easy to cook. It has to be a lifetime choice for me as diabetes is never cured. I have also lost 27 kg and am feeling fantastic loads more energy. Still have the odd bacon butty will never give that up!!!
