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
- Options for keto, vegetarian and 5:2
- 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 :)

Great for calorie and macro tracking and the shopping list function is very useful. It is a bit clunky to use when batch cooking and therefore not needing ingredients on the shopping list etc. The user interface is mostly fine once you get used to it, but it could do with modernising. The Advanced training sessions are way too easy if you're already well into your fitness, so I don't use that function at all and just write my own. I've not used the support channel or information sections.

I have done the fast 800 in the past with the books but the app makes it so much easier...all your meal plans, shopping lists, work outs and support with the "community" all there for you. Especially when you are working. You can swap meals and plans... it's all about what's best for you. It's kept me motivated and even after the 12 weeks we're up, I'm still using the app for maintenance and motivation. The workouts and mindfulness are brilliant too and it's all evidence based!
