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:

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.

After making a new profile and paying for membership, the app is stuck in loading and preparing my plan. I cannot do anything in it, as it's just loading. I have emailed the support about it with no answer to date. Very disappointed that I can't use something I paid for. From previous experience the app was working great, and the whole program is amazing. So my rating is purely for the lack of technical support and being unable to use it at all. The money was taken for membership regularly.

My 5 star rating is about the program as much as the app. I'm 3 weeks in and feel so much better. The food plan is great, flexible and really suits me. Shopping list feature is super helpful especially as I do my shopping online so I just work my way down the list. I'm a menopausal 50something who has struggled with weight gain for a couple of years (longer probably) and this is the first program where I have made progress and feel like I can keep it going.

I was interested in joining online and downloaded the app. I had created an account a while ago but never completed the sign up to the programme. I signed in to the app and then received a message advising I would need to go to the Web version. I've tried but now given up. The app doesn't reflect what a brilliant idea the programme is.
