The Fast 800 Reviews 859

My boss recommended Fast800 after I couldn’t get any real help from my GP (all I was offered was weight management group sessions, which honestly wasn’t suitable at all). I’d been putting in the effort at the gym but the weight just wouldn’t shift, and I was starting to feel defeated.

Then I tried Fast800, starting on the 26/05/2025. In just 3 months I dropped 32lbs, starting at 202.8lbs — and I’m still losing weight steadily, while eating real, satisfying food. The portions are surprisingly generous, nothing like the tiny plates you might expect from a “diet.”

I can’t recommend Fast800 highly enough — it’s completely changed my path and finally made weight loss feel achievable and sustainable.

The guidance works and is evidence based, not gimmicky. I like the choice of menu plans, meal suggestions and alternatives. The food planning is easy. I particularly like the daily exercises (which are graded to fitness level). The app is easy to use and packed with useful information (meals, exercises, meditations, general diet info). The program makes me feel in control of my eating habits and offers regular tips to stay on track. I have followed this for 3 years so far and my weight loss has been maintained.

The Fast800 is an easy and reliable app… reliable meaning it always opens efficiently and quickly all recipes are exceptional and I love that I can interchange recipes and flick to my favourites with no hassle. I used the app initially when I had a diagnosis of fatty liver, high markers for insulin and general fatigue. I used the very fast 800 - 8 wk program and after a revisit to Dr all markers were back to normal. Energy was improved. It works and I recommend to all my friends and family for assured results ❤️

Having been "dieting" for most of my life this is the first time I have felt in control. I have now lost over 20kg. I now have less than 10kg to go. It has taken time and I have gone up and down but thanks to the program I have the tools to stay with the process. I haven't once got to the stage of "what's the point" even after I have put on a couple of kgs.

I have been doing the fast 800 on and off for quite a few years now. The only criticism I have is the menus tend to stay the same. I like to use the fast800 to lose any extra weight I put on, but I am getting bored eating the same things. You post a lot of new recipes but don't incorporate them in the plan.

Started the Fast 800 to lose weight but also to change my eating habits for a better life style.
The additional information besides just nutrition is great. I use the exercise programs are excellent, the weekly reviews, tracking program all work and make following really easy. This is a very simple, informative program that actually works.

The programme is quite comprehensive and has guidelines for diet, physical and mental health aspects.

I have been using the fast 800 for several years and would not be without it. Great for losing weight if that's your goal, but also just as great for focusing on a healthy lifestyle.
I use the meal prep tool every week for my shopping, it gives me a full shopping list and also helps me to budget well and not overspend on unnecessary items at the supermarket.
I also love the exercise tool as there are so may workouts to choose from - to do at home or in the gym. It helps keep my gym routine new and interesting.

This online program is a well-researched program with tasty, balanced meals, daily workouts, and simple tracking. It makes staying healthy enjoyable and achievable.

The Fast 800 is the easiest and most effective diet I have ever done. The app works well and the articles are really helpful. I have learnt a lot. I have felt reassured that it is well researched and based on current knowledge with no aspect of fad or trendy. The flexibility has been particularly good for me with the ability to swap around meals. Possibly this has led to less than optimal weight loss but I can accept this trade off against the ease of sticking with it accompanied by very few feelings of hunger or deprivation.

A new way to eat, rather than a diet.
The 12 week 800 programme isn’t easy but it’s so rewarding. I strictly followed the diet, keeping to 800 calories and used time restricted eating as well. It worked for me! My goal was 30lbs, I lost 32lbs and feel great. It is a journey - buckle up and enjoy the ride!

Fantastic programme. I have struggled with my weight all my adult life. This "way of life" guidance was what I needed. It is sustainable and teaches the science behind the food groups we're eating. The exercise programme has ensured that I have now incorporated this aspect as a new habit into my life as well.
Having tried so many diets during my life, this is the only one for me.

I really love this program. I find it very carefully thought out and everytime I slip up its a real help in motivating me to keep going and achieve my goals. It is a good mix of nutrition, activity, mindfulness and emotional support.

Having tried so many diets and clubs related to ‘slimming’ which ended with the yo-yo effect, I read around the Mediterranean diet and then was inspired by Dr Michael Moseley’s work shared through TV and radio to try Fast 800. It’s been brilliant. The initial cost for 12 weeks was more economical than slimming club fees and I now pay maintenance fee monthly which once again is so much cheaper than club and/or gym membership!
And that’s the point. The Fast 800 is a comprehensive programme for a healthy lifestyle with recipes, meal plans, exercise plans and mindful knowledge about looking after both physical and mental well being. It’s been really successful for me and I use it every day both for meal plans and strength training exercises - I’m 68. You can start at beginner level and increase your difficulty over time - so many options! Similarly with meal plans - so many options of really tasty food so you can choose what’s best for you.
I really can’t recommend Fast 800 highly enough - it’s changed my life for the better completely. Blood pressure and BMI reduced to normal/good and I’m far more agile and mobile with no creaking joints or difficulty with moving or lifting things. I feel better now than I did 10 or 20 years ago!

I found it very helpful to have a wide range of recipes to help with my weekly planning and shopping. It made it easy to lose weight and feel well the community aspect is also very useful and helpful

I have absolutely loved following the Fast 800 plan! I’m a middle aged woman, who has slowly piled on the pounds since my 40’s. I’ve attempted to lose weight by being ‘sensible’ and /or starving myself, but nothing has worked. With the Fast 800, the detailed meal plans ( including weekly shopping lists!) has been absolutely fantastic. In 4 months I’ve lost 10kg and can get back into my clothes I’d been considering taking to the charity shop, as I didn’t think I’d ever get into them again. I look better, I sleep better and I feel better. The exercise plan I’ve been less assiduous with, but even that element is easy to follow and I try to do at least a few sessions a week.
If you love food, don’t want to go hungry and need to lose weight, I can’t recommend this programme highly enough.

Even though you think I have completed the 12 weeks,
I haven't I had to put a temporary hold on it following a serious concussion injury, I sustained at the end of
June from colliding with a jutting-out shelf corner in my bathroom. I was nearly 5 weeks into the diet.
It has been excellent though a bit challenging preparing the food. I am now near the end of the 7th week

As I didn't have a huge amount to loose, I was on the 5:2 and it worked brilliantly. The app and website are both easy to follow. The recipes are quick and easy and suited me.

I must have tried every diet under the sun but the Fast 800 has actually worked for me! I won't say it's the easiest to do as you cook everything from scratch but I think that's why I've succeeded. I started at the very end of April and completed the 12 week plan 3 weeks ago. I'm now in transition to continue my weight loss and healthy lifestyle journey. In that time I've lost 13 kilos with another 10 kilos to go. I am confident for the first time in years that I will achieve my goal.
I like that your menu plan is done for the week and that then generates a shopping list for you. You can swap out recipes that you don't like so it is flexible too. There are easy to do exercise plans and support through the community if you need it.
I can thoroughly recommend the whole plan.

I love the Fast 800 plan. I have been almost a lifetime dieter but I have found the Fast 800 to be most suited to my needs and lifestyle. The cost is so reasonable, just £3 a week and I feel you get such value for money with everything provided on the plan. I love the daily exercises which I can tailor to my physical capabilities. The coaches are very supportive and motivational and I even look forward to getting out of bed to start the day with them.
The diet plan and recipes based on the Mediterranean diet are amazing and I no longer struggle to think of what to cook. I am just working my way through the suggestions made. The plan even provides a comprehensive shopping list for the week's recipes.
The coaches provide weekly articles and information relating to the plan and a journal is also available for tracking progress.
I have found it very useful and encouraging to track my weight, BMI and body measurements and this inspires me to keep going!
I also love the Community Chats and support from other members and I would definitely encourage anyone to join this plan.
