I signed up for the Fast800 12-week programme, paid the initial £29.99 and then decided to cancel within the 14-day cooling off period. Several weeks later, and I have sent 3 emails and one online query requesting a refund and confirmation that no further payments will be collected
but no response received and no telephone number given for customer support.

I love the new salted caramel flavour shake. It really makes losing weight easy!

Reply from The Fast 800
Into my 3rd week. Lost 3 lbs week 1, nothing week 2, hoping to do better week 3. We shall see.
The Fast 800 protein shakes are too expensive and gave me terrible diarrhoea, so have switched to another cheaper vegan brand that has pumpkin as the main protein source. The Fast 800 regular shakes use whey as the protein source, so might be the whey upsetting my digestive system. Not sure. Experimenting.
The fasting days (I’m not fasting every day - somewhere between the 2/5 , more like 3/4 which i find more manageable.) are very do-able and don’t make dieting seem like an up-hill chore. So you can find your own balance.
I am enjoying using Google Co-Pilot AI and an Excel spreadsheet to help me work out my calories every day and tweak recipes, but that’s just me, not a requirement of this diet. I’ve added this as a tip.
I enjoy cooking anyway, but the Med diet, which this diet is based on, has encouraged me to ditch the carbs and embrace a variety of vegetables and seek out healthier less calorific alternatives such as lentil pasta, which tastes the same but half the calories.
I have a freezer full of ready-type meals from my last supermarket shop, that now i’ve gone back and checked them, can see they have horrific calorie and low nutrition content, so i’m going to slowly use them up over a longer period of time on non fasting days to get rid of them. And then just not buy them again. And they are expensive anyway, so hope to save a few pennies there too.
On the whole I am hoping for good things from the Fast 800 Diet. It has certainly made me re-evaluate what i’m eating on a daily basis, but it’s still early days. I need to lose about 6 stone, which is frightening, but once you get in the habit of calorie counting by switching permanently to a med-based diet, I am hopeful and determined I can achieve this at a steady rate - i will come back in 6 months and update this review on my progress.
I do feel the Fast 800 Diet has given me the tools to lose weight and tackle a few other health issues, so in that respect it is very empowering.
The only reason I’ve scored it 3 stars and not 4 or 5 is down to the very expensive protein shakes that gave me diaorreah. I also feel they are overpriced, are too bitty although the flavour are nice, and now can’t drink them so have wasted my money buying 3 packs.
So for anyone starting out this diet, I would suggest using vegan based protein shakes instead, which usually have pumpkin, or pea as their protein base and avoid whey protein. But everyone is different. Or buy one packet and see if it works for you before buying more.
I also bought the fast 800 recipe book, which I have used multiple times now. Recipes are a bit basic, but i’ve tweaked them by adding herbs and more textures using chopped nuts or seeds. I also can’t eat peppers so have subbed them in certain recipes.
What I like most about this diet is that it’s more of a permanent eating regime change - which is fun to experiment with and using AI Copilot alongside it has been an incredibly useful support, because it offeideas and tweaks which can be custom made to your own specific health issues.
You do have to be prepared to buy lots of fresh vegetables and I use RiverFord organic weekly deliveries for that and they also can provide box recipes which tell you the calories, so I’ve found that very useful to incorporate into the Fast 800 diet.
I must admit fresh veg used to scare me a little, things you buy which stay in the bottom of the fridge until you throw them away again…..but not now. I’m finding I am buying more fresh veg, and actually eating them.
I have felt a little weak after a fasting day, but my fasting days are my swimming days - where i blob around the pool like a blue whale. I know that’s where I should be and not sitting in front of the TV, but i do feel like I need to rest more afterwards.
I am also AU-ADHD, which makes the Fast 800 diet easier in some ways because I frequently forget to eat in the day anyway, now I just have to remember to drink, which is easier. And then plan a meal for when my partner gets home. He is doing this diet with me and the only thing he doesn’t like is the lack of fruit in it as he was eating fruit every day for his lunch and nuts, but when you add up the calories in some fruits its as bad a eating sugar, but thankfully we were already eating a lot of blueberries and other berries which fits in perfectly with this diet. I do miss my daily banana it has to be said, but now they are treats not every day foods.
Also big up for kallo rice crackers and even their chocolate coated wafers are delicious and low calorie, so can be added in as treat without the guilt.
I would also say if you have a local farm shop near you - use it. Mine has a fish stall one day a week so it’s like ditching the mega shops at the supermarket and going back to how our parents / grandparents shopped before supermarkets made us all fat and unhealthy.

I have always been very happy with my purchases however this time I have found the peanut bar very disappointing.
Sorry!
It tastes stale and the chocolate coating has a white sheen to it.
It IS still in date…..

The Fast800 Programme is the only weight loss programme that has worked for me with long term results. I have challenges with an underactive thyroid and commercial weight loss programmes did not work for me once my thyroid function started to be a health challenge. My husband is also following Fast800 online and he is fitter and more energetic than before. We are both in our 70s so maintaining our health is a priority. Recently I underwent major surgery, and the Fast800 programme was greatly instrumental in a good recovery and restoring better health. The health coaches are always helpful, quick to respond, very knowlegeable. The articles are very interesting, and of course the recipes are delicious. We enjoy putting together our weekly meal plans and know that we are getting optimum nutritional support.

In January 2023 I saw Michael Mosley's TV programs and did the Fast 800 with the books for three weeks and lost 3kgs. I then found myself reverting back to my old habits!!
This inspired me to sign up with the Fast 800 program for 12 weeks. I lost 13 kgs in the 12 weeks (I lost 16kg in total). I realised very quickly that this program was going to work for me and I saw amazing results. The recipes are so tasty and easy. I went on the TMAD Fast 800 which I still do two years later - TRE works for me. Living on my own the shopping list being available for the menu is amazing. Virtually no waste of food. I only shop once a week. I'm sure I'm saving on the food bill. I do lots of 'swapping' when making up the weekly menu nowadays as I have my favourites.
I did all the goal setting exercises on the Fast 800 and still read all the Knowledge pieces provided each week.
I have now been doing the Way of Life TMAD for two years and have kept my weight within 2-3 kgs of my goal weight. I cannot speak highly enough of Michael Mosley and the Fast 800 team.
My initial aim with the Fast 800 was to lose weight and keep fit so I can stay living independently in my apartment for as long as possible. The Fast 800 has enabled me to do this.
There is so much more I could write.
Thank you everyone in the Fast 800 team. You are all amazing.

I’m currently doing the 12 week program, I’m not following it religiously due to also doing high intensity fitness, I’m using mainly for meal ideas, I’m loving the meals, the app is really easy to navigate, the shopping list is a massive help, would highly recommend this program!!

Ordering is simple and standard delivery is really speedy. Packaging is not excessive. I usually order when there are special offers and bulk buy to reduce postage costs. The shakes are expensive, but you get what you pay for in my view. They are a great way to start the day after fasting.

The Fast800 12-week program changed my life. After decades of yo-yoing with weight loss dieting, my weight continued to increase until I hit 115kg and a waistline of 124cm just before Christmas 2022. I saw a photo of myself in a tee shirt and observed prominent fat rolls around my waist; I felt disgusted with myself. In January 2023, I viewed a Michael Mosely series on tv about his weight loss program in the UK post-COVID pandemic. I was impressed and committed myself to the program in January 2023. After 12-weeks I had lost 22kg and by July (7 months later) I was at my goal weight of 90kg and waistline of 104cm. Truly an amazing outcome. Two and a half years later, my weight and waistline has slowly increased back to 105kg due to a range of factors (not related to the program). However, I am now just starting another Fast800 self-paced routine to bring my weight and waistline back down again. I am confident with the Fast800 program that I will return to my goal weight and waistline.

I really am loving undertaking this program. The app is easy to use and is customisable to my preference. It is an easy to follow program with a 'one stop shop'. Food, exercise and mind all catered for.

This is my last week on the 12 week programme. I decided to spread the calories over 2 meals, avoiding breakfast. This has worked really well for me. No hunger in the mornings.
I had a few headaches in the first week. This was resolved by drinking more.
The meals are yummy & if there is something you do not like you can swap.
I opted for the low impact daily exercise which is very manageable (time it takes to complete & effort). I have combined this with daily walks & cycle rides.
So far 14+kg weight loss. I feel so much healthier, can wear the clothes which had been abandoned to the loft & I am happier.
The program is a WIN for me.
Next Monday I will go onto the 5:2 diet. The programme gives you 1 month free of cost.

Absolutely delicious shakes, filling and very easy to prepare. Perfect for kick starting weight loss.

An excellent programme where menus, shopping lists, exercises, support, and reading matter are easy to access day by day, week by week. Takes a bit of getting used to but take the time to do the reading and watch the various videos. The idea is to change your thinking and develop good eating habits. It’s working for me

Lots of simple, quick recipes, easy to follow guidance, advice & ideas. Plenty of support from fellow members. Loads of exercise routines, for every ability to do in the privacy of your own home. Huge amounts of support from the Fast 800 team with suggestions & ideas to overcome common issues. You can dip in & out; nothing is mandatory, so use as much or as little of the programme as you wish.

The Fast 800 has changed my life. It is easy to obtain your goal of losing weight because the web site is easy to navigate. Staff are very knowledgeable and answer questions readily. It's extremely helpful to be able to ask any question at any time.
The whole program is a happy and friendly one. You feel as if you are receiving individual attention and actually you are.
The ability to plan your menu and shopping and to swap meals is invaluable. It makes the shopping, cooking, eating process run smoothly and easily.
Occasionally challenge weeks are held and these are a unique experience and very valuable.
Each day an exercise routine is available for you to follow or you can choose from the wide range of exercises available.
There are now 900 recipes to choose from and this program has taught me to eat things I didn't think I would like, but do!
I would most definitely recommend it to everyone.

I joined Fast 800 last October. I just wish I had found it sooner. The programme is easy to follow and includes additional help with mindfulness and exercise to suit everyone at every level. By CHristmas I was overweight rather than obese and I am now just one kilogram overweight - and I feel great! I've learned how to eat and exercise properly and I am continuing to follow the maintenance programme as the (gorgeous) recipes and linked shopping list make planning meals a doddle. Sign up!

Fantastic recipes and lots of variety. it’s great for planning meals which saves me so much time. Also lots of options on the type of program you want to follow

I have struggled with my weight all my life, tried lots of diets, which i have failed to maintain due to them being unrealistic. Fast 800 has been a completely different experience. There are so many delicious healthy recipes that are easy to follow and are full of flavour (I follow the vegetarian plan). My mindset and attitude to food has completely changed, I enjoy preparing and eating the recipes which leave me satisfied. The food noise and guilt have gone, and I have fully embraced my own fitness and wellbeing.
