Through our inspiring Consultants, we provide meal replacements and products that help aspiring dieters lose weight and improve their health. Our meal replacements and products are specifically designed to ensure each dieter gets the correct amount of nutrients while reducing their calorie intake. Developed, tested and validated by expert nutritionists and researchers - “Your body gets all the nutrients it needs and uses its fat stores for energy.

Great selection, spoilt for choice.
Great selection, prompt service love the variety of texture. We both enjoy our food and the diet is like a great tasting Vitamin tablet.

Really supportive consultant. Great flavours. Much quicker weight loss than mounjaro!
I’ve lost 7 stone in 14 months!
I’ve lost 7 stone in 14 months!
The 1:1 Diet has really changed my life, I suffer with chronic illness and mobility issues so needed to focus on my eating habits rather than hit the gym. I received lots of support, encouragement and I’m much more comfortable in my skin now!
Having tried slimming clubs with…
Having tried slimming clubs with limited success, I found The Cambridge Diet (now called The 1:1 Diet) 18 years ago, and successfully lost almost 4 stones. I now use the products on and off for maintenance. I have tried shakes and bars from various competitors, but they rarely compare well and the so-called support is cursory or non-existent. With The 1:1 Diet, I can count on their years of experience in this field, product quality and the fact that they are still around after 40 years offering one to one support to their clients. Not many of the competitors can say that.
The only diet that’s ever worked for me!
After struggling with my weight since childhood, I lost 5 stone in 5 months on this diet for my wedding and have kept it off thanks to the brilliant steps plan and my amazing consultant!
The 1:1 Diet is amazing
The 1:1 Diet is amazing. I have never been able to stick to a Diet the way I have with The 1:1. Being able to have a dedicated consultant to help me, weigh me & give me advice was vital for me to lose 3 stone in 2 months. The products are really tasty and they offer next day delivery and so much support.
Life Changing!
Life Changing!
A diet that worked for me and made me rediscover a good relationship with food! Consultants are so helpful and work to get the best for you!! Such a great variety of products and tastes took meal decisions right out my hands! Love it! 💜
The products are tasty and you get results!
The products are tasty, the support from your consultant is amazing and the results speak for themselves. It’s a flexible plan that you can introduce food when ready; it’s not just shakes either! There are over 40 products including cereal, soup, chocolate bars and more!

One to one diet is best product that ever existed. Works 100%,i adore it. For some one who is thinking
to start this program DO IT you will never regret!!!
This Diet is useless and didn't work…
This Diet is useless and didn't work for me plus its a total rip off because I paid delivery costs to consultant when i didnt need to. I discovered later when reading the T&C's that delivery is already included in price. Conveniently this wasnt communicated to me by consultant. Make sure you read the small print as they find every way of extorting money from vulnerable customers desperste to lose weight. Wouldn't recommend to anyone unless they have money to burn

I lost 2 stone in 2 months. It's hard going, but if you are strict and committed to the rules. The weight falls off. You have to be strict!
Charlie @Ipswich was absolutely amazing.
She helped and supported me through out the process. I'd definitely recommend her.

Great weight loss plan
Great weight loss plan. I felt fantastic all the time I was following 1:1 Diet. Loads of energy because only 3 products per day provide all nutritional RDA’s. No need for supplements. Full hydration and no need to obsess about food. I lost 3 stones in 3 months and I’ve pretty much maintained that. Definitely easy plan to stick to.

The best diet in the world
The best diet in the world!
Awesome products, support and a diet that actually does work without the need for surgery or injections.
Once the first few days are done and dusted, you’ll feel like a new person. I found I was no longer hungry, I was sleeping better, I had more energy and mental clarity. The trick is keeping yourself busy, drinking your water and focussing on small achievable goals. Your house will never be so clean and tidy!
I lost 4 1/2 stones in just under 5 months and it completely changed my life.
Huge range of products, not everyone will like every product but 99% of them are just lovely. If you’re super fussy there will always be something that you’ll like.
I saved a fortune when on plan too as I wasn’t buying all the junk/takeaways etc and the savings from that more than covered the cost of my diet every week.

The best diet I have ever been on
The best diet I have ever tried! Science based, clinically tested, safe and provides amazing weight loss results. There are 6 calorie programs, all tailored to you. Maintenance place a big role as it teaches you portion sizes and all about nutritious meals without fuss.
Personal support from your coach is included.
Cost wise - each meal replacement from The 1:1 Diet is cheaper than a cup of coffee from your local coffee shop. Highly recommend.

The best weight loss programme I have ever tried, easy and quick and the results speak for themselves. When I first did the plan I lost 12lb in 12 days I was over the moon I now use the products for maintenance after losing my weight. I love the range of products too and they taste great.

Absolutely life changing!
I lost 3 stone in just 10 weeks and have been maintaining my weight loss since 2013. This plan works when done correctly with the right support and guidance, it truly changed my life! If you’re looking for a structured, effective way to lose weight and keep it off, I can’t recommend it enough.

Best diet in the world.
I think the best thing about this diet is the fact I didn’t have to queue up with a bunch of strangers in a group which I hate. I had an incredible Consultant who cheered me on whenever I needed it, and went on to lose 7 stone in 7 months. I can’t thank 1:1 or recommend it enough. If you’re thinking of doing it - just start!
