Only diet I have stuck to
After failing at every other diet I have finally found a diet I can stick to. I love the convenience of the products and the fact I’m not hungry. I have currently lost 3 stone and a half in 14 weeks.
I couldn’t do it without the support of my fabulous consultant.
I have tried every diet under the sun…
I have tried every diet under the sun and failed adding on more weight. This was my last resort before getting a gastric band. Thanks god I found this plan. I lost 7 stone in 7 months in 2015 and have managed to maintain ever since. Best thing I have ever done and counted up how much I saved. It would have cost me £10,000 for the band. In total I spent £1300 on products but also saved a fortune not buying g takeaways, rubbish and gained a whole new life!!! Do it!
Best thing I ever did
Best thing I ever did . 11 years on and still maintaining 5 stone loss .
I joined the group over 2 months ago…
I joined the group over 2 months ago having been a serial dieter with decades of yo-yo weight gain and losses - more gain than loss! I absolutely love the products, have lost almost 2 stone and have found Nicki (my consultant from Northamptonshire) incredibly supportive- she’s is trained in many aspects of mindset and offers sessions in many areas to help with on- going losses and how to maintain my weight. I truly think with Nicki’s support I will reach my goal and for the first time in my adult life find a way to keep the weight off. A huge thank you to Nicki and one 2 one !

Been on the plan for 5 weeks and have lost a stone. Feel great, clothes fit better, more energy, Far more comfortable with my appearance. I have stuck to the plan and increased my steps, and have not found the process difficult.
I gained 8 stones in my pregnancy and…
I gained 8 stones in my pregnancy and lost all my confidence. Drs said i needed to lose the weight or i was at risk of a heart attack. I had tried all the diets around and knew I needed the extra support of a consultant to talk too. I found the most amazing couple to support me and lost it all in 7 months. Ive been maintaining my weight loss for 8 years and have never felt better. My story has been featured on GB news, Bella magazine and several newspapers which is mind blowing. If I can you can too xx

This is a brilliant diet it works you feel better and healthier and it gives you your life back
Nicki from Northamptonshire is my consultant and she is amazing provides so much support and includes critical mindset coaching too
This diet has changed my life
Life Changing Diet
This diet changed my life after I lost 7 stone in 7 months. There is a misconception that it’s dangerous and it’s only shakes and soups. There’s 6 steps to the diet and only one of those steps is total meal replacement. It’s a low carb, low sugar, high protein diet - and if you follow the steps properly it will help you change your lifestyle. Highly recommended!

Beware of Misselling!
Beware of Misselling!! Lies from Consultants
Found out that a consultant is selling her weight loss journey thanks to the 1:1 diet but turns out she went abroad to get a gastric bypass!!!
Don’t trust them, they could be full of lies to get you to buy their products! I wouldn’t be able to trust any of them now as how would you know it’s the truth??? Very skeptical of the whole business now.
This Is The Only Successful Diet Plan I Can Do…
This is the only diet plan I can do.....seriously it is....and it's the very best as far as I'm concerned.
but please please PLEASE bring back the Cottage Pie meal??
And I really don't know why you took the Lemon & Lime Flavouring off sale, I used to mix that with the Pineapple, and it was so refreshing.....now that too has gone.
Will you ever be able to sell these again, or at least have something like them?
Thank you.
The best thing I have ever done for…
The best thing I have ever done for myself. It’s not easy but sooo worth it I’m currently on step 1B 9 weeks in and nearly 3 stone lost and can’t wait to move through the steps into maintenance. Feel amazing I have few health problems and for the first time ever I have a normal blood pressure.
I had a great experience on this Diet…
I had a great experience on this Diet plan 2014 & ae top motivated consultant in Scotland. And he did not charge me 70 pounds a week!. Or his other clients! He had his own weekly prices!
But that was him! I only knew him via a relative years ago. He should run Cambridge diet plan unless he's not already one of the bosses!.plus he'd give ge freebies new products or if your first starting out on the diet!.
No reply
Would be nice if Consultants replied. Contacted 3, silver, gold and diamond consultants. Not one reply. Very disappointing.
Amazing diet.
Amazing diet. Ive lost 4 stone.
Much cheaper than my shopping too. Mine is £53 for all my diet food.
One Chinese was costing me £10. A Bottle of coke £2. Add everything up you buy now before saying its expensive, it really isn't.
You get private support whilst losing weight. I saw my consultant at her home and she weighed and measured for free.
All the people saying you put the weight back on..... of course you will if you go back to eating crap and old habits! It doesnt magically appear again.
Obviously you will need to reduce your calories for life to maintain a new weight. You don't gain weight back eating a healthy diet, you put it on eating donuts, McDonald's and rubbish again.
Flavours are lovely, although there was a couple I didn't like. The consultant should swap if you do it within 14 days.
I've tried other companies and they don't match this diet. I've binned them so wasted my money there . Exante are disgusting too with no help or support.
My tip is look on their website and chose a consultant you like the look of, ring them and see where they are located and tell them what you need.
Literally this is the easiest way to…
Literally this is the easiest way to lose weight ever! I am menopausal and 11 months hysterectomy post op. I also have an Underactive Thyroid. For the last eight years I’ve been trying to lose weight, and in the last three years since starting the menopause I have piled weight on and no matter what I’ve tried…even starvation…I have not been able to lose any weight. It’s literally been impossible!!! I have been on the one-to-one diet for two weeks and I’ve already lost over half a stone!!!
I’m thoroughly enjoying the products. If you have a sweet tooth like me it’s a fantastic diet because there’s so many chocolate treaty bits!
The first week was hard, I got a really bad headache and I was very hungry, but the second week has been a breeze and I’ve felt fantastic! Probably is a bit Expensive but I think that’s part of what makes you stick to it, you don’t want to waste your money, And to be fair as I live alone I usually buy from my local shop so I’m spending almost the same amount anyway! Virtually no washing up, even my rubbish bin isn’t getting that full up just empty paper sachets lol! I literally cannot fault this diet, IT WORKS!!! I love not having to think about how many calories I’m eating and what I’m going to cook for dinner every night, I feel like I’d like to stay on this for the rest of my life! Haha! I love having a consultant to keep me on my toes and cheer me on. My lovely consultant also happens to be my niece who lost FIVE STONE on the one-to-one plan, so don’t believe any of the reviews on here that say it doesn’t work, because quite clearly, it does!!!!
There are thousands of consultants out there (there’s a fantastic community on Instagram) so if you have one you don’t like just get another.
If you are totally fed up with being a fat blob and you just want to lose your weight quick, this is the diet to choose!
Kimberley Maddox - Avoid
Kimberley Maddox: I unfortunately had a terrible experience with 1:1 Diet, my consultant was a money grabber and I have reported her to the company. She told me I could only order once a month and only boxes of 1 product at a time, not 1 or 2 products to try them, needless to say it cost me a fortune and if I didnt like the product she didnt tell me I could return them, I have now found out that you can return them within 14 days. I have boxes and boxes of the stuff under my stairs unused. So if you are in the Oxfordshire area do not use Kimberley Maddox.
Keeley from the word go was friendly
Keeley from the word go was friendly, funny and made me feel at ease. She helped and encouraged every step of the way. With her daily Insta Reels she made everything easy. Thanks Keeley for being you xx
The only diet to ever work for me
The only diet to ever work for me, especially having the support from my own diet consultant.
I had 3 meal replacements and a small healthy meal and still lost 3 and a half stone in 14 weeks. I couldn’t believe it.
