My consultant was fantastic
My consultant was fantastic - gave me 110% support, guidance and advice. Love the bars - easy to track and taste great 👍👍. I still have them now as they help me to maintain my weight
Such an easy to follow diet
Such an easy to follow diet, you can just eat and go which makes it so easy. It works lost a stone in my 1st month 2 stone over 3 months now maintaining.
It’s not just about the products
It’s not just about the products. The support & relationship with the consultant you have is what sets 1:1 apart
1:1 plan is my weight loss solution.
I’m on 1:1 plan again. Doing amazing. I first used this ten years ago. Lost six stone in five months. The difference and the key to my success is the 1:1 support. 24/7. Your own consultant to support. Motivate. Advise. I couldn’t have done it without her. She was my rock. It’s not an easy diet. There are different steps. Some meal replacement only. Some with food. You choose your plan with the help of your consultant. You move up the steps to make sure you maintain your weight loss. Too many times we lose weight and put it all back on again. I’d tried every club, every plan there was. I kept the weight off for more than five years then I lost someone close four years ago. Sadly I put a lot of the weight back on, 4 Stone. Not as much to lose as before. I am back on plan and I’ve lost 32 pounds in six weeks. My friend is at a well known diet club. She’s lost 10 lbs in ten weeks. She had lost a stone but she’s already struggling. Im not. I’m not hungry. I’m full of energy. My skin glowing. Choose a consultant that you like. That you trust. Definitely recommend this plan.
Best diet plan - it works
The only diet that ever worked for me. I tried everything without success until i was introduced to this diet.
Once you get your head in the right place the weight falls off really quickly which is really motivating.
Its easy to follow and the benefits are amazing and its not just about vanity. My confidence has increased I look really well and can wear great clothes, its other unanticipated health benefits such lower blood pressure, no more snoring, breathing better, more energy. I definitely recommend
Quick start and a steady loss! 2 stone down.
I started on the 1st January 2025 and had lost over a stone six weeks in, love the shakes, yoghurt pancakes are one of my favourite along with the porridge. Fits into a busy life, so instead of picking something up that's loaded with calories and sugar I now take a chocolate hey bar or lemon yoghurt bar with me. Still losing the lbs now have lost two stone!
I had an accountability partner—my…
I had an accountability partner—my consultant in Nigeria—and later, Yvonne Clarke in the UK, who encouraged me to become a consultant myself. As a consultant, I have occasionally needed to use the program for maintenance.
The progress I saw each week when I initially started motivated me to keep going. I enjoyed the products and appreciated the flexibility of moving up the steps whenever I felt the need for variety.
I loved that there was a wide range of products to cater to different tastes and cultural preferences.
As a woman of color, taste is very important to me. While I found some of the soups a bit bland, adding a touch of pepper made them even more enjoyable for me!
Great Experience
Great Experience, I initially started the Cambridge weight plan back in 2006, and lost 3 stone, which I have maintained, after having fantastic support from my consultant.
The 1:1 diet plan was perfect for me
The 1:1 diet plan was perfect for me. I had a personalised 1:1 consultant, no groups, no clapping just full support during my journey from my home. My consultant was very knowledgeable and great ideas to keep you focused.
You also can join in on the WhatsApp group for support plus you have the 1:1 app which you can track and get great recipes from.
Products were easy to order and a good variety.
Not all meal replacement
Desperate to lose weight, and knowing my mind set (removal of foods makes me binge), my consultant recommended step 3 to me, which is a mix of 1:1 diet products and calorie controlled foods! This step was the perfect balance for me and I have had many lovely hearty meals and treats whilst on plan and within my calories. Great support from my consultant whenever I need her and I’m heading towards my 3 stone weightloss in 6 months! And guess what….I haven’t had ONE shake! 😂
1:1 diet works!!
By time I found the 1:1 diet, I had already tried and failed on so many of the other mainstream diets, points, syns, herb shakes, you name it! But the 1:1 worked for me and stuck too, I lost 3.5 stone/ 23kg in under four months and I’ve kept it off!!
4 and a half stone lost in 6 months
4 and a half stone lost in 6 months.
And not a needle in sight.
I'm over the moon.
Loads of different products to choose from so I never felt I was missing out.
All of the chocolate bars are delicious.
Give it a go you won't be disappointed.
Cambridge 1:1 Diet, I lost a stone for Lent
Cambridge 1:1 Diet was the first diet I consistently lost weight. I had tried every other diet, but I found even when I stuck to them 100% I have weeks with no or very little loss. Which was so disheartening.
I wish I’d found this diet a long time…
I wish I’d found this diet a long time ago! Best diet I’ve ever done, lost 2 1/2 st in 10 weeks and have maintained a size 10 since! I would highly recommend this diet.
THE TRUTH ABOUT THE 1:1 DIET
The truth is the 1:1 diet transformed my life in ways that I’m still experiencing after 19 years since I did the plan…weight and health has been on point ever since and there is no turning back thanks to the amazing experience of being on the 1:1 diet..MY LIFE IS FOREVER CHANGD
THANK YOU
I’ll be honest—I was sceptical about…
I’ll be honest—I was sceptical about the 1:1 Diet at first. I’d seen a friend try it and thought, “There’s no way I could stick to that.” But after trying every other diet under the sun and still not getting anywhere, I decided to give it a go. I met with a consultant, got started… and the rest is history.
Fast forward, I’m now 12 stone lighter—and I’ve kept the weight off since 2019. This plan didn’t just help me lose weight—it completely changed my life. My only regret? Not starting sooner.
Absolutely love this weight loss plan
Absolutely love this weight loss plan, it has completely changed my life and because I followed the whole process start to finish including maintenance I have been able to maintain my weight. Ive lost 5 stone and maintained since 2019 and only go back on it now after an event like Christmas or a holiday to just blitz a few extra lbs off. It works brilliantly and the products are super tasty. It’s great that there are plans that contain conventional food too for people who don’t want to cut any food groups out, but there’s also more strict plans for those who find it helpful.
I’d ignored it a a quick fix Thank god I didn’t listen to that. …
I first lost weight with This amazing Duet 2 decades ago. The journey I had was huge and one I’d yo-yo with for as many years . It was my last call this or BARIATRIC surgery. I wasn’t willing to risk my life on that . 11 months later I’d transformed my body but also my mind. This ensured that now 2 decades on I knew how to maintain. THIS is the difference The 1:1 Diet has above any other Diet. The Control it provides the so very important FULLY TRAINED CONSULTANT . Many that have added skill sets. That’s the difference plus you get all this for the price of your TASTY SCIENCE BACKED, FULLY PROVEN NUTRITIONAL PACKED MEAL . The cost less than a large glass of WINE.
Yet this transforms your future .
My Diabetes went into remission after just 2 stone weight loss it’s never returned. I ate conventional FOOD alongside . The support is unbelievable nothing compares to this.
