Weight Loss & More!
Being on plan not only helped me lose weight but also eased my symptoms of IBS. Thoroughly recommend the lactose free chocolate shakes!
Great diet. Just the best. Others aren’t close
I really thought that the diet was perfect for me as I could choose a variety of meals and bars and that you weren’t stuck with certain products. It was good that if you just wanted to have bars you could. Have shakes you could as long as the amount met your plan that you had to be on. The consultant knew her stuff and was amazing at offering advice.
The 6 step program is so easy to follow…
The 6 step program is so easy to follow and the meals, bars and milkshakes are delicious which makes it so easy to maintain. This coupled with the support of my consultant helped me to achieve my 20kg weight loss in 4 months, and still maintaining 2 years on. I highly recommend this weight loss plan.
Great products and excellent support
I lost 3 stone and found the products really tasty. There was so much choice not just shakes like other diet plans.
My consultant was amazing and became my good friend which was a great bonus. I could not have continued without her help.
Great Consultant, great diet
My consultant is lovely and really supports me and keeps me accountable. The products are varied so you should be able to find something you like and they are very tasty. New products are launched regularly. People are sometimes put off by the price but look at it as an investment in yourself and your future, you are worth it.
The only Diet that has worked for me
The 1:1 consultant and their knowledge around the steps.
The support is phenomenal!
Finally a Diet that works!

I started my journey with Cambridge …
I started my journey with Cambridge weight plan back in 2012 after 5 months of been on plan I lost 5 1/2 stone and I felt better then ever . Some days it was hard but when you see the numbers on the scale going down beat feeling in the world x
Then in 2014 I became a consultant and started helping others to achieve their goals and dreams and I’m happy to say still helping people to achieve their goals and still loving it
This diet has changed my life
This diet has changed my life! I lost 3 stone in 3 months and the support I received from my consultant Sally was truly what made the difference, losing weight was never going to be easy, but my consultant was motivating, fun and there for me both through the highs and the lows - don't delay reach out and find your consultant and lose the weight!
The 1:1 Diet worked for me
The 1:1 Diet worked for me, where no other diet did! The meals all taste great and there is a wide range to choose from. For me, having 1:1 support is so much better than a group setting. I now use some of the meals to maintain. Happy days!
The 1:1 Diet is a game changer
The 1:1 Diet by Cambridge is a game changer, I lost 2 & 1/2 Stone on this diet and lifestyle plan, helped me to eat cleaner and take my diet seriously.

I thought I was a lost cause till I found this plan! I suffer with auto immune issues, hpothyroidism and menopause symptoms. This plan gave me the freedom to see a future, it stopped the noise and worked quickly which helped with my motivation. I would recommend anyone to try, and the additional benefits of all those vitamins gives you a rea boost in energy.
My experience was great
My experience was great. My consultant was amazing and I did love the products and the process was easy to follow
Excellent Support and Effective Products
I joined the plan with the help of a friend who is a consultant. She provided excellent support and had extensive product knowledge. The products were not only nice but also made me feel full and healthy. It has been easy to sustain a healthy weight ever since. Highly recommend!
No regrets whatsoever
The variety of food products available on the 1:1 made staying on the plan really easy. My consultant had been successful on the program herself so she knew the struggles I was facing and offered me empathetic support and encouragement when times got tough. I think this made the biggest difference between this program and group sessions elsewhere, which were not for me. I worked through the steps program and learned how to eat for my post menopausal body. I’ve been maintaining my weight loss for 2 years now, in fact always a few pounds under to allow me to enjoy weekends and events without piling the weight back on. I’ve really cracked it this time, thanks to the 1:1 Diet and I’m forever thankful I made the decision to start.
It worked for me!
I had tried many diets over the years, but had always been unwilling to try meal replacement plans.
But I liked the idea of one to one consultation and weekly follow ups plus a definite plan to keep me on track. So I gave it a go and it was great, I lost 7lbs the first week and eventually a stone in the first month! The products are nice, there’s a big range so I found the ones I liked and then it was easy, they will swap products for you if you tell them within two weeks. I liked the porridge, soups, Thai noodles and lots of the bars. I’d put on a bit of winter weight so had another go recently and lost 6lb in a week, I’m still on my reset!
3 Stone off on my terms.
I returned from living in the USA for 19yrs 3 stone heavier and felt the old ways of attending a weight loss group didn't appeal to me.
I wanted results..a friend recommended The 1:1 Diet to me and I found myself searching online for a consultant until I found one that I felt I could connect with.
I lost 3 stone in 4 months and was surprised I never felt hungry at all.
I would thoroughly recommend this Plan as it is simple, effective with long lasting results.
I loved the fact I didn't have to leave my house every week to be 'weighed' by some stranger, or sit in a cold Church hall to wait my turn to be spoken with.
My consultant was friendly, flexible and supportive.
Go for it and lose the weight forever...
The recipes are great and easy to do
Lost 3 stone in 12 weeks, maintained for 5 years now
My consultant was amazing, I felt listened to as a person (something other weightloss plans don’t have!) I lost 3 stone in 12 weeks and have maintained for 5 years. The plans were easy and products are really nice with big variety.
