Feel supported to reach your Weight Loss Goal

Tasty and varied products. Not just soups and shakes. Amazing support provided by my consultant who is always a message away and provides friendly and tailored guidance. The ‘food noise’ has gone and I feel focused and healthier.

The wonderful support from my consultant. She taught me so much about how to lose weight healthily and keep it off long term. I lost 4.5 stone over 25 years ago and today my weight is still in the healthy range. I can't put the date that I started on plan so I am putting today's date

This plan changed my life

The Cambridge weight plan changed my life. I followed the abstinence step for 3 months and stepped up over the following month and lost 3&1/2 stone. It was good to have a break from food and reset my eating habits. I am maintaining now and have done since

A diet that really works!

I started the diet after having my 2nd son in 2017 and lost 2 and a half stone. I found the plan easy to stick to and loved the products. They are full of all the nutrients and minerals you need to diet safely. I felt great! I have been maintaining my weight ever since. This diet really does work!

The 1:1 Diet gave me my life back

The 1:1 Diet gave me the support I needed to lose the weight for good. I loved the tailored plans, the fact I could learn about portions and making better choices and I knew I was getting the right nutrition every day. I enjoyed the products too and the choice is wide and varied.

No more Yo Yo dieting for me.

After years of yo yo dieting I found a diet plan that yielded great results whilst teaching me the importance of changing my eating and drinking habits to maintain my weight. Don't get me wrong, I still like the things I like but it's occasionally rather than daily. Sometimes it can be tough, however, keeping in touch with my consultant after losing the weight has helped keep.me on an even keel.

Still as good 20 years later!

I used the products 20years ago to lose five stone and loved them then. I recently decided to go back on plan to lose some menopause weight and the products have got even better! So many flavours and choices and still the same fabulous support from consultants. Even better - it’s now delivered right to my doorstep and I can weigh myself at home and check in on the app!

Lost 2 stone in 2015

The consultant I had back in 2015 was amazing. I followed step 3 where I had a main meal with my family every day and lost about 2 stone.

I have managed to keep it off since 👍

No longer a sceptic

Having done similar diets before, and failed, I was sceptical. But the 1:1 sessions with my consultant was a real game changer. Plus, the products are fab!!! Really tasty and easy to prepare

Great support

I always had face to face weigh ins, as this worked for me - which I found professional and informative and always very friendly with no judgement.

Life changing!

The 1:1 Diet by Cambridge Weight Plan is amazing! It changed my life 15 years ago. I lost over 7 stones on the plan with the help and support of my personal consultant. No group meetings, just myself, my consultant and a selection of tasty meal replacements. It's the perfect reset button to cancel food noise and build a new relationship with food moving forward. I still enjoy using the products to this date to help maintain or if I want to trim a few lbs.

I loved the fact that my consultant visited me in my own home and it was a 1:1 meeting at no extra cost.
I live in a rural area and busy at work so it was very important for me that I had someone visit me

Losing Weight and getting healthier & fitter

The support and motivation for me was very important Knowing I was accountable to a 1:1 Diet Consultant kept me on Plan. As the weeks went by the routine helped me to be responsible and value the Plan as results were happening.
I felt so well on the Diet too as the vitamins and minerals helped me feel so well and I engaged with the water I learnt to consume and now I still stick to that.
I have been amazed how I now can eat nutritionally and have learnt portion control and kept away from unhealthy food.
Now I make sure I look after my health with daily exercise and healthy foods along with one product for maintenance to keep my intake at a level that maintains my weight.

Only diet that works for me

I had tried all usual diets and had always considered food replacement diets as faddy.
How wrong I was, only diet i stuck to, weight came off quickly, taught me to eat less. Main difference was seeing my Consultant every week to keep me accountable.The weight has stayed steady for the last 7 years.
Would highly recommend, not easy but worth it

The magic of chocolate shakes!

Although I tried a number of different flavours I found the chocolate shakes were my favourite so I lost three stone having three chocolate shakes a day!
With the friendly guidance and support of my consultant I followed the Steps, adding food back into my diet and having less shakes so I could maintain my weight loss forever 🙂
