Cambridge Diet

cambrigde-dietThe Cambridge Diet is based in the United Kingdom. It has it’s origins from the Cambridge University in the late 1970s.

The Cambridge Diet was officially launched in 1984, but now has distributors worldwide. Online it is known now as the Cambridge Weight Plan.

The Cambridge Diet Plan

The Cambridge Diet is a Very Low Calorie Diet (VLCD) and is made up of pre-packaged foods. The foods have been formulated to provide precise amounts of vitamins, nutrients and calories – and are available as sachets (shakes or soups), bars, or “brix”.

The daily calorie levels start as low as 415-500 calories per day. After a period of time (a maximum of 4 weeks), the calorie levels are upped (first to 790, then to 1,000 calories per day).

It is essential that copious amounts of water are drunk during the diet to avoid dehydration.

Dieters are given one-on-one support through independent Cambridge Weight Plan Consultants. These certified individuals will encourage and help you track your progress during weekly meetings.

Success Stories

On the Cambridge Weight Plan’s website there is a community forum for users to support each other and also many success stories of those who have used the plan successfully.

Here’s an excerpt from one customer’s experience:

Cambridge has completely transformed my life and gave me foundations to build my new lifestyle which has helped me maintain my weight for 13 years. I kick start my manic days with a Cambridge shake and am able to take on all kinds of challenges, as a Cambridge Consultant, MMA and Kickboxing teacher and a mum of two. I am a health and fitness ‘fanatic’ now. Don’t think of Cambridge as a temporary solution, if you focus, follow the steps up and are committed to change you can create a whole new life for yourself and keep your weight off for good. – Rehana K.


Although the Cambridge Diet is really low in calories, they recommend that dieters exercise, but according to their unique needs and medical profile.

The independent Cambridge Weight Plan Consultant will be able to help dieters choose which level of exercise is appropriate as well as offer exercise suggestions.

Cambridge Weight Plan Costs

The Cambridge Diet costs about £45 a week or about £2.15 per meal, but can vary according to your unique needs.

Your independent Cambridge Weight Plan Consultant determines the exact cost based on your needs.

A Risky Endeavor?

The Cambridge Diet should be used only under the guidance of a medical practitioner.

In the UK, the diet is only available through accredited counselors and to people with a BMI above 25.

Despite research confirming the benefits of VLCD’s they should only be used under medical supervision. Exercise cannot be maintained (except for very low intensity exercise) during the diet, and additional fiber may be required to prevent constipation.

Also, by using the Cambridge Diet’s meal replacement products, dieters may have trouble keeping the weight off once they resume a normal diet.

Be very careful with the Cambridge Diet.

Different Versions?

The Cambridge Diet is only available through distributors. The distributors in the USA provide slightly different formulations to those in the UK.

Also there are other versions of the Cambridge Diet that may not be legitimate.

    Hi guys. Its the first day of SS for me today and im finding it really hard! Sticking to it at work isnt too much of a problem but coming home to a family who are eating pasta, potatoes and garlic bread is soooo hard! How did everybodies first week go? I’d love to how much everybody lost in the first week or simply any tips to get through the first couple of days! Im determined to stick to it as ive got about 3 stone to lose!

    Hello everyone,

    I am sunil from UAE, 34 years old. I was 140 kilos when i started this diet on the 26th March, 2010 and till now i have lost about 35+ kilos and about 6-7 dress sizes, this thing really works. I have to lose another 15 kilos until i come to the maintainance stage. People who are thinking of doing it, please do go ahead and jump into it with closed eyes as i guess i am the best example. Had tried all different diets in the world but my weight would come back as soon i stopped those diets and this is the only diet where i dont feel hungry, have the energy to carry on and i am looking so good these days and most of my friends whom i have not me me from last 4+ months are actually surprised at my acheivement. I have kind of become a celebrity.

  12. jab

  13. lucy lou

    hi aimee, it does make a difference i’m afraid. i tried having a day off every week and i was just staying the same. even just one meal puts on a couple of pounds and the weight comes off slower. but the odd mouthfull of something won’t make a difference i wouldn’t have thought….

  14. aimee

    does anybody know if you cheat for one day a week will it make much difference? or even if i have a bite of something will it massivley make a difference? a quick response will be brilliant

  15. CoCo
