Cambridge Diet

A liquid diet that may be too calorie restrictive for long-term success.

BACKGROUND Start the Diet Now Advertisement

With new diets hitting the market faster than we can lose a pound, it is not too often that you stumble upon a diet that has been around for more than 20 years. The Cambridge Diet has proudly clocked some years under its svelte belt. Developed in the 80s, it still enjoys a very loyal and passionate audience of dieters who have been successful at losing weight and keeping it off.

It is a liquid diet program that involves drinking 3 servings of the signature Cambridge Diet formula each day with or without food. The three servings provide you with protein (either 30 or 50 grams), carbohydrates, fat, fiber and your daily-required vitamin and mineral allowances.

About ten years ago, the Cambridge Diet added an additional product to their 330 Original Product. The 420 Food for Life product contains 100% of the required daily protein needs in 3 servings whereas the 330 Product contains 75% of the required protein. The protein source comes from whey and soy. Both of them are nutritional supplements that do not contain drugs, medicine, stimulants or herbs.

There are four ways for you to follow the Cambridge Diet: - The Fast Track: Consume 3-4 servings of Cambridge a day and no additional food. - The Alternate Program: Use 3-4 servings of Cambridge for one day with no food and then the following day, consume 3 servings of Cambridge with the addition of 400-800 calories of low fat, low calorie health food. Continue to alternate in this manner. - The Regular Program: Eat 3 servings of Cambridge 15- 20 minutes prior to each low calorie meal. Calories should not exceed 400-800 for the entire day. - The Regular Program 2: Consume 3 servings of Cambridge and eat one meal of low calorie food each day. Calories should not exceed 400- 800 calories for the entire day.

  • Cambridge Diet contains all the essential nutrients
  • Has a proven success rate
  • Safe for diabetics and those with high blood pressure
  • Its limited consumption of food may incite excessive eating
  • May be too calorically-restrictive for some individuals
  • Does not teach you to eat in a healthy and long-term way
  • Long-term weight loss may not be sustained
  • Calories might be too restrictive for exercise

The foundation of the Cambridge Diet is its signature line of shakes. They come in an array of flavors like chocolate, vanilla, eggnog, strawberry, cappuccino, banana cream and many more. The shakes come in two styles: The Original and the Food for Life.

The Food for Life product contains 51 grams of protein, 54 grams of carbohydrates, 3 grams of fat and 140 calories per shake. It also includes 100% of the Recommended Daily Allowance (RDA) of vitamins and minerals. The Original contains 31 grams of protein and contains about 110 calories per shake.

There is also a line of additional Cambridge products like soups, nutrition bars, and super oats.

When taken the prescribed three times a day, you'll only consume 420 calories. If you select to follow a plan that allows for food, you should not consume anymore than an additional 800 calories a day and these calories should come from low-calorie and low-fat foods like vegetables and lean proteins. If you are on the smaller side, it is recommended that you only consume an additional 400 calories on top of the 420 calories for the Cambridge products.

You are also strongly encouraged to drink at least 3-4 liters of water each day.


Since the Cambridge Diet is so restrictive, exercise should be done cautiously. It is not recommended to start a new strenuous exercise program while on the Cambridge Diet. Moderate exercise like walking or biking is useful once you start to lose weight, providing that it is approached with caution and not done with excess.


There is no question that The Cambridge Diet has been around for a long time. And in the process, many have had luck losing weight by following its strict dietary regimen. Since the diet is so low in calories, check with your doctor before starting it, especially if you have an existing medical condition.

The Cambridge Diet devotees swear by the diet's ability to help them lose weight as long as the program is followed correctly. But like most diets that rely on shakes or supplements to shed pounds, its potential for long-term weight loss and for instilling sound and healthy eating habits in you is not that promising.

YEAHHHHHHHHHHHH ... weighted in today .. i've lost a stone in two weeks!!! I cant believe it myself and can't stop grinning. In the past I've complained that as it was my time of the month, I couldnt stop eating but this time round I've managed to control myself and am so proud!! Today I even went out and bought a top in a size 16 and it fits nicely!!!!!!! The last time I did that was about 3 years ago. I'm not gonna even worry about how much CD is costing me now b/c I can finally see a light at the end of the tunnel.

Keep going people!!!!

Hi Sandra

Well done in taking that first foot forward, I know how hard it is and good luck. I'm on day 5 and have to say that the first 3-4 days was hard especially the weekend. As long as you drink lots of water you will be ok. Anyway good luck and hope to hear on your progress will keep you updated on mine weigh in on thurs.

Many thanks

@ Rhian, no the feeling does not last .. you will feel better in another day or so .. KEEP GOING!!!

I have one question for anyone/everyone though, has anyone noticed that when going to the toilet (not a nice question but anyway ....) that they are struggling to do a no. 2??? I'm finding that I cant go anymore .. which I'm sure is not good ... and if I do "go" .. it's a big strain and hurts like hell, I'm there for ages before anything will come out!!!!

couldnt wait so i weighed myself today .. and I've lost 6½ pounds so far ... oh what joy .. I even look smaller :) back later with an update ...

posted Apr 1st, 2009 9:20 am


Morning All .. I'm BACCKKKKKKK .. LOL .. yes I know what I said before about CD being expensive every two weeks BUT I've made some sacrifices and I'm now back on it. I've realised that I cannot continue the way I have been and this seems like the best way forward *better the devil you know and all that*. I started CD on Saturday and I can honestly say I'm trying my best to keep focused on what I'm doing.

Got weighed and had put back on ½ stone (not happy!) so there ya go .. this proves that I'm either a greedy git and have no willpower or the scales were wrong .. hmmm, I wonder which it is :)

I'll update in two weeks time .. or sooner if I feel like venting ..

*waves bye*

hi every one - have been on cd since april last year and have now lost 6 and a half stones. I do two shakes, and a healthy meal in the evening - this means i can still socialise by eating out whenever i want to - i just order fish/chicken with vegetables or salad. The benefits are fantastic - i feel i have much more energy, and have now found that i LOVE walking (before i would take the car a few hunred yards down the road!!). Still have 3 and a half stone to loose to my target weight, but this time, i can actually see light at the end of the tunnel, and hopefully i will achieve this goal before my summer holiday in august. Good luck to you all - and keep up the good work - YOU ARE WORTH IT!!!

hi all im new to this site but it seems the place for motivation lol!! i started the cd last thursday and had had my first weigh in today.... i lost 8 1/4lb!! i was REALLY HAPPY as i had a slip up over the weekend and went out and had a few vodkas!! lol

i find this diet great it seems to work but it takes a lot of will power, especially as my boyfriend is a lover of chinese food! but im going to stick to it as im going on holiday to Dubai in September and i want to lose 5 stones!!

good luck all

Hi everyone!
I've started the CD 21 days ago, after a great first week (lost 2,5 kg) suddenly statred lacking energy and consequently lapsing. As a result - last 2 weeks - no change. Still feeling motivated to continue, really want to lose about 3 stones by summer. Any tips on how to speed up the process and to resist "one-off slips" that could spoil the whole week? Thank you and good luck to everybody who is doing it!

@ Ishi .. well done on the weight loss .. but .. I'm not sure that you should be having the porridge, two shakes and then a meal .. that's not the objective of CD (I think) .. shouldnt it be the porridge, a shake and another shake for the evening or a meal in the evening? Please check it out. The gym does help speed up the weight loss though but I'm sure you shouldnt be doing that until probably the third week as the first two weeks is just liquid intake and you will probably burn more calories than you are taking in .. again .. check it out.

Good luck

Hi ive started the CD 9 days ago at 15.5 stones. I am now 14.11 st. I am drinkin my 3 litres of water every day but still feel so tired. My target is to reach to 13st. I have made a few changes. I will be starting the Gym in a few days and currently I am having the CD porridge in the morning along with 2 shakes and a meal in the evenin of complex carbs protein based with wholemeal tortillo lol... instead of just dropping the wieght i have decided ton use CD products to benefit from the nutrition and also work out in the gym to tone I doin the right thing? please advise anyone?????? thanx!!

Back on the CD. I lost just short of 2 stones before Christmas last year. I was back within a healthy BMI and although would have liked to have lost another stone, I called it a day because it was Christmas. Despite eating really well through Christmas and January, I did not really put any weight on other than a fluctuating pound or two. Then, disaster, I went ski-ing. Was eating loads of nice food and although I never put on more than a couple of pounds on holiday, I just could not stop eating when I got home and suddenly I had put a stone back on. I am back on diet since yesterday and am 3lb lighter this morning. I drank diet coke yesterday, I know you are not supposed to but I just needed it. Does anyone else drink diet coke out there whilst on it. Has it slowed you down. This time I am on it until I do get down to what I want to be so that is 1 stone 11lb away, as of today. This site kept me going last time and I hope it will do the same this time. Good Luck everyone. Helen M
