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.

Do You Know the Best Diet Shakes of 2016?

  • 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.

I have a question for those on Sole Source: I have been doing 4 weeks of Sole Source and then eating an additional 400 calories a day for week 5, and then repeating the cycle over again. I started on 12/29/08 and I have since lost 82 pounds. The problem now is that I have hit a plateau, and I have not lost in 2 weeks even though I have changed nothing. Does anyone have any advice?

Hi everyone, just had my 12th week weigh in and so far over 12 weeks have lost 57lbs. YEY!! Going on to sole source plus for a month, then working up the plans, as about 28 - 35lbs left to go.
This is the best diet I have ever done.
Keep going everyone

I swear by this diet if you follow it strictly. I lost 3 stone in 4 months last year. Unfortuntately I came off it around my birthday and completely fell off the bandwagon. But am back on it as of last Thursday. I have one treat night where I have a meal out (on weigh in day) and this doesn't affect the diet at all. I also find that I can't eat as much as I used to so it actaully does change your whole approach to food. Good luck to everyone on the diet...!

I tried CD last year for about 2 months and lost 9kg. Had stopped for about a year and sad to say I've gained back all the kgs.

Try to exercise and choose a healthy diet after the programme.

You guys who are taking CD, pls remember to drink plenty of water to prevent the liver and kidney from being congested.

.. forgot to say, exercise plays a big part in it for me as well. I am on SS but I havent been truly 100% with it but I do exercise EVERY DAY .. even if it's a 20 min walk ... exercise will help!!!

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 everyone, just come across this site and thought id leave a comment! im on day 12 of ss, lost 9 lb in 1st wk so very motivated to carry on, am finding it gets easier to stick to as time goes on and from thurs will be able to have the chocolate bars so am hoping will be easier again. have got a wedding in 4 weeks so am determined to stick it out, especially with summer on its way- know ill be gutted if i dont!! finding drinking lots of water ok, the evenings are when i struggle and think constantly about food!! but by doing something, like having a shower, i find the feeling soon passes. itll be my 2nd weigh in on thur so will keep my progress updated. good luck everyone!

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.

I have just completed my first week and have lost 13lbs which I am so pleased about but I am struggling today.. Its not that I feel hungry but its more about wanting some food, and I am shattered. Does this get better?

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!!!!
