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.

Has suited me very well. Easy to take meals to work and even with having to eat the odd meal. I have lost 18 pounds in 6 weeks and intend to lose one more stone. After I reach my goal weight, I will continue with the meal supplements as it fits in to my lifestyle so well and saves the dreaded supermarket shopping!!

I have been on ss 3 shakes a day for 11 days got 21 pound to loose and lost 11 already 10 to go! First few days were awful but feel fine now! Obviously it's hard you have to stay focused! I am back in my pre pregnancy jeans already! I think you have got to be sensible with what you eat when you finish the diet! I have never been this successful on any diet before! Give it ago x

I am on a CD now for one week. I have cheated, yes. :-) but still I am satisfied with ongoing process. I hate chicken/mushroom soup as to me it is totally oversalted. Most of the soups are... I can hardly eat it. But other than that I am doing fine and kilos go down... I will see how will it go on... and if I can manage to reach my goals. and especially I am inquisitive to see how will I get back to real life without gaining the weight back. wish me luck.

Hi Everyone, I have been doing the CD diet for 2 months now and lost 2 and a half stone. I have been having 4 shakes a day on the soul source and have just started reintroducing food for the last couple of days. I now have 3 shakes and one small salad (under 200cals). I am actually finding it harder now I have introduced food as when I was just using shakes I didn't have to think about preparing food etc. Please tell me this gets easier :)

I still have 6 weeks left on the diet so I am hoping to lose a lot more!

I dono, loosing that much weight without a doctor or a dietitian, my mom did this and lost lots of muscle, regained the weight after. Because of that her GP has her on PronoKal instead, you don't regain the weight or lose body muscle

I don't know if anyone is interested but I've just embarked on the cambridge diet and I'm keeping an online diary/blog for anyone thinking of doing it. A friend of mine did it and lost two stone in under two months.

Don't seem to be many men on here; hope I'm not the only one.

I've always been overweight and started out at 22 1/2 stone. My partner and I decided on doing the CD but because my BMI was over 40, I needed a doctors approval. To sort of get in training, I decided to replace one or two meals a day with a slim fast untill we could start on the CD together.

My partner and I started the CD one week ago to the day and have been having just the 4 shakes and so far, so good.

Withinin a couple of days, my partner said she was losing a lot of fluid from around her ankles and legs and I've noticed that my finges seem to be less chuby.

I've been hopping on the scales now and again and seem to have lost almost a stone.

No real hunger pains unless I smell french fries and then I can hear my stomach moaning, and I do miss bread.

The big problem for me has been the amount of fluid you have to drink. I don't drink much as it is and this has been a real killer for me. However, CD have some poweder flavouring that you can pop into water and it just gives a hint of taste. Thats made it better for me. Now, as soon as I feel hungry I have a couple of gulps from my water bottle and that seems to keep me going to my next feeding time.

The worst time of the day is the evening when I would normally settle down to watch TV. Its then that I miss not eating a snack and so I try to keep busy with my hobbies to take my mind off food - it seems to be working.

Over all, nowhere near as bad as I thought it would be and I'll hopefully stick with it.

EXCELLENT. It very defintely works. I only like the Vanilla Shake. I mix it with approx 20 mls of really cold water (from the fridge)as I prefer a cold & milder taste PLUS 3 teasp Psyllium Husks for fibre and which gives it a slightly thicker texture PLUS 2 teasps of Spiulina. I then beat it well and drink immediately. Deeelicious. The soups? I like the veg and Oriental one. I mix with 10mls of very hot water PLUS lots of parsley and a few green veg. I then beat it as before...with an electric blender. The bars...the cranberry one is my favoutite. I cut it up into small pieces and nibble it with a cup of green tea. Persevere. It's worth it.
