Cambridge Diet

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

Top Rated Diet Shakes of 2016
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 started CD last week monday 23rd of Feb and last time i weighed six days in had lost 6lbs...but that night i went to a party and lost all my willpower and had everything from pizza to fried chicken...i felt terrible because i went prepared (i had a shake in the car) and just lost it.
i re-started the next day and weighed myself the day after and i had gained..i dont know if its the meal i ate, or if i am seriously beating myself up about nothing but i am so upset with myself now..i am on sole source and should be moving to add a meal in 4 days but its the hardest time of my life right now.....and i just dont think i can make it.

Hi everyone, I have just done the first week of CD and lost 9lb. Amazing. I was really inspired reading about you Jane as I have about 7 stone to loose. I have had a lot of negative remarks from some friends. A coupld of friends started it four weeks ago and have lost 2st 4lb and 2st 6lb each. It really is amazing if you stick to it. After the initial couple of days of headaches I feel marvelous.

Hi Fiona K ,

Is it 12.5 pounds in 1 week?.Are you doing any excercise as well.

I have been on this since 25th Jan. I have lost 15 lbs as of last weigh in (5th Feb), I get weighed tomorrow and hope that the rapid loss is sustained.

For Jane:

Thanx Jane for your advise and your achievement is outstanding - well done. Only i can hope for such a great result. I have been feeling better. Headaches & tiredness gone and i even managed to go swimming this morning. I havent cheated once. The water situation isnt too good but i went back to my counseller and got some of the berry mix and thats fab. A bit costly at 6.50 but think it will last for a while. My weigh in is in 2 days so i will feedback and let you all know how i got on :)

hi fiona K: i have approximately 8 stone to loose. i have been on the cd since may of last year, and have currently lost 6 stone. I have achieved this by having two of the tetra pak shakes a day, and then a meal on the night - usually consisting of fish/chicken with salad/vegetables. This way, i am still able to socialise with friends and family, and dont feel i am missig out on anything. I have had two holidays abroad at "all inclusives" during my diet, and of course Christmas. Each time, i have put on a little weight, but have soon got back onto the diet.

I cannot tell you how better I feel in myself - not just when i look in the mirror but healthwise too. My doctor always told me i needed to excercise - walk, etc, but at my previous weight i was unable to do so. Just after xmas, i treated myself to an i-pod, and now there is no stopping me!! Walking today with the snow on the ground, and the (weak) sun on my face has been fantastic - whereas before i would have taken the car 100 yards down the road.

Hopefully, i have changed my eating habits, and along with the fantastic support of my councillor i will not only be able to reach my goal, but also maintain my weight loss permanently.

Hopefully i have given you some incentive, dont give up - you really are worth it!!

I just started CD on Tuesday so now finished my second day. I am struggling. Sore head, bad breathe, feeling very lathargic.

I knew this would be hard but god. Its Tough. I need to lose at lease 6-7 stone. I didnt like the porridge and the shakes aren't the best. So i am restricted to 2 soups and a bar a day. I am scared that i get so bored with them.

Can anyone give me advise.

i've been on the SS CD for 11day's now... the first 7day's were awful, i started the diet on a saturday and due to shree determination the 1st aturday was fine... but the 1after was awful and i just gave in... i supplemented 1off the shakes for a healthy meal (fish and salad) i went to my weigh in the nx day and i must say ... the meal i had the night before didn't make a differnce at all... i still lost 5lbs... so i haven't been absolutely loyal to the CD but a heatly meal does not go astray...

I also feel this diet feel's like you phisically starve yourself... any1 who stop's eating and just has a calorie intake of less then 400kl per day is obviously going to loose weight... so CD or no CD this is common sense... the CD is just soooooo expensive... what happens once u start to eat... obviously ur gonna put the weight gradually back on...

so is is worth paying all this money for it... or would u rather opt for the cereal diet??? i would say any food intake at less then 400kl /day would make u loose weight...

so overall i really don't think this is a good diet at all... afterall just starve ur self or have 3cereal bowl's a day - this work's the same way !!! and alot cheaper (",)

Fantastic for good fast weight loss but requires extreme determination and willpower

I heard that if some one is on sole source programe and use tea with lemon or use leamon peace in tea then it can negate the diet effect on your body.I am on CD and drink 2 cup of green tea with lemon.Is it safe to drink or i should stop.

Thanks Kathryn,

I will definitely try next month .. cravings have now gone (even though monthly has not arrived :( ) but I feel much better. I got weighed at this week (but not my counsellor) and I'd lost 3½ lbs so I must be doing something right .. :)

I will continue with more determination now ..

Keep up the good work people ..
