Cambridge Diet Review (UPDATED 2024): Don't Buy Before You Read This!

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

Top Rated Diets of 2024
What is it?

The Cambridge Diet is a weight loss program offering pre-packed meals, counseling, and low calorie meal suggestions. It’s considered a VLCD, which means it’s a very low calorie diet.

One can select between 415 to 1500 calories depending on one’s weight loss goals, gender, and tolerance. Consultants are offered not just to guide, but to recommend what calorie limit one should follow. There have been numerous diets observed by our experts, and the highest rated one has been  the 18Shake Diet. It offers a diet pill and meal replacement shakes that aim to reduce appetite for hours, all while providing fat burning effects with its all natural ingredients. More information about the 18Shake Diet can be seen in the link here.

Cambridge DietIngredients and Side Effects

Here are some noteworthy ingredients added to their prepackaged foods:

Skimmed Milk Powder


Guar Gum

Refined Fractionated Palm Oil

Acesulfame K




Dried Glucose Syrup

Silicon Dioxide



Guar Gum:Fiber extract taken from the guar plant. It’s used as a general thickener in processed foods, as well as a laxative.  It can promote side effects that include:

         • Diarrhea, gas, and loose stools.

         • Indigestion, nausea, and stomach pains.

Acesulfame K: Artificial sweetener around 200 times sweeter than standard sugar. A study by PLOS One found that:

“Long-Term Artificial Sweetener Acesulfame Potassium Alters Neurometabolic Functions”

This study showed that in mice there was an effect on insulin and leptin levels.  The same study added:

“chronic use… could affect cognitive functions, potentially via altering neuro-metabolic functions”

It also has shown the potential for other side effects according to a review by the Oxford Journals:

“long-dated function on the adult’s sweet preference”

This study was conducted on mice that were given their mother’s breast milk or amniotic fluid in birth, and their preference for sweets changed.

Sucralose: Artificialsweetener that can be around 1,000 times much sweeter than sugar. It has been used controversially since some studies have shown it to be potentially dangerous. One such study was performed by Duke University and it revealed:

“numerous adverse effects”

“reduction in beneficial fecal microflora, increased fecal pH, and enhancedexpression levels of P-gp”

This means the body considers it a toxin, and it reduces healthy bacteria which helps support the immune system according to this clinical study.

Carrageenan: Thickener and binder extractedfrom red seaweed.The University of Iowa ran a study which showed:

“carcinogenic properties of degraded carrageenan”

“ulcerations and neoplasms in association with exposure to carrageenan”

This has shown the possibility for causing serious issues in the body.

The link provided here has the top 10 ranked diets of the year.

The types of foods offered by the Cambridge Diet are meal replacement shakes, bars, pasta, rice, soups, desserts, and other snacks. According to the official website:

“products contain the vitamins and minerals you need for balanced nutrition and healthy weight loss”

Most of what one eats will be the prepackaged foods. This can make it easier to handle a caloric loss, as the foods are specially formulated to be lower in calories. There are also 6 steps outlined one must follow, though where one begins depends on what the counselor advises. Here are the steps:

• Sole Source: 3 to 4 prepackaged foods are eaten a day. The Sole Source Plus option allows for 3 prepacked goods alongside meal of 200 calories, or 4 of the companies meals with 200 ml of skimmed milk.

• 2nd Stage: Protein rich meals are added as well as some skimmed milk and vegetables alongside up o Cambridge meals. It’s typically limited to 810 calories a day for a week long period.

• 3rd Stage: 2 of the meals, some milk, and a 1,000 calorie a day limit. This is enforced for 2 weeks.

• 4th Stage: 2 prepackaged meals, some skimmed milk, and more regular meals.

• 5th Stage: One Cambridge meal and breakfast, lunch, snack, and dinner for a total of 1500 calories.

• 6th Stage: Once your heathy weight is reached, this stage helps maintain results. One prepackaged meal a day is recommended alongside continued support from a consultant.

It’s unclear whether or not the consultants have any background in diet and nutrition. It’s unlikely however that they use real certified dieticians, which can be potentially dangerous or lead to wrong advice. Our experts have analyzed many diets and have ranked the top 10 in the list here.

EDITOR’S TIP: Combine this diet with a proven meal replacement such as 18 Shake for better results.

Cambridge Diet Quality of Ingredients

Since the beginning of the program asks for a majority of foods to be selected from the company’s prepackaged foods, it’s important for the ingredients to be wholesome.

Unfortunately, they use artificial sweeteners and cheap thickeners often used to replace fiber. These kinds of additives can actually make weight loss harder, as studies have shown they may cause metabolism disorders as well as other side effects.

It’s also difficult to understand what kind of help is provided by the counselors, which remains to be seen whether or not they are actually certified to give health and nutrition advice.  The link provided here has a list of the highest rated diets.

A review on the Cambridge Diet was performed by the British Dietetic Association, and they have listed possible side effects which include:

“bad breathe, a dry mouth, tiredness, dizziness, insomnia, nausea, and constipation”

They also advise for medical support when a person is to receive less than 600 calories, which some plans offered by the company suggest only 450 calories a day. It’s unclear if the counselors offer any support for this type of reduction in calories.

The Price and Quality of Cambridge Diet

The price depends more on how often once decides to use the prepackaged meals. The official website states it will cost per week 48.30 pounds, which rounds to a weekly price of $63.46. Since this is a UK based plan, no consultations are available outside the US. In fact, on the official site there is a map where support and availability is offered, and there are no listings for the US.

The quality of meals is poor, as the additives included are often found in processed foods. It can also be expensive to have to keep using the company’s foods, as the final stage of maintenance requires one pre-packaged meal a day.

Business of Cambridge Diet

The contact information for the diet is as follows:

Phone Number: (44)(0) 1536 403344

Address:Stafford House, 10 Brakey Road

                   Corby, Northants, NN17 5LU

Email: [email protected]

The official website lists how to become a paid consultant for the company. Nowhere in the job skills is there any notice for people to have a background in health and nutrition. The company only asks for people with a background in sales who are organized and can plan ahead.

This means that it’s likely the people who are meant to give support have no skills in helping people with weight loss. The link cited here has the top 10 ranked diets.

EDITOR’S TIP: The top 10 list of the best diets is available here.

Customer Opinions of Cambridge Diet

Here are some direct quotes from user reviews:

“not the best diet health wise… nails went brittle thin, hair began to thin rapidly”

“never felt full, I always felt hungry”

“Having a bad time with motivation”

“the first few days are the hardest”

Though there were some weight loss results for people, there were also issues due to a lack of calories. Many felt weakened, less energetic, and much more fatigued than usual.

Some also had symptoms that are clear signs of nutrient deficiencies such as brittle and weak nails, thin hair, and increased stress. This was often the case for people who attempted this diet. 

The top 10 ranked diet plans can be seeninthe link provided here.

Conclusion - Does Cambridge DietWork?

The Cambridge Diet is similar to other diet plans which offer pre-packaged foods. There’s also counseling offered, but it’s clear that the support is from people who are more business people rather than nutrition experts. Many of the foods offered have processed ingredients, though they are low in calories. Reviews have been mixed with some experiencing health issues and hunger. Though a low calorie plan like this can work, any reduction in calories can result in weight loss. There’s nothing special added to the prepackaged foods which isn’t found in a standard processed meal.

Our experts have performed many reviews and have discovered that the most effective diet is the 18Shake Diet. It provides a combination of a meal replacement and a diet pill. They both provide only natural ingredients, no stimulants, and no unwanted artificial or additives. Its effects include appetite suppression, increased fat burning, and more. When used together it enhances weight loss at a faster rate. Customers have also left positive testimonials on the official website.

The 18Shake Diet is also supported by a full 30 day money back guarantee. This allows for people to try this product risk free, and with no questions asked. More information about the specifics of the 18Shake Diet is available here.

hi i'm now going into my 3rd week of the cd, i was told at the beginning that the 1st few days would be really difficult, unsure why but i found it ok, i lost 10lbs in my 1st wk and my 2nd weigh in is tomorrow fingers crossed. if you do feel hungry i suggest you eat vegetables def not carrots tho as they have lots of carbs in them if having salad and you need to use a dressing use balsamic vinegar. good luck everyone and well done to those who are managed their 1st week as i know it can be difficult x

started the cd 3 weeks ago and i must say this is not for the weak people. On the first week I cheated nearly everyday with atleast a spoonful of food... I'm telling you it is sooo tempting just to eat... I'm sitting here just now one day before weigh in and on my third week and I've been cheating for the last three days... just felt really hungry and ate everything I felt like eating, drank cola the usual.. drank alcohol last night for the first time since I started and I swear to god I drank three glasses of vodka and was drunk lol Happy days... me and my mate thats also on the diet just decided (quite dangerous) so don't try this at home haha Just honestly this diet is amazing when you stick to it but the best tip I think I can give anyone is just to drink as much water as possible to stop you getting hungry and remember that determination you have during the day when your so up for loosing weight and nothing will stop you... because your not actually hungry all the time just at night when your chilled and theres nothing to do but watch tv and you feel a real urge to eat but just remember that feeling in the morning when you stuck to your diet the whole day before... And most of all how awful you feel when you've cheated... :( Not nice you feel like a total looser because you really have to base alot on this diet to be able to do it... I myself have pcos which is a condition that basically makes you fat.. Not with everyone but in my case I have every symptom going.... Lucky me eh :) But anyway to cut a long story short I'm 19 years old and just looking really for that confidence thats going to turn me from bubbly fat girl with a shit dead end job to the girl next door with a straight head and prospect... I honestly think that this diet and weight loss itself will change my life... Not been the greatest so far and to be honest its not all been weight but at the end of the day I and all of you are only going to live once !!! PLEASE DON'T TAKE THAT LIGHTLY JUST REALLY THINK ABOUT IT ! Do you actually want to go through your life thinking how much happier you would be slimmer or do just make it happen girls :) First thing I recommend before you start is to to take a few pictures and then have a look at some new ones even as little as month after you start and see this difference.. you feel like a new person too ! Just make sure your doing it for you xxxxx

I'm on my 3rd day of the CD. Day 1 was fine. Day 2 all I could think about was food I hardly ever eat - pies, pizza, lasagne. Today I'm a bit better. Still thinking about food, but not as bad as yesterday. Trying to drink lots of water - not easy in winter.

I want to lose 15kg.

I started the CD 7 days ago. I struggled with hunger pains the first 2 days but after that I am fine. I have 3 shakes a day and a normal meal. In between I eat cucumbers and maybe some yogi 0% if I haven't had milk. I feel soooo much better and wake up in the morning without that tired feeling and I have certainly got rid of the excess bloating. tomorrow is weigh day so I am looking forward to that to see how much ive lost. I also have hypothyroid so I don't expect very speedy results. I will try to stick it out as long as I can.

I have just started the diet yesterday and i find it ok so far? i have tried to stop cravings and my husband is all over my kitchen cooking nice meals which was quite tempting...lol but i have stood by the diet so far. Today is my day two and i am finding it ok. although have started having the headaches but i am trying to control it. i wore a shirt today that i havent tried on in two and it fits ok, this is motivating me to stick to the diet, i also realise that anytime i feel hungry i just drink a glass of water which helps alot. anyone starting the diet that needs a buddy am avaliable.

I have been on the ss plan for 4 days, finding it great. Not been hungry at all just really craving some solid food!

I cheated by weighing myself tonight but Iv lost 16lbs in 4 days :)

I'm 16 stones and my goal weight is 10 stone, if I carry on losing like I am I'll get there in no time :)

I honestly love the plan, think it's alot easier to follow and stick to than healthy eating diets like weight watcher etc as food is just not an option so you don't get tempted to cheat with that slice of chocolate cake or fly chip. With Cambridge you know if you decide to cheat all your body will come out of ketosis and that 4 days of that struggle is totally ruined.

My only problem is for two days I've only had time/remembered to have one shake which I know is really bad for me but as of tomorrow I am going to set my alarm on my phone as a reminder to take my shake!

posted Apr 10th, 2011 5:34 pm


This is an excellent diet. i lost 7 stone in about 5months i had the odd day off! i was 18 stoneandwent to 11 stone. as long as you dont go back to your old eating habits u willbe fine. but you have to be really wanting to lose the weight or you will not want to be drinking shakes everyday. best thingi ever did + worth every penny. good luck to you all.

I lost 45 lb on Cambridge in five months late '82 to spring '83. It did help me change my eating habits and I kept the weight off for two years. I was badly injured in an accident and spent the next five months on my back, gained 20 lb. I am now 90 lb overweight (my wife is a great cook but it's not her fault I eat too much ...) and have decided it is time to get back to correct weight. After reviewing many possible diet plans, I'm commencing Cambridge again because I know it works.

BACKGROUNDBACKGROUND 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 Pills of 2024?

  • 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.
