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.

Unfortunately I have come off this diet. I really didnt feel well. My counsellor said I should have more energy but I just felt so weak. I am trying to stick to low carb foods and just being sensible. So far this week I have lost 2 pounds and feel much better as I feel human again. I know it will take a bit longer but as long as it comes off im ok with that. I feel that staring on the diet has given me the boost i needed to start eating more healthily. I decided to continue to drink all the water as my husband said my skin looked better and I knew that I didnt drink enough throughout the day anyway. I shall still come on the site from time to time to see how everyone is doing. Good luck to everyone who has started on this adverture. xxx

Hey all, newbie here. Have just survived day 1 on CD and have to say it's been a toughie! Everytime I feel a bit low though i've come on here and read success stories (i'm on page 34 now lol) and it keeps me going...I know it'll be worth it in the end.

I had an apple porridge this morning...really didn't like it (but i'm so hungry that i'm looking forward to it tomorrow ha), a chilli soup for luch (lovely) and a warm choc-mint shake for dinner (not bad but I was so hungry I didn't even wait to get rid of all the lumps!)

I'm finding it so helpful that i'm doing this with my sister in law, i've lost track of the amount of texts and calls we've had today...we both keep telling one another we CAN do this...and we can!

Not finding it to difficult drinking all the water, have had about 3 litres and I do find it takes the edge of my hunger.

Don't get weighed until next Wednesday but will keep you posted.

PS, you've all done SO well, its amazing reading how well xx

Had a terrible day yesterday. I felt sick all day long. Did my porridge up for my breakfast and it made me heave just putting it to my mouth. Couldnt stomach the shakes. Friend gave me a very low carb soup at lunch time as I felt really ill. Tried cottage cheese and salad when I got home, but couldnt eat that either. I think I am waining but going to keep trying today. My counsellor says I should have more energy as I loose weight but I just feel so lethargic. Its killing me to walk up the stairs I'm so breathless when I get to the top, my legs are still wobbly and I dont feel right. Am trying desparately to continue with this but dont know if I can stand feeling so ill all the time, miserable etc. I sat at work yesterday and cried and cried when I got home. Keep you posted. Good luck to Peachy.

Today is day 8. Went to be weighed yesterday and had lost 7 pounds. Dont know if I am pleased with that or not are my expectations too high? I am doing the 3 per day plus low calorie meal at night - its the only thing I look forward to. Cant stand the soup. The porridge just about palatable. I got some flavouring for my water yesterday as I dont do good with drinking all the water and it is making it a little easier to drink. I dont feel well still and am trying to decide if I've just ben ill anyway or whether its the diet. I dont know whether its just like the bodies response to a bit of a detox as use to have a drink of g n t most nights and not had any of those either. Not sure if I can sustain this. The weekends are awful. Wish me luck.

Today is day 4. I feel a little better today. Last night I felt awful with legs like bricks and a bit wobbly but has passed now. Looking forward to getting weighed on Sunday.

Day 3 of the diet. I didnt sleep well - dont know if this is related to the diet or not but legs feel like led weights and dont feel that well today. Know when I did Atkins some years ago felt like this on day 3 so am sticking with it. I dont really like the porridge or the soups if I am honest and the shakes dont seem to mix up right - maybe I am doing something wrong. I really look forward to my meal at nite. I need to stick with this but am finding it hard today.

Any hints and tips much appreciated. I am a comfort eater so trying to keep myself occupied on a night!!!

Im 10st so its hard to lose weight fast, cambridge helped me lose 11lbs in 11 days. basically a pound a day for me. its brilliant but i dont recommend exercise or doing stressful things - even walking long distances can make you really feel the hunger.
