Cambridge Diet – It is amazing that after about 30 years the Cambridge diet is still so popular. Since the diet has been put on the market in 1984, there have been numerous scientific studies that largely disrupt old insights on diet and diet.

Is an old diet or responsible for losing weight? Or is the method that uses the Cambridge diet highly outdated and can you better look for a waste method of this age?

  • How can you really lose weight without diet?


The Cambridge diet was developed at Cambridge University by English food scientist Dr. Alan Howard and dates back to 1970. Since then, this diet has become very popular worldwide and especially in Britain.

It is said that the diet is its popularity due to many  positive experiences from people who successfully succeeded in this. I wonder if that’s correct. Of course, they will be lost when they have finished the Cambridge diet, but what happened half a year later with their weight?

The Cambridge diet will especially become so famous because of the marketing found. The makers of the Cambried Diet claim that:

  • After 3 days noticeable  weight loss of a few pounds
  • A better health
  • Suitable  if all other diets do not work

These are of course very beautiful  promises . I was wondering if they could make those promises true too. That’s why I researched how exactly the Cambridge diet is.

The idea behind the Cambridge diet is that you will replace carbohydrates and fats as much as possible with proteins . Therefore, the Cambridge diet is also called a  protein diet. The goal is to get the body in the state of ketosis.

What is ketosis?Simply put ketosis is a condition in which your body on starvation modestate. The calories that have been fed into food shortly ago. That is why the body tries to get the calories from somewhere else. The stored fat reservesare very suitable for this.

The body does this by breaking down fat and converting it to ketones. If you have high levels of ketones in your body, there is ketosis.

This ketosis is made possible by replacing the normal food with different Cambridge diet products such as  shakes , soups and ropes. These are ready-to-eat meals that are very rich in protein . These are claimed to be provided with all the necessary vitamins, minerals and fibers.

Self-cooking is no longer necessary, and of course it will take a lot of time and effort. However, this means that you  lose about 50 euros each week in the dietary products. Then I have not even included the consults for this.

According to Dr. Alan Howard, the fat reserves are being addressed and burned after 2 to 3 days by eating high-protein foods, combined with low calorie intake. This would allow you to expect  8 to 10 kilograms of weight loss a month!


The Cambridge diet products can not be bought at the store or ordered online. It is your intention to have a conversation with a Cambridge Weight Plan consultant. During this conversation you will be weighted first. Then discuss which program best suits your situation.

With the Cambridge Diet you can choose from 2 different programs :

  • Cambridge 500:  You only eat and drink Cambridge dietary products. This amounts to 3 meal replacements per day of a total of 500 kilocalories.
  • Cambridge 800: You eat and drink 4 meal replacements a day of a total of 800 kilocalories. You can also choose to use only 2 meal replacements + a light meal and any fruit.

The Cambridge diet products consist of:

  • Shakes  in powder form. Available in flavors strawberry, banana, toffee walnut, vanilla, chocolate and mango.
  • Soup  in powder form. Available in flavors vegetables, chicken & mushrooms, mushrooms, tomatoes and chili.
  • Pap  in powder form. Available in the flavors of natural and apple with cinnamon.
  • Ropes. Available in the flavors of peanut and cranberry.
  • Smoothies . Available in flavors cherry with strawberries and black currant with apple.

Furthermore, the Cambridge Diet Plan consists of 4 phases :

  • Preparation phase: You   eat a few days less than before before you really start losing weight.
  • Slimming phase : You eat 3 Cambridge meals a day and nothing else. However, it is recommended to drink 2.5 liters of water a day daily so that the waste can be disposed of properly.
  • Reduction phase : Here you will gradually replace Cambridge meals with regular meals.
  • Equilibrium phase : You must learn healthy eating habits and ensure sufficient movement.

The Cambridge 500 program should usually not last longer than 4 weeks. After 4 weeks, you are usually required, in consultation with your consultant, to wrap a rest period before resuming the program.

In addition, the first 14 days are not warned to exercise intensively because your body has to get used to the diet. Walking and swimming are allowed.


Even though the promises are very beautiful of the Cambridge diet, it appears that following this calorie-poor diet may be a little dangerous. Therefore, I hope everyone who wants to follow the Cambridge diet is extra careful.

Therefore, do not start the Cambridge diet before you are aware of all risks.


This dietary method has been a negative way  in the news several times . The low intake of calories would have led to various problems such as certain diseases, congested intestines, cardiac arrhythmias and even death ( source ).

Of course, all of these consequences do not have to be achieved directly by the Cambridge diet itself. Perhaps there was not a good listening to the accompaniment, or if there were insufficient meal replacements.

Nevertheless, on the Internet, there are enough experiences from people who point out that you have to be very careful about the Cambridge diet.


Especially in the first few days of the Cambridge diet, you experience a strong hunger feeling. This makes you feel futile and weak.

This hunger also causes a lot of extra stress, making you more of the hormone cortisol. Although the effects may vary between humans, it is generally believed that when there is too much cortisol present in the body, the risk of fever bumps increases ( source , source , source ).


A woman burns around 2,000 kilocalories a day a day. In a man this is on average 2500 kilocalories per day. With the Cambridge diet, you will be well below 500 kilocalories or 800 kilocalories.

Several studies show that following a diet with less than 1000 kilocalories per day, this can lead to muscle loss ( source , source , source ).

Muscles are very important, because they provide a great deal of total calories burn. The more muscle you lose, the less calories you will burn in rest. That means that after consuming the Cambridge diet, you consume less calories a day.

If you return to your old diet with the same amounts, you will get a lot more calories than you consume. These excess calories are then stored as fat. This way you’ll be back soon.


With a fast weight loss you also lose a lot of moisture . This can cause shortages of certain vitamins and minerals. Although these vitamins and minerals have been added to the Cambridge dietary products, the inclusion of these substances is unlikely to be optimal.

Dizziness and cramps in the arms and legs can be the result of this. These deficiencies can also affect heart rate.


In the 4th phase, we look at maintaining weight by learning healthy eating habits. But if you have overweight and learn healthy eating habits you will lose weight yourself. For this, you do not really need the first 3 phases.

That does not mean that the first 3 phases are a bad choice for all. People who have a lot of overweight can in some cases lose weight as quickly as possible.


As you eat so little, your energy level will decrease, making you automatically less in need of things. Sports are therefore not advised, as you get enough to get through the day.

Sports are essential for a healthy body. Therefore, it is very strange that by following this diet you are no longer entitled to the necessary movement.

A diet should provide more energy and no less.


In the end, Cambridge’s customers learn to keep their weight in the 4th phase, but then they will have to eat healthier than how they did before they started the Cambridge diet.

It is only the question of whether the Cambridge diet supervisors spend enough attention on their clients at this stage. In the fourth phase, the customers stop eating the expensive dietary products of the Cambridge diet, which makes it hard to earn money.

RISK # 8: Larger chance of clogging (constipation)

Because you do not eat enough fibers, you can get clogged. Especially in the first phase of the diet, where you mainly eat liquid, there is a chance of clogging.

How can you really lose weight without diet?

If you want to lose weight 4 to 8 pounds a month and are willing to fight for hunger feelings, like keeping strict rules and spending a lot of money on dietary products and guidance, then the Cambridge Diet may be something for you.

It may not be the funniest or healthiest diet, but there are enough people who have made a profit and are now slim.

The Cambridge Diet gives you hold, because everything is set for you. And that brings us to the next problem: the bridge between the Cambridge diet and the ‘normal’ life.

The Cambridge diet hardly promotes a healthy lifestyle. I do not think you’ll want to grab diet hooks for Cambridge for the rest of your life as soon as the holiday pillars are off.

If you want to eat healthy, treat yourself to social situations and especially not feel hungry, you may be better off with the protein diet or the low-carbb diet .

With the carbohydrate poor diet;

  1. Do not burn your muscles
  2. You will get all vitamins, minerals, fibers and phytonutrients
  3. Do not have to starve for a second
  4. Keep your breath fresh
  5. You can endlessly vary with recipes
  6. You get more energy, which makes you more comfortable to move
  7. Get enough fiber to prevent clogging

With a low-carb diet you can lose weight up to 8 kilos per month.
