Dukan Diet

The Dukan diet (sometimes called the princess diet), which is very popular in many countries nowadays, has come from France. It was invented by Pierre Dukan, a French nutritionist and medical doctor. It took him about thirty years to popularize his diet and it became widely known only after the publication of the book named “The Dukan Diet”.

How Does It Work?

The Dukan diet is based on Pierre Dukan’s belief that eating protein-rich products can help to lose weight. So his diet is a high protein one. The main enemies of the dieter, according to Dukan, are carbs1 and fat.

The doctor gives the following reasons to consume more protein and to avoid carbs and fats:

  • Proteins are processed longer in the stomach than carbohydrates or fats so they stay there longer thus helping us to feel full.
  • Our body works much harder to digest proteins. It means that more calories are burned during this process.
  • Carbs have to be limited as they foster fat’s storage.
  • Fat should be avoided as it contains very many calories. It reduces appetite and can cause heart disease. In general, if you want to lose your fat you should stop eating it from any other sources.

The Dukan diet consists of four main stages: the attack (fast weight lost), the cruise (getting to the true weight), the consolidation (returning to a harmonious diet), and the definitive stabilization (lifelong maintenance).

What Are the Benefits?

The Dukan diet has many pros:

  • It will enable you to lose much weight pretty quickly.
  • You do not have to count calories or weigh your food.
  • Its prescriptions are very precise and understandable.
  • It heartens you to avoid alcohol, fat, salt, sugar, processed and refined foods.
  • It is easy to plan your mealtimes, which is very convenient.

Mostly, the Dukan diet is so popular because it helps to lose weight without counting calories.

Are There Any Health Risks?

Of course, if you are ready to actually follow the Dukan diet, you will lose weight. But you will have to eliminate many foods and it can lead to undesirable side effects for lack of some nutrients. A human body needs not only proteins but also many other matters, including healthy fats.

What is more, when a person starts losing kilos rapidly, it puts him/her at risk for kidney problems and nutrient deficiency. Losing over two pounds per week sometimes promotes muscle loss and gallstones2.

If you have constipation, dry mouth, bad breath or fatigue, you should skip out on the Dukan diet.

The diet has some other bad points: it is pretty expensive; you cannot follow it if you are a vegetarian; it is not flexible, etc.

What Foods Should Be Eaten?

There is the official list of foods that can be eaten as much as the Dukan dieter wants. You can find it on the website of Pierre Dukan. It includes different kinds of meat and offal, fish, poultry, seafood, dairy products, eggs, vegetable proteins, many vegetables, etc.

What Foods Should Be Avoided?

A Dukan dieter should avoid products containing much fat and carbohydrate. They are potatoes, beans, pasta, cereals, soft drinks, sweets, etc.

What Are Similar Diets?

If you got interested in the Dukan diet but for some reasons it does not suit you, take notice of the ketogenic diet or the Atkins diet. They are similar the Dukan diet.

Dukan Diet Plan

The Dukan diet’s plan consists of four main phases: the attack stage, the cruise stage, the consolidation phase, and the stabilization phase. The first one is the strongest, and the last one introduces your future healthy lifestyle. One should carry out all the stages in succession.

Here is the description of the Dukan diet’s plan:

The Attack Stage

This phase is very brief but it enables to lose from four to seven pounds in three – seven days by giving impetus to metabolism. During this stage dieters can eat all they want of seventy two food rich in protein (lean meat, poultry, soy, fish, eggs, etc). They also must get 1.5l water and 1.5tbsp oat bran daily.

The Cruise Stage

During the cruise phase diet will gradually move to their true weight. They continue eating protein-rich products and add twenty eight specific, recommended vegetables. They are expected to lose about one kilo per week though it depends on personal conditions.

The Consolidation Stage

This stage should help to prevent future weight gain. It prepares dieters for returning to their balanced diets. They can start eating bread, fruit, starchy foods, and cheese. Of course, they should not allow themselves more than several celebratory meals per week.

The Stabilization Stage

It is the maintenance phase of the Dukan diet. It seems to be very easy but it is also the most important because most people following a diet finally regain the lost weight. Now dieters can eat almost everything, but they have to follow these rules:

  • Once a week they must make a protein day.
  • Every day they must eat oat.
  • Every day they must have a 20 min walk. 

According to Dr. Dukan, if they do it, they will never regain their kilos.
