What is the Dukan Diet?

The Dukan Diet is reduced – reducing the caloric content of meals to enable weight loss. In the case of the Dukan Diet, we are dealing with a high-protein diet, i.e., based on increasing protein intake. In addition, limit the consumption of fats and carbohydrates, and drink water often. In this diet, nutrition is divided into several phases – each of them allows the consumption of different products. It will enable you to reduce body weight quickly, but there is a risk of side effects. It is not a safe diet for everyone.

The Dukan Diet is one of the most popular reduction dietsTrusted Source. Independent use of diets without the supervision of a specialist is associated with the risk of the yo-yo effectTrusted Source. People who want to eliminate excess body fat should be careful when deciding on a reduction diet. Before starting it, it is recommended to consult a doctor or dietician.

The Course of the Dukan Diet – Phases

The Dukan Diet is divided into four stagesTrusted Source that should follow each other. The individual phases differ in duration and food products that we can eat.

The Dukan Diet brings the desired results in the first phase. A person following the Dukan Diet can lose up to five kilograms. The phase lasts up to ten days. People using the Dukan Diet can eat without restrictions and at any time of the day, but they must remember to eat only high-protein products.

Dukan Diet forbids eating fried foods and suggests eating steamed, grilled, or baked foods. You can eat turkey, chicken, rabbit, fish, offal, and seafood meat. Of course, the meat should be peeled from the skin. During the Dukan Diet, duck and goose meat cannot be eaten.

The Dukan Diet proposes eating poultry meats, lean dairy products, and chicken eggs for breakfast and dinner. You need to drink a lot of still water, preferably moderately mineralized. You can drink coffee, tea, herbal and fruit teas, as well as eat kefir and buttermilk.

Lack of fiber in the attack phase promotes constipation. There may also be problems with concentration and fatigue.

The second phase of the Dukan Diet is the cruise phase. It is the longest stage of this protein diet and can last up to several months – it all depends on how many kilograms you want to lose. The cruise phase lasts until the slimming person reaches the desired weight. The Dukan dieter loses about a kilo a week.

During the second phase of the Dukan Diet, nutrition from the attack phase is used, supplementing the menu with some vegetables. For example:

The Dukan Diet should look like this: five days of a protein-only diet and five days of a protein-only diet with vegetables. Sauces for vegetables should be based on paraffin oil or low-fat yogurt. Dukan does not recommend olive oil or vegetable oil sauces. Moreover, products from whole milling (flour, bread) are excluded.

After reaching the goal, i.e., the desired body weight, it is time for the third stage – the consolidation phase. The duration is ten days for each kilogram lost. The nutrition plan here is expanded to include more fiber products, including fruits, vegetables, bread, and bran. We can add roasted meats, cheese, and flour products to the menu. However, the new products can be consumed in limited quantities, and a protein-only diet is used once a week.

The task of this stage is to stabilize the weight and avoid the yo-yo effect. The duration of the third stage of the Dukan Diet depends on how much weight you have lost before. If someone has lost 10 kg, that person's third stage should last 100 days. This phase of the Dukan Diet is similar to phase two, but you can spice it up with fruits that do not contain too much sugar.

Dukan's Diet can be diversified with products containing carbohydrates: wholegrain bread, pasta, rice, potatoes, and lentils. These products can be added to dishes twice a week. Meat can be diversified with boiled ham, lamb, and pork. It is worth adding 40 g of cheese daily to the diet – choosing hard cheese and avoiding fermented cheeses is best.

The Dukan Diet allows you to eat two large meals a week at this stage. With these so-called “royal meals” – you can eat what you missed the most during the Dukan Diet.

The last stage of the Dukan Diet is the stabilization phase, i.e., the transition to everyday nutrition. The key is to carry out the attack phase once a week for as long as possible, preferably for the rest of your life. It is to enable you to maintain weight without gaining weight.

Due to the potential health consequences, the Dukan Diet can only be considered in young and healthy people. It is important to note that the protein diet should not be attempted alone but under the guidance and supervision of a specialist.

Safe Diet Principles

A protein diet puts a lot of strain on our bodies. To make it safer, it is worth using the following methods:

The Dukan Diet is based on pure proteins. As mentioned above, the slimming plan consists of four consecutive phases:

Each of these four phases of the Dukan Diet is based on a different principle of operation and is supposed to bring a different effect. They are all based on protein nutrition, alternating with vegetables. The key to the effectiveness of the protein diet is following the guidelines: eating meals as often as you like (before strong hunger sets in), not skipping meals, drinking fluids while eating, drinking at least 1.5 liters of fluids a day, limiting salting and eating only recommended foods.

Dukan Diet: Important Information, Phases, and Menu

Effects of the Dukan Diet

According to nutritionists, the Dukan Diet has some health benefitsTrusted Source and gives quick results, e.g., in men reluctant to lose weight. It is the so-called miracle diet. Used briefly, it is unlikely to harm a healthy person.

However, this is not a great way to eat for life. The Dukan Diet can burden the liver and kidneys and disturb the work of the digestive tract. Remember to do blood and urine tests to ensure your health before using the Dukan Diet.

Dukan Diet – Side Effects

The Dukan Diet puts a lot of strain on the human body. Only young and healthy people can use it.

The Kidneys

The composition of our body includes fats, proteins, carbohydrates, and water. If even one of these ingredients is missing, the body stops functioning properly.

Protein is a significant building block of our body, but if we supply the body with protein alone, we cut it off from the energy source. It then obtains it from adipose tissue, which affects rapid weight loss.

Unfortunately, you can pay for your health if you lose weight too quickly. An excessive amount of protein negatively affects our bodies. The kidneysTrusted Source may suffer first.

During the digestion of protein, the metabolic products are harmful compounds that the kidneys remove. It is a heavy burden on this organ and can lead to various diseases.

Protein products can also become oncogenic, which increases the risk of cancer. Long-term use of the Dukan Diet can be very harmful.

The Liver

The Dukan Diet also stresses the liverTrusted Source. This organ is responsible for obtaining energy from proteins. It is an inefficient process that will also make the body burn fats. The liver then works at top speed, which can destroy it over time.

The Brain

When using a protein diet, our brainsTrusted Source can also suffer. This organ needs glucose to function correctly. A deficiency of this compound will make us distracted, sleepy, and lose concentration.
