Dukan diet: phases, allowed foods and sample diet

If you've decided to lose weight, you might be surprised at how many different types of diets there are. But how do you navigate them all and find the one that works for you? In today's article, we'll focus on the Dukan diet, which has gained popularity thanks to its fast results and clear structure. How does the Dukan diet work, what foods are allowed and what can your diet look like? Let's take a look at everything you need to know before you decide to give this diet a try.

What is the Dukan diet?

The concept of the Dukan diet may sound like something completely new to you, but as you'll soon discover, it is it's a type of protein diet that's specific to four progressive phases. The diet bears the name of French physician and nutritionist Dr. Pierre Dukan, who introduced it in his book I Don't Know How to Lose Weight. This book has become a bestseller and has been translated into 14 languages. The Dukan diet has gained popularity especially in France and the UK. What is its magic?

The Dukan diet is based on eating two food groups - protein-rich foods and vegetables. Different foods are allowed in each phase, with the basic principle being high protein intake, low carbohydrate and fat restriction. This system aims to reduce hunger and promote fat burning without losing muscle mass. The diet is based on unlimited consumption of permitted foods, so you will not suffer from hunger. The Dukan diet has become popular due to its clear structure and rules - giving people a sense of control over their eating and a clear path to achieving their goals.

The phases of the Dukan diet

The Dukan diet is specific in that it does not limit the amount of protein you can consume in all phases. It allows you to consume as much as you want, because protein supports satiety, speed up metabolism and help maintain muscle mass during weight loss. The diet is divided into four phases with clearly defined permitted foods and nutritional guidelines. Gradual adherence to these phases is essential to achieve effective weight loss and weight stabilization without the risk of the yo-yo effect.

1. Attack phase

The first phase, often referred to as the starter phase, is designed to prepare the body for change - this is theadaptation phase, which will kick-start your metabolic processes and adjust your body to the new way of eating. The phase focuses on rapid weight loss using a pure protein diet to trigger fat burning. This phase is essentially very similar to ketodiet, the body goes into ketosis and fat burning occurs instead of carbohydrates.

During this initial phase you can choose from 72 allowed foods, although the basic principle is simple: Eat lean proteins that contain minimal fats and carbohydrates. Dukan recommends consuming 1.5 tablespoons of oat bran a day - not ground, but whole quinoabecause of the fibre, which helps to cleanse the digestive tract. Oat bran is key here to aid digestion.

Your diet thus consists of meat, low-fat dairy products, oat bran and selected permitted ingredients. At this stage, vegetables and other side dishes do not belong on the plate yet - the body shouldshould focus on the protein base that will prepare it for effective weight loss in the second phase.

Recommended length of the first phase:
The length of the first phase should be tailored to your goal. The maximum duration is 7 days, but the optimal range is 2 to 5 days, depending on how many kilograms you want to lose during the diet:

  • 2-3 days for a target weight loss of up to 5 kg.
  • 4 days for a weight loss of up to 10 kg.
  • 5 days for a loss of up to 15 kg.
  • 6-7 days for a target weight loss of over 20 kg.
6-7 days of weight loss for weight loss
  • Lean meat: beef, veal (excluding pork and lamb).
  • Poultry: chicken, fowl, turkey.
  • Fish: salmon, carp, trout and others.
  • Tuna: in its own juice.
  • Offal: for example, liver is also allowed.
  • Dairy products high in protein and low in fat: cottage, kefir, fat-free white yoghurt, cottage cheese, processed cheese, milk (in limited quantities).
  • Alternative protein sources: tofu, eggs.
  • Spices and herbs: to flavour food, without added sugars or oils.

Preparation tips:
Dukan recommends using no more than 5 drops of oil to prepare meat, and grilling, baking or boiling meat, not frying.

Drinking and exercise:
In the first phase, it is crucial to follow a drinking regime and drink at least 2 litres of water a day. At the same time, it is advisable to include light physical activity - for example, a walk. Avoid vigorous exercise so that the body is not overloaded, but regular movement will support your results and adaptation to dietary changes.

Eat foods that contain no sugars and only a minimum of fats.

2. Weight loss phase (Cruise)

In the second phase, real weight loss and reduction of excess fat occurs. The goal is to gradually approach the dream weight while still sticking to a proteinPhase One's protein base, to which low-starch vegetables are now added. Together you now have 100 foods to include in your diet.

In this phase, the dietary rules are still strict but more variable. In addition to protein, you add 28 vegetables to add variety to your diet, while adding nutrients without unnecessary calories. Also add 1.5 tablespoons of oat bran to your diet each day to help your digestive system. The key is to drink plenty of water and combine your diet according to the tried-and-tested formula of alternating pure protein days with vegetable days.

Alternating days
In the second phase, it is recommended to divide the days into pure protein days (when you consume only protein without vegetables) and protein days with vegetables. The most common pattern is alternating 1:1 (one protein day, one vegetable day), but you can choose other combinations, such as two protein days and two vegetable days or 3:3, whichever works for you. The rate of weight loss tends to be about 1 kg per week, so you can adjust the length of the second phase to your target weight loss.

Length of second phase:
Stay in this phase until you reach your goal. With this rate of weight loss, the length of the second phase can be individuallyThe more pounds you need to lose, the longer you stay in it. Movement is also crucial in this phase - the more activity you include, the faster you will achieve results.

foods allowed
  • All foods from the first phase.
  • Plus 28 vegetables: lettuce, cucumbers, tomatoes, peppers, green beans, kale, carrots, celery, broccoli, cauliflower, zucchini, squash, spinach, cabbage, mushrooms and more. (However, avoid vegetables with higher starch content, such as potatoes or sweet potatoes).

3. Consolidation phase (Consolidation)

In the third phase, the body slowly returns back to normal and gradually gets used to maintaining the new weight. Dukan designed this phase to protect against the yo-yo effect that occurs when the body tries to return to its original weight after rapid weight loss. This effect is common because after significant weight loss, the body tends to regain fat stores. The consolidation phase is therefore crucial for stabilizing the newly gained weight and establishing healthy habits. A key element is the adherence to one "protein day" per week, when returningto pure protein meals to keep the body stable at the new weight.

Movement is even more important at this stage - regular exercise will not only strengthen the body, but will also keep your metabolism active and contribute to the long-term success of the diet.

Allowed foods
  • One fruit a day (except bananas, grapes and cherries, which have a higher sugar content).
  • 1-2 slices of whole grain bread per day.
  • More dairy products, including hard cheeses up to 100g per day.
  • Side dishes, such as rice, potatoes or pasta, once or twice a week.

Meal and reward food:
Once a week, you can indulge in a "reward" meal to suit your taste, such as a favourite cuisine or a dish you otherwise deny yourself. This small concession is designed to keep you motivated while not undermining the long-term effect of the diet.

4. Stabilization phase (Stabilization)

The fourth phase of the Dukan diet is no longer a classic "diet phase" - rather, it is a return to runningDukan is a return to normal eating that allows you to maintain your weight without significant restrictions. In this phase, you can eat as much as you like, but with the knowledge thatknowing that a return to unhealthy eating could lead to weight regain. So the key is to find a balance between healthy eating and flexibility in your diet. It is advisable to consume plenty of protein, vegetables and drink plenty of water. This will ensure that the body is kept in balance and you can indulge in the occasional sweet or other favourite treat without significantly affecting your weight.

Recommendations for the fourth phase
  • Solid dietary basics: While you can indulge in everything, try to stick to the principles of healthy eatingA healthy diet should include plenty of protein, fiber, fruits and vegetables, and limit excessive sugar and fat intake.
  • Occasional "munching": If you occasionally indulge in something sweet or less healthy, it's not a problem as long as you stay in an overall balanced regimen.
  • Protein Day: Dukan recommends keeping one protein day per week (for example, Thursday) or at least once every two weeks. This day will help control weight and promote metabolic stability.
  • Drinking.
