The Dukan Diet – 4 Steps to Weight Loss and Keeping it off Forever

Forget calorie counting and low-calorie diets with the mind-blowing Dukan Diet, which is a comprehensive 4 step diet to promote weight loss and keep it off forever, usually not possible with the short term GM diet meal plan. This is a well-balanced four-phase diet plan that not only helps in losing weight, but also acts as a guideline for healthy eating for the rest of the life. This diet was formulated by Dr. Pierre Dukan, a French physician while he was assisting an obese patient to lose weight without excluding meat from his diet. This is the exciting story of the birth of the Dukan Diet. The patient was ready to give up all other food except meat. So Dr. Dukan suggested him to have only meat for five days and to the doctor’s and patient’s surprise, the patient lost 10 pounds in five days. And this is how the Dukan Diet came into existence. The Dukan Diet is exceptionally popular in France and other parts of the world, and Pierre Dukan is one of the most-read authors in France and abroad.

The Dukan Diet

General Structure of the Dukan Diet Plan

Before getting on with the diet, it is important to know what is the Dukan Diet. The Dukan Diet is separated into four phases. The first two phases are the actual weight loss stages and the second two stages help in ensuring that the weight lost while the first 2 phases is maintained and stabilized permanently.

Phase 1 – The Attack Phase – The Dukan Diet attack phase includes only pure proteins that help in kick starting the diet. There are 68 high-protein foods you can choose from and eat as much of these foods as you like. This stage produces immediate and noticeable weight loss.

This phase helps you to achieve your true weight. In this phase, you will lose weight slowly and steadily by alternating between pure protein days and protein and vegetable days.

Phase 3 – The Consolidation Phase – This is one of the most important Dukan Diet phases which are important for maintaining the weight which is lost during the first 2 phases. At this stage, the body is extremely vulnerable and has a tendency to gain weight quickly. The consolidation phase has been specially designed to prevent the rebound effect that is experienced in most weight loss diets. In this phase, you can start eating the previously forbidden foods in small quantities along with 2 “celebration meals” per week.

  • During the cruise phase, you will lose weight, but at a slower pace compared to the attack phase, so don’t lose your enthusiasm.
  • Some weeks, you might see that you are not losing weight at all, or the scale is showing a slight increase in pounds. No need to worry, you are not gaining back weight. This is caused due to water retention in the body due to consumption of vegetables.
  • The real weight loss continues to happen, and it can be seen on the pure protein days.
  • This is the phase where your body will become shapely, supple and lean, and you will see a change.
  • It is also the phase where most people slip into temptation. So, stay strong, focused and motivated and don’t get deviated.

Consolidation Phase -The Transition Diet

The consolidation phase is the third phase of the Dukan Diet where you achieve your true weight, and this phase helps you maintain this new weight which you have achieved through a lot of efforts. It works just like the balanced 1200 cal meal plan but in a more effective manner. You should not go back to your old eating habits at this stage because then you are going to gain back your lost weight within no time. This is the stage when you have to be extremely careful because the body is most vulnerable at this phase. At this phase you consolidate the weight lost which finally leads to permanent weight stabilization.

  • The duration of the consolidation phase depends on how much weight you have lost.
  • The formula is 5 days of the transition diet for every 1 pound lost. So if you have lost 40 pounds, you need to follow the transition diet for 40X5 =200 days. If you have lost 20 pounds, you need to follow this diet for 20X5 =100 days.

Constipation – It has already been mentioned before, that restriction of carbohydrates in the attack phase of the diet also limits the amount of fiber intake, and this affects regular bowel movement. In order to prevent constipation, one must consume the recommended amount of oat bran daily and also drink plenty of water.

Relieves Constipation and clears the Digestive Tract

Bad Breath and Tiredness – Both this issues are caused by the formation of ketones in the body. But it is also an indicator that the diet is working for you. Nor everyone gets bad breath, and the intensity of the problem differs from person to person. It also enhances the build-up of plaque and tartar in the mouth, so it is important to brush your teeth properly and use mouthwash.

Kidney Damage – People opposing the Dukan Diet have raised this serious issue, but most people won’t experience kidney damage if they don’t have an existing kidney related condition along with high level of uric acid.

Induction Flu – This is the name given to a number of carbohydrate withdrawal symptoms. It makes a person feel weak, irritable and lacking in energy. But, these symptoms last for only a few days till your body gets used to the low amount of carbohydrates in the diet.

Fatigue – One of the most common side effects of the Dukan Diet is a feeling of tiredness and fatigue. But these issues can be effectively managed by drinking enough water throughout the day.


Vitamin Deficiency – Some people might experience a deficiency in vitamins if they do not bring variation to the meals and keep on eating the same foods over and over. In such cases, one can opt for vitamin supplements.
