What is Dukan Diet?


The Dukan diet was designed by Dr. Pierre Dukan, a nutritionist and eating behavior specialist having 35 years of experience in clinical nutrition. The Dukan diet is very similar to the system of HyperProtein. This diet offers a 4-bit phase protein and calorie and has the advantage of reducing the appetite. In addition, assimilation by the body carries great calorie burn allowing losing weight without losing muscle mass. It is basically a low carb, high protein diet but with unlimited eating. The catch is; you have to select the food from the provided list of foods.

The program also provides a maintenance phase afterwards regime to avoid gaining weight again when you return to the normal eating plan.

1) Pure Protein Attack Phase

In this phase, the user only eats proteins i.e. meat, poultry, fish, seafood and milk with 0% fat. This phase lasts between 3 to 10 days depending on the purpose.

2) Phase Alternative or Cruise Phase

It also works like the attack phase but with vegetables with a prohibition of the foods high in starch (potatoes, corn, peas, lentils, dried green beans). It works at the cruising speed and the vegetables are added progressively to proteins. The Cruise phase is the key time in the weight loss period, the one which will take you to your goal.

These two phases are alternated until the desired loss of weight (one kilo maximum per week) is achieved.

3) Consolidation Phase

We must return to offset the power supply, but it must be done slowly to avoid falling into the well-known ‘rebound effect’. The forbidden foods should be integrated into the diet gradually. We must have 10 days of consolidation for every kilo lost.

4) Stabilization Phase

You can eat normally as long as you respect two principles as always do a ‘Thursday Protein’ and eat 3 tablespoons of oat bran every day.

In the attack phase, upto 8 lbs weight loss is guaranteed.


  • Initially, you can lose weight quickly and then in a more controlled manner afterwards.
  • This system includes a long phase of stabilization.
  • Dukan diet allows 2 ‘gala meals’ per week in order to avoid frustration.


  • As the first phase only contains fibers, care must be taken with constipation.
  • The first phase has the same drawbacks that Hyper Protein system mainly has.
  • As in the first phase, you can eat eggs and meat at will which can run the risk of increasing the rate of cholesterol.
  • This diet is very strict and needs high dedication & commitment. If you lose your focus or stop it after 3 or 4 weeks, you will gain back the weight as quickly as you lost it.

Important Note

As with all the systems, you may run the risk of gaps, so it is best to see a doctor to check if you need to take vitamin and mineral supplements.
