The Dukan Diet is a low carb, low fat, eat as much protein as you want diet. The diet is followed in 4 phases called Attack, Cruise, Consolidation and Stabilization.
Attack Phase: A brief and headlong ATTACK phase with immediate results. During this phase, the diet is made up of 72 high protein foods. This phase can last from 2 – 10 days depending on how much you have to lose and you only eat high protein foods, but can eat as much as you want.
Cruise Phase: A CRUISE phase leading to getting you down to your True Weight. During this phase, the diet alternates between Pure Protein days (PP phases) and Proteins accompanied with 28 recommended Vegetables (PV phases). So you do one day of Pure Protein and one day of Protein plus Vegetables.
Consolidation Phase: A CONSOLIDATION phase which prepares for the return to a balanced diet. The length of this phase depend on how much weight you have lost. In Consolidation you will gain more freedom in your food choices but will stabilize your new weight while learning how to maintain. This phase sees the gradual return of pleasurable foods with one celebration meal a week in the early part and two celebration meals a week in the later part.
Stabilization Phase: A definitive stabilization phase based on 3 simple, concrete, easy but non-negotiable measures. This phase is both the easiest and most essential in the Dukan Diet because 95% of people who follow a diet put back on the weight they have lost.
