The model of this diet is the work of the French nutritionist, Dr. Pierre Dukan. In his book The Dukan Diet is mentioned that the diet program is designed to root into the brains of dieters.
The Dukan Diet consists of four programs that follow eating differently from each other. The program consists of a phase of "attack" pure protein, vegetable phase, consolidation phase and stabilization phase.
The most important element that links the four stages of the program is to eat protein alone for days. You only need to eat foods high in protein, low in calories, and reduce appetite. The body's absorption of the protein will lead to burning calories, and allow weight loss without losing muscle strength.
