Pierre Dukan, MD, a French doctor who specializes in weight loss and management, created the Dukan diet in the 1970s after being inspired by a patient with obesity. The man told Dr. Dukan he could give up anything if it would help him lose weight — except for meat.
The “true weight” calculation considers your sex, age, weight loss history, and a variety of other factors. This number will then be your goal.
The Dukan diet contains four phases designed to help you meet your goal weight. The length of time each phase lasts depends on your “true weight.”
The Attack Phase
The first phase kicks the diet off with a heavy amount of lean protein. It can last from one to seven days, depending on how much weight you need to lose.
The Cruise Phase
In the second phase, you can start adding nonstarchy vegetables to your eating plan. You’ll alternate between one day of only lean protein and one day of lean protein mixed with nonstarchy vegetables, plus you’ll increase to a 2-tbsp serving of oat bran per day.
The Consolidation Phase
After the first two phases have helped you lose weight, the Consolidation phase gradually introduces more food groups. This phase lasts five days for every pound lost and aims to prevent rebound weight gain.
The Stabilization Phase
The final phase lasts indefinitely and is meant to help you keep the weight off. It’s very similar to the Consolidation phase, but allows you to be a little looser with the carbs and fats.
