The Dukan Diet is a weight-loss program, developed by French nutritionist Pierre Dukan, that uses four distinct diet phases to allow dieters to achieve weight stabilization and reach their goals. The diet focuses its early phases on high-protein, low-carbohydrate food choices. In later stages, dieters learn how to reintegrate healthy carbohydrates into meals while practicing long-term weight-management skills, such as calorie control and exercise.

The “cruise” phase of the Dukan Diet is the second phase of the program; it begins between day two and day 10, depending on the individual dieter’s weight-loss goals. The cruise phase focuses on high-protein, low-carbohydrate food choices and allows alternating days of protein-only menus and with those that protein and vegetables.
Protein days in the cruise phase are limited to meat, fish, eggs and fat-free dairy products. Options include chicken, turkey, low-fat red meats, low-fat ham, fish, such as tilapia, crustaceans and shellfish. Allowed dairy products include fat-free cottage cheese, skim milk and flavored or plain yogurt with no added fruits. The plan allows two eggs per day. Three or four eggs each week can contain the yolks; the rest should be served only as the egg whites.
Vegetable and Protein Days
On protein-and-vegetable days, the protein options are accompanied by sides or salads made from a variety of vegetables; options include spinach, broccoli, cabbage, asparagus, kale, chard, eggplant, cucumber, tomatoes, beans, pepper, turnips and leeks. Carrots and beets are allowed but should be not be eaten at every meal because of their higher starch contents. The cruise phase allows dieters to eat vegetables in the amount that satisfies their hunger; there are no set portions.
The cruise phase of the Dukan Diet recommends that the dieter consume a minimum of 1.5 L of water per day. A Dukan Diet follower can also consume 2 g of oat bran daily to prevent constipation. The diet plan suggests that participants exercise a minimum of 30 minutes a day by engaging in brisk walking or light jogging. Physical activity plays a key role in encouraging weight loss, improving muscle tone and enhancing cardiovascular fitness.
