The Dukan Diet is a structured, four-phase weight management program that progressively introduces a wider variety of foods. Success hinges on strictly adhering to the allowed food lists for each phase. Here is a comprehensive breakdown.
Phase 1: The Attack Phase
This initial phase is designed to kick-start weight loss rapidly and typically lasts between one and seven days, depending on the individual's weight loss goals. During this period, the diet is almost exclusively composed of pure proteins from a list of 68 approved items.
Allowed Attack Phase Foods
- Lean Meats: Lean beef (sirloin, tenderloin), veal, venison, bison, and lean pork cuts are permitted. Fatty cuts like ribs are prohibited.
- Poultry: All types of poultry except duck and goose are allowed, provided the skin is removed.
- Fish: Both fatty and lean fish are acceptable, including salmon, mackerel, cod, and tuna, prepared without added oil.
- Shellfish: Crab, shrimp, clams, lobster, and mussels are all on the approved list.
- Eggs: Chicken and quail eggs can be consumed freely.
- Vegetarian Proteins: Tofu, seitan, and tempeh are included for vegetarian options.
- Fat-Free Dairy: Skim milk, fat-free yogurt, fat-free cream cheese, and cottage cheese are allowed.
- Essential Additions: Daily intake of 1.5 tablespoons of oat bran is mandatory, along with ample water consumption.
Phase 2: The Cruise Phase
This phase alternates between protein-only days and protein-and-vegetable days until you reach your target weight. The duration depends on how much weight you need to lose.
Allowed Cruise Phase Foods
In addition to all the pure proteins from the Attack Phase, the Cruise Phase introduces 32 specific non-starchy vegetables.
Non-starchy Vegetables
- Leafy Greens: Spinach, lettuce, kale, and cabbage.
- Cruciferous Vegetables: Broccoli, cauliflower, and Brussels sprouts.
- Other Vegetables: Tomatoes, cucumbers, zucchini, bell peppers, asparagus, mushrooms, and onions.
Important Guidelines for the Cruise Phase
- Alternating Days: You must alternate between a "Pure Protein" day and a "Protein and Vegetable" day.
- Oat Bran: The daily oat bran intake increases to 2 tablespoons.
- Vegetable Preparation: Vegetables can be consumed raw, steamed, or baked, with minimal seasonings and no added oil.
Phase 3: The Consolidation Phase
The Consolidation Phase is crucial for preventing rebound weight gain and lasts five days for every pound lost. It gradually reintroduces a wider variety of foods.
Foods Added During Consolidation
- Unlimited Proteins and Vegetables: You can continue to eat all foods from the Cruise Phase.
- Daily Additions: One serving of fruit (excluding bananas, grapes, figs, and cherries), two slices of whole-grain bread, and 1.5 ounces of hard-rind cheese.
- Weekly Additions: One to two servings of starchy foods per week and one to two "celebration meals". Lamb, pork, and ham are also reintroduced in this phase.
- Protein Thursday: One day per week, you must revert to the pure protein diet of the Attack Phase.
Phase 4: The Stabilization Phase
This is the final, indefinite phase designed for lifelong weight maintenance. While most foods are now allowed in moderation, three non-negotiable rules must be followed for life.
Rules for the Stabilization Phase
- Daily Oat Bran: 3 tablespoons of oat bran per day.
- Protein Thursday: One pure protein day per week.
- Physical Activity: Prefer stairs over elevators and aim for a daily 20-minute walk.

Conclusion: Navigating the Dukan Diet Foods
Successfully following the Dukan Diet requires a clear understanding of what foods are allowed in each of its four phases. The diet's structure moves from a restrictive, protein-heavy start to a more flexible, balanced approach for long-term maintenance. By adhering to the specific food lists and rules for each stage, individuals can navigate the plan effectively. However, due to its restrictive nature, especially in the early phases, some health experts have raised concerns about nutritional deficiencies and long-term sustainability. Therefore, always consult with a healthcare professional or registered dietitian before starting any new diet.
