This high-protein type diet was created by French nutritionist and eating behaviour specialist Dr Pierre Dukan.
How it works
Similar to a high protein diet, the Dunkan Diet has a 4-phase programme. It's high in protein, low in calories and also reduces your appetite. What’s more, the body’s absorption of protein leads to high calorie expenditure and allows weight loss without loss of muscle strength.
The programme also takes the post-diet period into account and helps you avoid putting weight back on when you return to a normal eating pattern.
The phases
- Pure protein attack phase: you only eat protein, i.e. meat, poultry, fish, seafood and fat-free dairy products. This phase lasts for 3 to 10 days depending on your target.
- Cruise phase: like the attack phase, only vegetables are gradually added to the protein. All that's off the menu are starchy foods (potatoes, sweetcorn, peas, lentils, green beans etc).
Then you alternate these 2 phases until you reach your desired weight (maximum loss 1kg per week).
- Consolidation phase: you return to normal eating as slowly as possible to avoid the dreaded yo-yo effect, reintroducing forbidden foods gradually. Allow for 10 days of consolidation for each kilo lost.
- Stabilisation phase: you eat normally, respecting two golden rules: have a pure-protein day once a week for life, and eat 3 tablespoons of oats and bran per day.
