The Dukan Diet is a high-protein, low-carb eating plan created by French doctor Pierre Dukan. It gained international popularity when celebrities like Kate Middleton and Jennifer Lopez credited it for their weight loss. But what exactly is this diet? How does it work, and can it really help with long-term weight management? In this guide, we’ll explain the Dukan Diet in simple terms so you can decide if it’s right for you.

Chapter 1: The Basics of the Dukan Diet

The Dukan Diet is based on the idea that a protein-rich diet can help people lose weight without feeling hungry. Dr. Pierre Dukan introduced it in the 1970s, and it later became a bestseller worldwide.

The diet has four stages:

  1. Attack Phase
  2. Cruise Phase
  3. Consolidation Phase
  4. Stabilization Phase

Each phase has specific rules and goals. The diet starts with fast weight loss and gradually moves to long-term maintenance. The focus is on lean proteins, vegetables, and a few key rules like drinking lots of water and walking daily.

Chapter 2: The Four Phases Explained

1. Attack Phase

This phase jumpstarts your weight loss. It can last from 2 to 7 days, depending on how much weight you want to lose.

What you eat:

  • Lean meats (chicken, turkey, beef)
  • Fish and seafood
  • Eggs
  • Low-fat dairy (yogurt, cottage cheese)
  • Tofu and seitan (for vegetarians)
  • Oat bran (1.5 tablespoons daily)
  • Lots of water (at least 6-8 glasses a day)

No: Carbs, sugar, alcohol, or fats

You can expect to lose 4 to 6 pounds in this phase.

2. Cruise Phase

In this phase, you add non-starchy vegetables on alternate days.

Allowed veggies:

  • Leafy greens (spinach, lettuce)
  • Broccoli, cauliflower
  • Zucchini, cucumbers
  • Peppers, tomatoes
  • Mushrooms

You still eat all the protein from the Attack Phase, and you alternate between:

  • Pure protein days (PP)
  • Protein + vegetables days (PV)

This phase continues until you reach your goal weight. You may lose 1-2 pounds per week.

3. Consolidation Phase

Now, you maintain your weight and avoid regaining it. You slowly reintroduce healthy carbs and fats.

You can add:

  • 1 serving of fruit per day (except bananas, grapes, cherries)
  • 2 slices of whole grain bread
  • 1 serving of cheese
  • 2 celebration meals per week (anything you want, in moderation)
  • 1-2 servings of starchy foods (rice, pasta, potatoes) per week

This phase lasts 5 days for every pound you lost.

4. Stabilization Phase

This is the lifelong phase. You go back to normal eating with three key rules:

  • One pure protein day per week (like the Attack Phase)
  • 3 tablespoons of oat bran daily
  • 20 minutes of walking every day
