It’s bad if you are on a diet and don’t lose weight. And it’s worse if you lose the extra flab but gain it right back. If you want to lose weight and maintain it, follow the most effective diet plan created by Dr. Pierre Dukan – the Dukan Diet. Unlike other diet plans, it aids rapid weight loss, but you will not gain the weight back. And that’s because this diet plan is created by merging scientific evidence and Dr.Dukan’s experience on how the right nutrition can stimulate our body to lose weight. Sounds intriguing, right? Let’s find out more about this phenomenal diet plan and start losing weight today!

How The Dukan Diet Works

Dr. Pierre Dukan, who specializes in weight management, faced a challenge when one of his patients agreed to give up all foods except meat to lose weight. Dr. Dukan considered the patient’s love for meat and designed a high-protein, low-carb diet. He divided the diet into four phases – two weight loss phases and two weight maintaining phases. The high-protein, low-carb diet works by limiting the intake of carbs that readily convert into glucose. High glucose levels in the body lead to metabolic disorders, such as insulin resistance. When insulin is unable to take up glucose and convert it into usable energy, it gets stored in the body as fat. Proteins, on the other hand, take much longer to get digested and absorbed in the body. This keeps hunger pangs at bay and builds lean muscle mass. During the weight maintaining phase, you will be eating protein, complex carbs, healthy fats, and dietary fiber-rich foods. This balanced nutrition plan will help prevent the possibility of you gaining the weight back.

Now, let’s find out what should you eat during each phase of this diet plan.

The Dukan Diet Plan

Dukan Diet Attack Phase (Day 1 – Day 7)

During this phase, you will be on a high-protein, low-carb diet. You will follow this diet plan for 7 days.

MealsWhat To Eat
Early Morning (7:00 – 7:30 am)1 cup warm water
Breakfast (8:15 – 8:45 am)2 boiled eggs + ½ tablespoon oats bran
Mid-Morning (10:30 – 11:00 am)Green tea
Lunch (12:30 – 1:00 pm)Grilled salmon + 1 cup low-fat yogurt
Evening Snack (4:00 pm)1 cup lemonade (use artificial sweetener)
Dinner (7:00 – 7:30 pm)Chicken steak + ½ cup warm milk
 Why This Works

The Attack phase focusses only on high-protein foods. This helps limit the carb intake and aids rapid weight loss. Drinking a cup of warm water as soon as you get up will help to flush out toxins and support proper bowel movement. You can have a proteinaceous breakfast, lunch, and dinner. Oats bran is a good source of dietary fiber and complex carbs. Yes, you cannot totally avoid carbs, and complex carbs are the best when it comes to weight loss. Dietary fiber binds to fat molecules and prevents fat absorption. You are also allowed to consume low-fat dairy products that are a good source of calcium and good gut bacteria that help to strengthen your bones and improve digestion. Green tea has no calories and helps suppress your appetite. You can have lemonade for your evening snack, but make sure to use just a drop of artificial sweetener. A cup of warm milk before bed will help you sleep better.

Here is the list of foods you are allowed to consume during the Attack phase.

 Foods You Can Eat In The Attack Phase
  • Meat – Chicken breast, lean cuts of pork and beef, fish, crab, mussel, shrimp, lobster, ground turkey, veal, and chicken liver.
  • Dietary Fiber – ½ tablespoon oat bran daily.
  • Dairy Eggs, low-fat yogurt, low-fat milk, ricotta cheese, and cottage cheese.
  • Beverages Water, lemonade, and green tea.
  • Others Olive oil, diet gelatin, pickle, and artificial sweetener
Useful Tip

Vegetarians can substitute meat with Seitan, which is made from wheat gluten. Avoid Seitan if you are gluten sensitive.

You must also exercise to help mobilize the fat. Here’s an exercise plan for you.

  • Neck rotations – 1 set of 10 reps (clockwise and anticlockwise)

 How You Will Feel By The End Of The Attack Phase

After the 3rd day, your body will go into the fat melting mode, and this is where exercising will benefit you. You will burn the calories effectively and build lean muscle mass. But remember, this diet won’t work if you don’t follow all the phases. So, let’s jump right into the next phase – the Cruise phase.

The Consolidation phase is the transition phase from strict diet rules to a less stringent diet. It marks the beginning of the weight maintenance phase. During this phase, you will not only consume proteins and veggies but also reintroduce starchy veggies into your diet.

A cup of low-fat milk will keep your hunger pangs at bay and strengthen your bones. Green tea is loaded with antioxidants and helps suppress your appetite. Oat bran is rich in dietary fiber and prevents fat absorption. Honey has antibacterial properties, and cinnamon aids weight loss by controlling blood sugar levels. A serving of fruits every day is necessary during this phase as it will provide your body with vitamins, minerals, fiber, and complex carbs. Have a protein-rich dinner, but also have starchy veggies to help your body transition from the 2nd phase of this diet to the 3rd.

This is the last phase of this diet and can last indefinitely. You can eat any food but not in excess amounts. You need to stay focussed and committed so that you do not slip back to your old unhealthy eating habits and regain the weight. 

MealsWhat To Eat
Early Morning (7:00 – 7:30 am)1 cup water with 1 teaspoon apple cider vinegar or lime juice
Breakfast (8:15 – 8:45 am)2 soft-boiled eggs + 2 tablespoons oat bran + 1 cup low-fat milk or 1 cup fresh fruit juice
Mid-Morning (10:30 – 11:00 am)4 almonds + 1 cup green tea
Lunch (12:30 – 1:00 pm)Tuna or mushroom sandwich
Evening Snack (4:00 pm)1 serving of fruits – Orange, peach, apricot, musk melon
Dinner (7:00 – 7:30 pm)Pasta with shredded chicken and broccoli + 1 piece of dark chocolate
 Why This Works

This diet chart will help you eat select foods that will help maintain the weight loss. Apple cider vinegar aids weight loss, and so does green tea. Eggs, tuna, chicken, and mushrooms are good protein sources. Oat bran, veggies, and fruits are rich in dietary fiber and complex carbs. Your body also needs healthy fats to maintain cell integrity and reduce inflammation. Therefore, almonds and olive oil are highly recommended. A piece of dark chocolate or a small scoop of ice cream will keep you interested in this diet and curb your sugar cravings.

Foods You Can Eat In The Stabilization Phase

You can consume any food you want, but keep these points in mind.

  • Have one pure protein day every week.
  • 2 tablespoons oat bran
  • 1-2 servings of fruits
  • 1-2 servings of veggies
  • Healthy fats
  • Have a celebration day every two weeks.
