Dukan Diet – How It Helps In Weight Loss, Phases, And Diet Plan

The Dukan diet provides high protein and low carb for weight loss that is divided into four phases. This diet was introduced by Dr. Pierre Dukan, a general practitioner from France, who specialized in weight management.

Dr. Dukan created a diet in the 1970s, inspired by an obese patient who said to give up eating to lose weight, except for meat.

After seeing different patients’ experiences, and impressive weight loss results from this diet, Dr. Dukan issued The Dukan-Diet in 2000.

The book was eventually issued in 32 countries and became a major bestseller. It reportedly helped people to get easy and rapid weight loss without hunger.

The duration of this period will be based on the quantity of weight you lose. For every kg lost, you have to maintain it for 10-days. Therefore, if you have already lost 6kg in the previous 2-phases, you will need to continue this phase for 2-months. During this 3rd phase, you will get 6-days of vegetables containing protein a day and 1-day of Pure-Protein day a week.

More foods are included back to diet but in a controlled manner. Besides the 100 approved Dukan foods, you can immediately eat these foods in the diet throughout the 6-protein vegetable days:

Is the Dukan Diet based on evidence?

Dukan Diet - How It Helps In Weight Loss, Phases, And Diet Plan 18

There is no more quality research about the Dukan diet. However, one research in Polish women who followed this Dukan Diet shown that they are about 1,000 calories and 100 gm of protein every day while reducing 33 pounds than 15 kg in 8-10 weeks.

Additionally, different research shows that other low-carb diets and high protein diets provide more benefits for weight loss.


Different factors contribute to getting the beneficial effects of protein for weight. One of these is to increase calorie burning while gluconeogenesis, which is a process in which fat and protein are changed into glucose when carbs are limited and protein consumption is high. The metabolic rate of the body also raises significantly high after you eat protein than after you consume fat or carbs, making you satisfied and full.

Additionally, protein lowers the hunger hormone ghrelin and raises different fullness hormones. Therefore, you end up consuming low.

However, the Dukan Diet is different from different linked high protein diets in that it limits both carbs and fat. It is a low carb, high protein, and low-fat diet.

The rationale for limiting fat on a low carb and high protein diet is not based on science.

According to one study, people eating fat with more protein, and low carb meals burned around 69 more calories than those who skipped fat also.

Is initial stages of this diet also have low fiber, even though an everyday serving of oat bran is necessary.

The servings of 1.5-2 tablespoons that is 9-12 grams of oat bran consist lower than 5 grams of fiber, which is the little amount that does not offer different health benefits of a high fiber diet.

Additionally, different healthy sources like fiber, such as nuts, avocados are not added to the diet because they are considered more fat.



Is It Sustainable and Maintained?

The safety of the Dukan diet has not been researched. However, concerns about high protein consumption, especially its effect on bone health In the past, it was thought that high protein could cause kidney damage. However, newer research has discovered that high protein diets are not risky to people with healthy kidneys.

It is seen that people with kidney stones could get worse conditions with high protein consumption. Bone health will not get affected with a high protein diet, as long as you eat high potassium vegetables and fruit.

Recent research recommends that high protein has helpful for bone health. People with kidney problems, liver disease, and other serious health should talk with a physician before starting a high protein diet. Remember that the diet’s restrictive and complicated nature may consume it difficult to follow. Although most people will lower in the first 2-phase, the diet is quite reducing specifically on the pure protein days. The diet also limits high-fat foods, which are good for health. Adding plant fat and animal fat makes a low-carb diet healthier, more enjoyable, and easy to follow for more time.

Does It Work?

Dukan Diet - How It Helps In Weight Loss, Phases, And Diet Plan 21

The first stage of the Dukan Diet will likely lead to significant weight loss because of some carbohydrates on the plan. But when you get back to normally consuming after reaching weight gaol, you may get some weight back.

Research shows that high protein diets are very effective for weight loss. But experts still do not find what the effect of the long term is for weight and health.

There is no evidence that all protein consumption in one day with a workout is enough to manage weight loss.


Is It Good for Specific Conditions?

Although the diet can induce weight loss, which can benefit some health conditions, the chances may outweigh its benefits.

If you are taking diabetes medication, you will likely require to change the dose, because the first two-stage are less in carbohydrates. If you are suffering from renal disease, you might get extra protein that your kidneys can manage. If you are suffering from heart disease or a digestive problem, you would be missing out on fiber that is healthy for the heart. Because of the restrictive nature of this plan, it is essential to have physician advice.


The Final Word

Unlike other diets with high protein, this plan target on lean protein source on those high in saturated fat. Protein can keep you feel fuller and help in weight loss.

The downside is about this plan does not make you learn healthy eating habits. Even more problematic, it is suggested that you stay in the consolidation phase till you get the goal. If you lose more weight, this phase could go on for one month or more years, which could cause a nutritionally enough diet.
