The Dukan Diet is one of the most commonly advertised weight loss methods. Understanding how the diet works, what is the "right" weight gain and why eating can be dangerous, according to Dukan.

Who is Pierre Ducana

The creator of the popular diet is not a nutritionist, but a physician. Pierre Ducan was in general practice when an obese patient visited him in 1970. The man admitted that he was willing to give up any food other than meat in order to lose weight. The doctor developed a diet based on a minimum amount of lean meat, non-starchy vegetables and fruits. A prerequisite was the refusal of sugar.

Dukan argued that such a diet is best for natural metabolism: primitive humans ate meat, seasonal vegetables and fruits. Sugar was inaccessible to us in our understanding and should therefore now be abandoned.

After 30 years of experimentation and observation, Pierre Dukan released the book I Can't Lose Weight, which became a bestseller in 32 countries. The new method allowed 5 kg of weight gain in one to two weeks, without limiting itself in food intake. promised to reduce.

Celebrities who openly praised the new method added popularity to Dukan's designs. Jennifer Lopez and Gisele Bundchen used the diet to lose weight during pregnancy and after childbirth. Welsh singer Katherine Jenkins has claimed that sheDucan is sized according to plan.

In 2012, the French Council of Physicians indicated that nutritionists violated ethical principles by making the drug a commercial enterprise. In 2014, Pierre Ducan was expelled from the register of doctors for advertising and promoting the method.

how the diet works

The Dukan diet refers to a protein diet with a minimum of carbohydrates and fats. The plan includes 100 products that can be eaten in any quantity in the first weeks.

The method largely mirrors ketogenic diets and other low-carb meal plans, where the body is rebuilding itself to obtain energy from fat and protein. The diet's high protein content helps balance insulin production. and decreases production of the hunger hormone ghrelin. We become satiated more quickly and we eat less. However, the Dukan diet restricts not only carbohydrates but also fats. The safety and benefits of this approach are not supported by research. .

Before proceeding to the Dukan meal plan, you need to calculate your "correct" weight. This can be done using a special calculator. Calculation data on height, maximum and minimum weight, age, structural features of the bodyThe calculator was developed by Pierre Ducan, so the result should be scientifically verified and consult with your doctor.

The Ducan diet is divided into four phases:

  • attack.
  • repatriation.
  • Anchoring.
  • stabilization.

Noticeable weight loss begins already in the attack phase, which prompts you to continue eating according to the Dukan method. The reason for rapid weight loss is dehydration, as the body lacks fluids from carbohydrates. However, experts do not confirm the long-term effectiveness of the method and the health benefits of the diet. Let's find out how the diet works and why it has many contraindications.

The first two phases are aimed at losing weight, and the last are aimed at strengthening achievements. During the attack, only high-protein foods are allowed. Then add non-starchy vegetables, limit fats and extra carbohydrates.

Attack duration, reversion and reinforcement depend on how many kilos you need to lose to achieve the "right" weight. The final phase, which must be followed consistently, is the fixing phase in an attack pattern andCombines the diet of weekly protein days.

There are many scientific publications that focus on the efficacy of high-protein, low-carbohydrate diets. However, there are few worthy studies according to the Dukan method.

In 2015, data were compiled of 50 women aged 19-64 in Poland who followed the Dukan meal plan and consumed about 1, 000 calories per day, including 100 grams of protein. Study participantsLost 15 kg in 8-10 weeks.

In January U. s. News & World Report, one of the top three US weekly on economics, politics and health, has published a diet ranking of 23 experts. Dukan's Diet ranked last on the list, receiving a score of 1. 9 out of 5. Expertsthe efficacy of the diet. 5 and health benefits rated at 2. According to doctors, there is no evidence that losing weight according to the Dukan method can be long-term and safe, while the list of products is unreasonably limited, and the diet regimen is too complex.

Scientists estimate that abstaining from this diet could lead to health problems in the future. And because the diet is limited, most people eventually stop eating according to the plan—they follow the 100 Foods List and the Rules of Their Rotation. become bored and uncomfortable.

doctor's comment

"The Dukan Diet is one of the most well-known ways to lose weight. And this diet has been tried in due course by most of the patients who come to me for consultations.

A reasonable question arises: why, then, do they need the professional help of a nutritionist-nutritionist? The answer is simple: Most of those who lose weight return to their previous eating habits, which means, within a few years, to their original weight. Unfortunately, this is the flip side of most diets that people resort to in their pursuit of leanness. And the Dukan Diet is no exception.

But this is not the most important argument because of which I would not recommend resorting to this diet.

The main disadvantage of this type of nutrition is the lack of essential macro- and micronutrients for a long time. The deficiency of vitamins and minerals can be compensated by special biologically active complexes, but this is due to the natural intake of natural macro- and microelements. This deficiency condition leads to a decrease in immunity, a deterioration in the work of all organs and systems of the body.

Dukan's diet increases the load on the excretory system, the liver, so it is clearly recommended for people with chronic renal and hepatic insufficiency, for pregnant and lactating women, people with impaired protein metabolism, gout, urolithiasis and cholelithiasis. Contraindicated from. And also during exacerbations of chronic diseases - gastritis, ulcers, pancreatitis, cholecystitis, pyelonephritis.

The Ducan diet is a serious stress for the body, the potential harm from it far outweighs the benefit, and the result is very unstable in the long term.

Follow the principles of optimal nutrition, get enough physical activity, and monitor your sleep and drinking regime. It won't take long to get the results you want and you'll be in good health. "
