Kwaśniewski’s high-fat diet – a compendium of knowledge

dieta Kwaśniewskiego - przepisy

The number of nutrition programs that are designed to help us lose weight is extremely large. There are more and more diets that focus on predetermined products because of their health properties. However, some of these diets are considered controversial. One of such diets seems to be the diet of a Polish doctor, Jan Kwaśniewski. Why is Kwaśniewski’s high-fat diet so popular?

In the article, we will discuss the most important issues regarding the diet – we will describe exactly what it is, what are its properties and in what situations it will help. In addition to the specifications, we will also discuss what Kwasniewski’s diet helps with, what are its disadvantages and what are its advantages.

What is the Kwasniewski diet?

The Kwaśniewski diet is a specially designed nutritional program based on two principles. The first rule is to limit carbohydrates in the diet to a minimum. The second rule is to focus on eating foods that are rich in fat. This means that the Kwasniewski diet, like the Atkins diet, is a high-fat diet. According to Kwasniewski, the amount of energy that will come from carbohydrates should be a maximum of 15% of the daily requirement. For proteins, it should be 20-30% of the total daily requirement. 

It is also worth pointing out that Kwaśniewski’s diet is mistakenly called the optimal diet. In an optimal diet, the body receives all the nutrients and energy that are necessary for the proper functioning of the body. This means that the optimal diet is a complete diet. For this reason, we often recommend an optimal diet for beginners who do not yet know how to eat in order not to deteriorate their condition.

Kwasniewski’s diet for what it helps

The described diet was developed mainly for people suffering from overweight or obesity. It is therefore a slimming diet whose task is to lose extra pounds. Remember, however, that this diet, in terms of weight loss, has little effect on people with a normal body weight.

What else does the Kwasniewski diet help with? In addition to the main properties of the diet, it was also found that the nutritional program improves mood. In addition, high-fat diets – such as those proposed by Kwasniewski or Atkins – may affect the frequency of epilepsy symptoms in children.

What is the difference between the Kwasniewski diet and the Atkins diet?

It is true that both diets presuppose a similar way of eating. In both cases, therefore, we limit carbohydrates to a minimum, and the main source of energy is energy that comes from fats. However, there is a major difference between the Kwasniewski diet and the Atkins diet. It is the amount of protein in the diet.

Kwasniewski’s diet, in addition to a very reduced amount of carbohydrates, also assumes little protein. This means that the daily protein requirement in the case of Kwasniewski’s diet is about 60-90 grams. This is, of course, assumed 20-30% of the total demand.

For the Atkins diet, the numbers are different. Protein plays a bigger role in nutrition according to the American doctor. Therefore, you should consume from 115 to even 175 grams of protein every day. This means that high-protein foods are more important to the American high-fat diet.

Kwasniewski’s diet pros and cons

What are the positive and negative aspects of following the Kwasniewski diet? Certainly, it should be remembered that this diet is effective only in the case of slimming people who are overweight or obese. However, what exactly are the benefits of this nutritional program?


  • Fast weight loss

If our body mass index (so-called BMI) exceeds the norm, the Kwaśniewski diet is a very good solution. It will definitely speed up the process of losing unnecessary kilograms. During the nutritional program, it is possible to get rid of 5 kilograms of body weight, most of which is fat tissue and water deposited in the body.

  • Mood improvement

Ketone bodies are substances that are formed during the breakdown of fats. They are responsible for the state of euphoria and improved mood. Thanks to a fat-based diet, the amount of ketone bodies formed in the body is large, and thus our well-being is excellent, we are happier and we feel lighter.

  • The frequency of epilepsy in children

Ketone bodies, which are formed after the breakdown of fats, have a positive effect on the incidence of epilepsy in children, especially in cases where children are resistant to medications. In addition, there are reasons to believe that fat diets, including the Kwaśniewski diet, should also be used in the case of other diseases, including Rett syndrome, Dravet syndrome, and tuberous sclerosis.


  • No macronutrient balance

Lack of carbohydrates and low amount of protein means deficiencies of vitamins and minerals in our body. This can lead to deterioration of health and weakness, especially if we do not decide to supplement the missing ingredients.

  • The feeling of euphoria passes quickly

The mood improvement caused by ketone bodies usually wears off after two or three months. Then we feel lethargic, tired, we do not feel like doing anything. For this reason, the Kwasniewski diet, like the Atkins diet and other diets based on similar principles, should be used for a short period of time.

  • Exposure of the body to the appearance of disease syndromes

A fat-based diet carries the risk of eating foods that can raise our cholesterol levels. Elevated cholesterol and triglycerides in the blood serum are responsible for a higher risk of type 2 diabetes and atherosclerosis.

Kwasniewski’s diet – opinions

However, what are the opinions on Kwaśniewski’s diet on the Internet and where is the best place to look for them? We should certainly avoid blogs from people we’ve never heard of before. Such sources can quite often be sponsored, and thus present either the positives or the negatives of a given diet.

However, we encourage you to register on specialist forums and forums related to overweight and obesity – this is where you can often find advice and information about diets and supplements that support the slimming process. From such places we will learn that Kwaśniewski’s diet can actually help. However, many people confirm that this is only a temporary diet and should not be used long-term.

Opinions about Kwaśniewski’s diet also indicate that the diet actually has negligible effects on people with a normal body weight. Therefore, it is a very good solution only for people who, being overweight and obese, are tired of losing weight.

Kwasniewski’s diet – what to eat

Before you decide on a specific diet, it is also worth discussing the issue of the menu. So what recipes can we find in Kwaśniewski’s diet?

An example of a breakfast that meets the principles of the Kwaśniewski diet will be scrambled eggs with bacon. Taking into account the fact that Kwaśniewski’s diet may contain carbohydrates, we recommend adding a small amount of potatoes to dinner – this way chicken breast or pork chop poured with frying fat will be more satiating. An alternative to such a dinner can also be liver with garlic.
