Optimal Nutrition Dr. Jan Kwaśniewski

Optimal Nutrition according to Dr. Jan Kwaśniewski, i.e. high-fat, low-carbohydrate.

Dr. Jan Kwaśniewski (1937 – 2019)

Jan Kwasniewski, MD, was born in 1937 in Poland. In 1961 he graduated from the Military Medical Academy (Wojskowa Akademia Medyczna in Lodz) with a specialization in physical medicine. In 1965 he began working at the Military Sanatorium in Ciechocinek, where he was employed for many years. Early in his career at the sanatorium, he was ordered (it was a military sanatorium) to become a dietitian and was put in charge of patients’ nutrition and diets. He took on the assignment seriously, he studied the subject thoroughly, and within a couple of years (in 1968), he developed the optimal diet, which was proven effective at treating many diseases, such as auto-immune disorders, cardiovascular diseases, diabetes, digestive system diseases, and obesity.

Since the late 1960s, thanks to Dr. Kwasniewski’s books, millions of people all over the world have followed his Optimal Nutrition.

Breakfast in Tanzania

Since 2017, I have been eating egg yolks for breakfast as one of the most optimal products.

I have been living in Tanzania for a large part of the year, since 2020. Here, too, I use optimal nutrition. During the transitional period, I had to find or learn to prepare products that were compatible with the principles of optimal nutrition. As for breakfast, almost daily 5 egg yolks (Swahili: kiini cha yai), butter from a cow (Swahili: siagi) and a few cloves of garlic (Swahili: vitunguu saumu).


This model of nutrition should be started immediately, without any transitional periods.

Butter (only from the cow), moderate amounts of vegetables. Carbohydrates only 0.8 g per kg of body weight.

1 g of protein per 1 kg of body weight, and once you switch to the most valuable animal protein for humans (e.g. domestic egg yolks, bone marrow, liver), the requirement drops to 0.5 g per 1 kg of body weight.

The base proportion of proteins (P), fats (F) and carbohydrates (C):

P : F : C
1 : 2,5÷3,5 : 0,5

Target base proportion of proteins (P), fats (F) and carbohydrates (C):

P : F : C
1 : 2,5÷3,5 : 1
