Translated from Polish by the Czech creator of the best Optimal Diet website:
"Jan Kwasniewski was born in 1937 in Poland. He graduated from the Military Medical Academy and specialised in Physical Medicine.For many years he worked in the Military Sanatorium in Ciechocinek as dietician where he introduce famous in Poland and at present all over the world his nutritional method which gives the humans good and long health. This method was named "Optimal Diet" which is the cornerstone to the nutritional theory. The principles of the optimal diet at first shock people because the diet recommends eating large quantities of fats along with a radical cut of carbohydrates. The basic premise is that the dieter should keep the proper proportion among the three fundamental nutrients in food: protein, fat and carbohydrates. He found that the ideal proportion is from 1:2.5:0.5 to 1:3.5:0.5 meaning that with every gram of protein 2.5 to 3.5 grams of fat and half a gram of carbohydrates should be eaten. In another words, optimal nutrition is a high fat, low carbohydrate diet."
