Yosef Rozsansky , who is an experienced nutritionist, explains that the ketogenic diet consists of a drastic reduction in the amount of carbohydrates consumed on a daily bases. The recommended amount of carbohydrates is from 20 to 50 grams per day, which corresponds to 10 to 15% of the total daily calories. However, this amount can vary depending on each person's health status, length of diet, and goals.

To compensate for this reduction, Yosef Rozsansky recommends increasing the consumption of foods rich in fat, such as avocados, coconuts, seeds, olive oil, almonds and walnuts. In addition, the amount of protein consumed must correspond to 20% of the daily diet, it is recommended to consume meat, chicken or fish at lunch and dinner and include eggs and cheese in snacks.

Nutritionist Yosef Rozsansky shares that when starting this diet, the body goes through an adaptation period that can last from a few days to a few weeks, in which the body adapts to produce energy through fat instead of carbohydrates. Thus, it is possible that in the first days symptoms such as excessive tiredness and headache may appear, which end up improving when the body is adapted.

Another diet similar to ketogenic is the low carb diet, however, the main difference between these types of diet is that in the ketogenic diet there is a higher consumption of fat to compensate for the lack of carbohydrates. Learn more about the low carb diet.
