what is the keto diet

The keto (ketogenic) diet is a new trend in dietary nutrition. The keto diet started gaining the greatest popularity in 2017 and continues to this day.

The ketogenic diet is the newest version of the low-carb diet.

Keto Diet Principles

The main principle of the keto diet is low-carb foods. The ketogenic diet is based on processing the body's fatty acids. The breakdown of animal fats that enter the body with foods without the interference of carbohydrates is the key to a healthy diet with this method.

The low-carb keto diet is very popular among obese people, among people who want to lose weight or stay in shape.

With no minimum or no carbohydrates in the body, fat burning occurs rapidly, a person begins to lose weight. Fat begins to be excreted from the body and processed into fatty acids then becomes keto body.

Ketone bodies are fat-breaking products produced by the liver. With active energy expenditure or prolonged fasting, to obtain energy, the body begins to break down the fat it stores itself.

The breakdown of fat and the formation of ketone bodies is called ketogenesis and is a completely natural process for the human body. Ketogenesis does not lead to drastic weight loss.

Keto diet features

keto diet features

The hallmark of the keto diet is the substitution of the energy source provided - carbohydrates into fat, or rather decaying products - ketone bodies. In order to realign the body and based on individual characteristics, it is necessary to reduce the amount of carbohydrates consumed from 50 to 20 grams per day. It can take 2 to 4 weeks for the body to fully adapt to the new nutritional system. The peak form of fat burning is achieved by following a balanced diet.

The characteristics of the keto diet from all other types of diets are the limited amount of carbohydrates in the body, low protein content, and the presence of fat. The daily intake of carbohydrates in food should not exceed 20 grams per day. Ketones, a byproduct of animal fat that the body uses to produce energy, must have a fat to protein to carbohydrate ratio of 2 to 1. To maintain a normal metabolism, the body must accept large amounts of fat. 75% of the calories in your daily diet should come from fat, the rest being carbohydrates and protein. The product calorie intake per day should not exceed 5000 kcal. The diet does not limit the time to eat, you can eat safely after 18 hours.
