The keto diet

what is keto diet

The keto (ketogenic) diet is a new trend in food nutrition. The keto diet began to gain the greatest popularity in 2017 and continues to this day.

The keto diet is an approach to a healthy lifestyle. Preference is given to natural food products in accordance with the needs of the human body with the presence of fat and low carbohydrate content.

The ketogenic diet is the latest version of a low-carb diet.

Principles of Keto Diet

The main principle of the keto diet is low-carb foods. The ketogenic diet is based on the processing of body fatty acids. The breakdown of animal fats that enter the body with carbohydrate-free foods is the key to a healthy diet with this method.

The low-carb keto diet is very popular with obesity, among people who want to lose weight or stay healthy.

With a minimum or complete absence of carbohydrates in the body, fat burning occurs quickly, a person begins to lose weight. Fat is first removed from the body and processed into fatty acids and then into the keto body.

The ketone body is a fat-breaking product produced by the liver. With active energy expenditure or prolonged fasting, in order to gain energy, the body begins to decompose its own stored fat.

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 cause drastic weight loss.

Keto diet features

keto diet features

The characteristic of the keto diet is the replacement of the energy source supplied - carbohydrates for fat, or more precisely the decomposition product - the ketone body. To reorganize 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 will 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 specialty of keto diets from all other diet types is the limited amount of carbohydrates in the body, low protein content and the presence of fat. Daily carbohydrate intake should not exceed 20 grams per day. Ketones, the by-products of animal fats that the body uses to produce energy, must have a fat to protein and carbohydrate ratio of 2 to 1. To maintain a normal metabolism, the body needs to get a lot of fat. 75% of the calories in your daily diet should come from fat, the rest is carbohydrates and protein. The daily caloric intake of the product should not exceed 5000 kcal. Diet does not limit meal time, you can eat safely after 18 hours.

The less a person eats foods high in carbohydrates, the more effective the diet in suppressing hunger.
The main part of the daily diet must be fat, followed by protein and last but not least - carbohydrates. The special feature of this diet, unlike any other, is the unlimited salt intake here, which restores electrolyte balance.

At the beginning of the diet, you should gradually reduce the amount of carbohydrates consumed.

The reason for these changes lies in the transformation of the hormonal background and the increased process of growth hormone formation. Dietary principles are strictly regulated by exercise plans.
