Ketogenic diet

what is the keto diet

The ketogenic (ketogenic) diet is a novel trend in dietary nutrition. The ketogenic diet began to grow in popularity in 2017 and continues to this day.

The ketogenic diet is an approach to a healthy lifestyle. Preference is given to natural food products according to the needs of the human body with the presence of fats and the lowest content of carbohydrates.

The ketogenic diet is an updated version of the low-carb diet.

Ketogenic Diet Principles

The main principle of the ketogenic diet is low carbohydrate foods. The ketogenic diet relies on the body's processing of fatty acids. The breakdown of animal fat that enters the body with food without carbohydrate interference is the key to a healthy diet with this method.

The low carb ketogenic diet is very popular with obese people who want to lose weight or stay in shape.

With a minimal or complete absence of carbohydrates in the body, the burning of fat occurs rapidly, a person begins to lose weight. Fats begin to be eliminated from the body and processed into fatty acids and then into the ketogenic body.

Ketone bodies are fat breakdown products produced by the liver. With active expenditure of energy or prolonged fasting, for energy, the body begins to break down 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 lead to drastic weight loss.

Characteristics of the ketogenic diet

Keto diet features

A characteristic of the ketogenic diet is the replacement of the supplied energy resource, carbohydrates by fats, or rather decomposition products, ketone bodies. To reorganize the body and depending 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 maximum form of fat burning is achieved by following a balanced diet.

A distinctive feature of the ketogenic diet from other types of diets is the limited amount of carbohydrates in the body, the low protein content, and the presence of fats. The daily intake of carbohydrates in food should not exceed 20 grams per day. Ketones, the by-products of animal fats that the body uses for energy, must have a 2-to-1 ratio of fat to protein and carbohydrates. To maintain normal metabolism, the body must receive large amounts of fat. 75% of the calories in your daily diet should come from fat, the rest are carbohydrates and proteins. The caloric intake of products per day should not exceed 5000 kcal. The diet does not limit the time of eating, you can safely eat after 18 hours.

The less a person consumes carbohydrate-rich foods, the more effective the diet is in suppressing hunger.
The main part of the daily diet should be fat, followed by protein, and last but not least carbohydrates. The peculiarity of this diet, unlike others, is that the salt intake is not limited here, which restores the electrolyte balance.

In the first days of the diet, you should gradually reduce the amount of carbohydrates consumed.

With the strict principle of adherence to the ketogenic diet for weight loss, a person can easily lose 3 to 5 kilograms of weight in a month without damaging their health and reducing the amount of adipose tissue.

Athletes are more likely to stick to a cyclical ketogenic diet, burn fat, their bodies become more prominent, and increase muscle mass. The reason for this change lies in the transformation of the hormonal background and the increase in the process of formation of growth hormone. The principle of the diet is strictly regulated with the training plan.
