Keto diet

what is the keto diet

The keto diet (ketogenic) is a newfangled trend in dietary nutrition. The keto diet began to acquire 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 fats and the lowest carbohydrate content.

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

Principles of the Keto Diet

The main principle of the keto diet is low-carb foods. The ketogenic diet is based on the body's processing of fatty acids. The breakdown of animal fat entering the body with food with the non-interference of carbohydrates 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 in shape.

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

Ketone bodies are fat breakdown products that are produced by the liver. With the active expenditure of energy or prolonged fasting, to obtain 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.

Features of the keto diet

features of the keto diet

A feature of the keto diet is the substitution of the supplied energy resource - carbohydrates for fats, or rather decay products - ketone bodies. To reorganize the body and based on individual characteristics, it is necessary to reduce the amount of consumed carbohydrates 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.

A distinctive feature of the keto diet from other all kinds of diets is the limited amount of carbohydrates in the body, 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 to produce energy, must have a ratio of fat to protein and carbohydrates of 2 to 1. To maintain a normal metabolism, the body must receive large amounts of fat. 75% of the calories in your daily diet should come from fat, the rest is carbohydrates and proteins. The calorie 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 foods high in carbohydrates, the more effective the diet is in suppressing hunger.
The main part of the daily diet should be fat, followed by proteins and last but not least - carbohydrates. The peculiarity of this diet, unlike others, is that salt intake is not limited here, which restores the balance of electrolytes.

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

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

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