Keto diet

what is the keto diet

The ketogenic (ketogenic) diet is an innovative trend in dietary nutrition. The ketone diet started to gain greater popularity in 2017 and continues today.

The ketone 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 lower carbohydrate content.

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

Principles of the Keto Diet

The main principle of the ketone diet is low-carbohydrate foods. The ketogenic diet is based on the processing of fatty acids by the body. The breakdown of animal fat that enters the body with food, without the 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 get in shape.

With a minimal or complete absence of carbohydrates in the body, fat burning occurs quickly and the person begins to lose weight. Fats start to be removed from the body and processed into fatty acids and then into the ketone body.

Ketone bodies are products of the breakdown of fat produced by the liver. With active energy expenditure 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 totally natural process for the human body. Ketogenesis does not lead to drastic weight loss.

Characteristics of the ketone diet

characteristics of the keto diet

A characteristic of the ketone diet is the substitution of the energy resource provided - carbohydrates for fats, or rather, decomposing products - ketone bodies. 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 the body 2 to 4 weeks to fully adapt to the new nutritional system. Peak fat burning is achieved by following a balanced diet.

A distinctive feature of the ketone diet in relation to all types 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 the diet should not exceed 20 grams per day. Ketones, by-products of animal fats that the body uses to produce energy, must have a 2 to 1 ratio of fat to protein and carbohydrates. To maintain a normal metabolism, the body must receive large amounts of fat. 75% of the calories in your daily diet must come from fat, the rest are carbohydrates and proteins. The caloric intake of products per day should not exceed 5, 000 kcal. The diet does not limit the feeding time, you can safely eat after 18 hours.

The less a person consumes foods rich in carbohydrates, 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 salt intake is not limited here, which restores electrolyte balance.

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

With the strict principle of adherence to the ketone diet for weight loss, a person can easily lose 3 to 5 kg of weight in one month without harming their health and reducing the amount of fat tissue.

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