what is a keto diet

The keto diet (ketogenic) is a new nutritional trend. The keto diet began to gain its most popularity in 2017 and continues to this day.

The keto diet is an approach to a healthy lifestyle. Preference is given to natural foods according to the needs of the human body with the presence of fat and the lowest carbohydrate content.

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

Keto Diet Principles

The main principle of a keto diet is low carb foods. A ketogenic diet is based on the processing of body fatty acids. The distribution of animal fat in the body with food without disturbing carbohydrates is the key to a healthy diet with this method.

A low carb keto diet is very popular with obesity among people who want to lose weight or stay in shape.

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

Ketone bodies are fat breakdown products produced by the liver. With active energy consumption or prolonged fasting for energy, the body begins to break down its accumulated fat.

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

Peculiarities of the keto diet

keto diet features

A feature of the keto diet is the replacement of the supplied energy resources - carbohydrates - fats or rather decomposition 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 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 keto diet from other diets of all types is its limited carbohydrate content, low protein content, and presence of fat. The daily intake of carbohydrates in food should not exceed 20 grams per day. For animal fat by-products, which are used by the body to produce energy, ketones should have a fat to protein to carbohydrate ratio of 2 to 1. The body needs a large amount of fat to maintain a normal metabolism. 75% of the calories in your daily diet should be from fat, the rest is carbohydrates and protein. The daily caloric intake of the products must not exceed 5000 kcal. Diet does not limit eating time, you can safely eat after 18 hours.

The less a person consumes high-carbohydrate foods, the more effectively the diet suppresses hunger.
The main part of the daily diet should be fat, then protein and finally carbohydrates. The peculiarity of this diet, unlike others, is that the intake of salt here is not limited, which restores the electrolyte balance.

Carbohydrate intake should be gradually reduced during the initial diet.

By following a strict 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 follow a cyclic ketogenic diet, burning fat, making their bodies more visible and gaining muscle mass. The reason for these changes is the transformation of the hormonal background and the increasing process of growth hormone formation. The principle of nutrition is strictly regulated by the training plan.
