The ketone diet was developed in 1921 to treat epilepsy. Later, bodybuilders began to use it to build muscle relief. The use of fats as fuel is possible only with a reduced amount of carbohydrates and a low percentage of protein - these are the principles of the keto diet.
Keto diet what is it?
The ketogenic, ketone or keto diet (keto) is a diet low in carbohydrates, moderate in protein and high in fat.
When carbohydrates are consumed, they lead to the formation of glucose and the production of insulin. Glucose is most easily consumed by the body as a fuel. Insulin is needed to deliver glucose to cells. In these cases, the fat remains unclaimed and only accumulates. But if carbohydrates are reduced, the body is forced to enter a state of ketosis - a natural process when the body begins to use fat as fuel.
In the liver, glucose deficiency forms ketone bodies of free fatty acids. Ketones or ketone bodies are molecules that carry energy for the body to function. The purpose of keto is to become such a state.
There are 4 types, 3 of which are used by athletes and one is used by all other keto supporters:
- Standard: basic keto - ratio in% BJU - 20: 75: 5.
- Purposeful: exercise increases the amount of carbohydrates during exercise.
- Cyclic: Higher carbohydrate intake, for example on weekends.
- High protein content: instead of decreasing, protein increases to about 35%. The total ratio of BJU becomes - 35: 60: 5.

The opinion of nutritionists about the keto diet
The focus of the keto diet is on protein and fatty foods, extremely low in fiber. This is fraught with bloating and heaviness in the stomach, constipation. In addition, the intestines are colonized by pathogenic microorganisms, which ends in dysbacteriosis. Immunity is reduced. To avoid such problems, fiber should be consumed at least to a minimum - cabbage, apples, grapes.
The big downside is the lack of carbohydrates, the body can react to this with an inadequate response.
If physical activity is higher than the body's capacity, it can provoke hypoglycemia in the form of weakness, drop in blood pressure, dizziness, nausea, fainting and collapse. To prevent it, it is better to use juices and semi-sweet fruits during snacks, and when the first signs of hypoglycemia appear, drink tea with honey.
Glucose deficiency reduces brain function. Cognitive components are especially affected - attention, concentration, memory. After reaching the ketosis phase, they will partially recover, but the level still does not reach the previous norm. Therefore, when taking exams, hard mental work it is better not to use this diet.
A ketogenic diet can lead to kidney stones, dehydration, elevated blood cholesterol levels, constipation and gout attacks. The main minerals and vitamins are deficient in keto, so it is necessary to take vitamin complexes.
Keto, of course, will improve the body and move the metabolism off the ground and lose weight, but the transition to such a special diet is quite difficult and requires consultation with a doctor. The keto diet is not for everyone. Only a doctor, after checking the current condition, can say whether it is allowed to start a diet.
