The keto diet was created to treat patients with diabetes, but some doctors have decided to try it for weight loss. “RBC Style” understands who is suitable for and why a ketogenic diet can be dangerous, how to choose products, and make a menu.
The keto diet, or ketogenic diet, is a low-carb, high-fat diet. The keto diet helps lower blood sugar levels, increase insulin sensitivity, improve well-being, and lose weight by altering your metabolism.
The change in diet induces a state of ketosis, a metabolic regime in which the body obtains fuel from animal foods. The main energy source is ketone bodies: acetone, acetoacetate, and beta-hydroxybutyric acid.
These are substances formed in the liver from fatty tissues of the body and consumed fats. Ketone bodies feed the internal organs, muscle tissue, and brain instead of glucose.
The process of ketosis can be started with the help of fasting, but the keto diet allows you to enter this state and stick to it constantly without any health risks.
Ketosis is a natural metabolic state of the body in which fats and fatty tissues become the main energy source instead of glucose.
The keto diet is a diet that is high in fat and low in carbohydrates. The body gets energy from animal foods instead of glucose. Such a diet can help lower blood sugar and insulin levels and help lose weight.
The Keto diet cannot be called carbohydrate-free: their daily amount is 5% of the diet or 20-50 g of the product.
But to start and maintain a state of ketosis, you need to remove or reduce the amount of high-carb foods from the menu:

No diet by itself provides long-term weight loss and can be harmful to health. After a temporary weight loss, people return to their previous state and sometimes recover more than before the change in diet. A safe and effective way to achieve your desired weight and maintain your health and fitness is with the help of experts to find the right lifestyle and diet you can follow all the time.
Experts confirm that the keto diet is 2.2 times more effective for weight loss than a low-fat diet, weight loss is due to:
In 2018, Polish professor Maciej Banach presented a report on the dangers of low-carbohydrate diets at the European Society of Cardiology congress. Studies have shown that in a control group of 24,000 participants, the risk of dying from heart disease, stroke, and cancer was 50%, 51%, and 35% higher among those who followed a high-fat, low-carbohydrate diet.
In January 2020, the International Committee of Physicians recommended that low-carbohydrate diets, including the keto diet, be removed from the dietary guidelines for Americans. Doctors have indicated that such a diet increases the risk of heart disease.
In addition, being in ketosis has side effects to be aware of.
The general deterioration occurs with a change in diet and lasts several days
Symptoms:
It is necessary to strictly follow the diet in the first weeks to accustom the body to the new regimen. With symptoms of keto-flu, it is important to eat your fill and drink at least 2 liters of fluid daily, preferably containing electrolytes. Experts recommend adding MCT oils (fatty acids derived from coconut and palm oil), minerals (salt, soda, magnesium), caffeine, creatine, whey protein, and fiber foods to your diet. In addition, you need to reduce physical activity.
Ketosis is a natural physiological regime in which the body produces the number of ketone bodies that the body needs. Ketoacidosis is a pathological condition when the level of glucose and ketone bodies is excessive, leading to coma and death. The cause of ketoacidosis may be diabetes, prolonged fasting, or a reaction to an increase in fat in the diet.
Risk group: people with type I and II diabetes, children aged 1-13 years, nursing mothers.
According to studies, a ketogenic diet can provoke the formation of kidney stones in 6.7% of patients.
To date, this nutrition strategy has not been recognized by any of the world’s healthy communities and cannot be recommended by official medicine.
With this type of nutrition, more than 80% of the energy content of the diet is provided by fats, while carbohydrate intake is limited to 20 g per day or up to 50 g, which is more sparing and somewhat better tolerated. In fact, most often, the keto diet is low-carb (and the transition to ketosis is associated with this) and often high-protein. With this diet, saturated fats, including trans fats, and protein, predominate in the body.
It often happens that most followers of the keto diet at the initial stage do not have a clear understanding of what foods are acceptable on a ketogenic diet, but it is more or less clear what should be avoided. Therefore, meat products are used, which has its consequences.
This can provoke a deficiency of dietary fiber found in carbohydrate foods, and a deficiency of water-soluble vitamins, such as vitamin C, and minerals, is possible. Such food can hardly be considered safe. And it is extremely difficult to stick to it all your life, and only this option allows you to ensure a stable weight if we talk about losing weight.
