Diet or keto diet, is a diet often used to lose weight and treat some diseases. It is a high-fat, medium-protein, low-carbohydrate (starch and sugary) system. Mostly, 70% of your calories are from fat, 25% from protein and 5% from carbohydrates. I will explain in detail about the macro keto and how to calculate it. Also known as ketogenic dieting or ketogenic diet, it is classified in the scientific community as among Low Carb High Fat diets, LCHF or low-carb high-fat dieting.
The idea of the keto diet is to minimize carbohydrates to a maximum (less than 20 to 50 grams of carbohydrates per day), and thus the body relies on fat (from food and from the body) as a source of energy instead of glucose, as it is rumored that low insulin levels in the body stimulate fat burning ( Insulin is a hormone secreted by the pancreas to deal with glucose in the blood and transports it to cells to provide energy).
It should also be noted that the keto diet is not high in protein (Atkins Diet is high in protein, fat and low in carb), because high protein is converted to glucose by the process of glucononeogenesis and reduces the manufacture of ketones in the liver. In this article I will explain to you the amount of protein required during the keto diet, because there is a common mistake in Arabic articles, where they describe large amounts of protein.
The brain relies mainly on glucose for energy. When carbohydrates are severely cut, your liver begins to break down fats and convert them into Ketons in the liver. These ketones travel in the blood and nourish the brain and the rest of the cells (since the fatty acids are not transmitted to the brain because of the blood barrier), and your body is then in the state of Ketosis.
Keto diet followers measure ketones in their blood or urine to ensure they are in the ketosis state. The level of ketones in the blood at the time is higher than 0.5mmol / L and ideally from 1.5 to 3 mmol / L, higher than that your body is in a dangerous condition called Ketoacidosis or ketoacidosis, I will talk about it later in the keto damage section.
It should be noted that measuring the amount of ketones in your blood is unnecessary, as keto followers depend on an easier method which is to follow the side effects of the keto diet, such as increased urination, dryness of the throat, mouth and sweat changing. It should be noted that fasting also prolonged periods increases ketones in the blood (thus epilepsy was treated in the past). Since you cannot fast throughout life, the keto diet is used to achieve ketosis instead of fasting.
