How Many Types Of Keto Diets Are There?

What is the keto diet?

What is the definition of a keto diet? The ketogenic diet is a low-carb diet in which the body produces small fuel modules in the liver called ketones, which are used for energy. Ketones are an alternative fuel for the body, used when there is a shortage of sugar (glucose) in the blood. By eating very few carbohydrates, moderate amounts of protein, and high levels of natural fats, ketones are produced. They are made in the liver from fat and used throughout the body for fuel.

Keto diet explanation: The term keto diet is the adaptation of ketogenic diet, that is, ketogenic diet. It refers to a food model whose main mission is the creation of ketone bodies , metabolic compounds generated in the liver in response to the lack of energy reserves.

This diet is related to the drastic reduction of carbohydrates and their replacement by fats, which exposes the body to a metabolic state called ketosis, where the body, running out of energy reserves, has to resort to fats to use them as fuel. immediate.

The keto diet lowers blood sugar and insulin levels, and causes a transition in the body’s metabolism in which carbohydrates are replaced by fats and ketones.

How does the ketogenic diet work?

The entire body switches its fuel supply to run almost entirely on fat. Insulin levels become very low, allowing fat burning to increase dramatically. The body is in a state of ketosis when it produces ketones.

The body obtains glucose from simple carbohydrates, such as milk, sugar or fruit, or from complex carbohydrates, such as cereals, flour, pasta or legumes.

The glucose that circulates in the blood, is stored in the liver or in the muscles in the form of glycogen, is the main source of energy for the entire body, especially for the brain and heart. So, as long as glucose, or failing that glycogen, exists, the human body does not use its fat stores.

In this regard, the keto diet consists of reducing the intake of carbohydrates and increasing the content of proteins and healthy fats, in proportions of between 50 and 60% fat, 20 to 30% protein and 10%, or less carbohydrates.

The keto diet causes the body to switch its fuel supply to run almost entirely on fat. This causes insulin levels to become very low, which in turn allows fat burning to increase dramatically.

  • It helps patients with type 2 diabetes. Its benefit for diabetic patients is that it controls blood sugar levels, and on the other hand, it decreases and reduces the negative impact of high insulin levels.
  • Used in the prevention and treatment of certain types of cancer. Reducing carbohydrate intake lowers glucose levels, which is the fuel that fuels cancer cells. This diet is also used to treat many types of cancer and reduce the growth of tumors.

What are other benefits of the ketogenic diet?

  • appetite control
  • Steady energy and mental performance
  • Control blood sugar and reverse type 2 diabetes . Blood sugar levels are controlled, lowered and the negative impact of high insulin levels is reduced.
