The keto diet, or the keto diet, the ketogenic diet, ketogenic, all these names revolve around a diet that began as a treatment for epilepsy patients in the 1920’s to reduce epileptic seizures, and was later used as part of a treatment program for some cancers. It is called ketogenic because it depends on ketone bodies as its primary source of energy.

Then the keto diet spread to lose weight, so what is the keto diet? What are the positives and negatives of the keto diet? Details are as follows:

The keto diet:

The ketogenic diet depends on high intake of fat and protein (75% fat and 25% protein) and very small proportions of carbohydrates from non-major sources that do not exceed 5% of a person’s daily intake, which is estimated at 50 grams per day.

How the keto diet works:

Usually the body depends on the calories from carbohydrates that come from sugar as the main source of energy, and this method is preferred because it provides the body with energy quickly.

What happens in the keto diet is that the body does not eat any source of carbohydrates, which lowers the levels of the hormone insulin in the blood, and this causes the body to search for another source of energy, so it begins to break down fats and amino acids inside the liver to produce a new type of energy, which is ketone bodies, and this happens. After it enters the body through a phase called the ketosis, or ketosis, or ketosis, so the main source of energy becomes fat instead of carbohydrates.

Entering the state of ketosis (ketoses):

After 3 days of cutting the intake of carbohydrate sources, the levels of glycogen or glycogen in the blood decrease. The body resorts to withdrawing the stores of glycogen from the muscles and liver, and the body is forced to produce ketone bodies from the liver as an energy substitute after going through a series of reactions inside the body, A person is in this stage and the symptoms of entering the state of ketosis are called (temporary symptoms) and they are:

Headache and headache.-


Feeling very tired and general body fatigue.-

.Feeling of a fever or the flu-

.Feeling of pain in the extremities of the body-

After 6 days of following the keto diet, the following symptoms appear:

-Dark urine due to excretion of excess ketone bodies in the urine (you should drink 2 to 4 liters of water daily).

.( Severe constipation (flaxseeds are recommended-

.Or excessive diarrhea due to the excretion of fats through the digestive system-

It takes 4 days for the body to start showing symptoms of ketosis, 10 days to enter ketosis, and 120 days to adapt and reach the highest levels of ketone body production

Types of keto diet:

There are 4 types of the ketogenic diet:

-The basic ketogenic system (standard): depends on food intake of 75% fat, 20% protein, and 5% carbohydrates from indirect sources (such as cheese and vegetables).

-The cyclical ketogenic system: It depends on following the basic ketogenic diet for 5 days a week, while high carbohydrates are eaten two consecutive days of the week.

-The targeted ketogenic system: It depends on following the basic ketogenic diet, with eating carbohydrates only before exercising.

-High-protein ketogenic diet: Food ratios are 60% fat, 35% protein, and 5% carbohydrates.

Other ketogenic diets:

There are some diets that rely on ketone bodies but are less conservative in eating carbohydrates, such as: the Atkins, Paleo, and Dokan diet.
