What is a ketogenic diet?

Diet is always stressful for the body. The body gets used to changing the diet for 7-10 days. Many people feel irritated and physically ill during strict diets.

Especially for people who do not want to endure the constant feeling of hunger, a "keto diet" has been developed.

Ketogenic diets are gaining popularity in health and wellness environments

Description of the keto diet as a percentage of the daily diet:

  • 55-65% fatty foods;
  • 25-35% protein dishes;
  • 5-10% glucose from carbohydrates.

The keto diet for weight loss often allows you not only to maintain physical shape, but also to remove body fat and build muscle. The ketogenic diet causes "ketosis" in the body, a mechanism that is triggered by a lack of carbohydrates. At this time, the body begins to use only fat as a source of energy. In the process of ketosis, ketone bodies are formed in the body. Their increased amount is dangerous to human health, so it is very important to drink enough fluids.

Basic rules

Basic principles of the keto diet:

  1. The drinking regime includes at least two liters of water a day.
  2. The maximum amount of carbohydrates is 40 grams per day.
  3. Be sure to eat fiber, preferably green vegetables.
  4. To make the transition to a new diet more relaxed, consume equal amounts of protein and fat in the first week.
  5. Eat the usual amount of carbohydrates twice a week so as not to cause a deficiency.

The ketogenic diet for weight loss should be applied without fanaticism. When calculating the protein and fat of the keto diet it is necessary to rely on the state of the body, its indicators and energy reserves.

For the period of such a diet it is necessary to reduce the calorie content of the diet by 15%. If a woman consumes 2500 kcal per day during a fat diet, the food is reduced to 2100 kcal.

The following are assigned to them:

  • 1200 kcal for fat;
  • 600 kcal for protein;
  • 300 kcal for carbohydrates.
