What should you know about losing weight quickly?
The faster you lose weight, the more stress your body experiences. The body can react to this stress in the following ways:

Calorie absorption
In everyday life, a person absorbs different amounts of calories. Much depends on the type of food and the state of the stomach and intestines, but we rarely absorb 100% of the calories we get from food. Often, the numbers fluctuate between 70 and 80%. That is, having eaten a burger or buckwheat for 400 kcal, you will receive only 280-320 kcal. A person lives like this and goes on a diet with this yoga feature of the body https://gracify.co.uk.

However, as soon as you expose your body to significant stress, it responds by increasing the amount of calories it absorbs. This is a defense mechanism designed to save you from starvation. Agree, it is stupid to throw away 30-20% of the energy you receive while your entire body is suffering from a calorie deficit.

This phenomenon explains how a person starts to lose 2000 kcal, reduces to 1800 kcal per day and the progress stops. It would seem that there are fewer calories, but the weight loss has stopped. The reason is the absorption of calories and a protective reaction.
