How to lose weight with water for a week by 10 kg?

Rapid weight loss on hunger strikes and fasting days is impractical and can be dangerous to health.

When you lose weight on hunger strikes, when you only drink water, the weight goes away quickly, but you do not solve the main task – it does not change your eating behavior, and you do not work with a carbohydrate addiction. This means that sooner or later you will return to the old way of eating and the weight will return, and usually even more than before the hunger strike.
For more clarity, let's look at a case from practice.

A patient came to us with the goal of weight loss. Its weight at the time of treatment was 175!!! Ru. When she weighed 115 kg, she decided to lose weight on a hunger strike, drinking only water. Thus, she lost weight for 30 days and lost weight by 30 kg. She began to have serious health problems: there was a smell of acetone from the mouth, there were gallstones and she stopped starving. Over the next 4 months, she not only returned the lost 30 kg, but also added another 30 and thus her weight increased to 175 kg!
