Personally, I think we should be healthy as long as we keep a regular diet and balanced nutrition.
Maybe you lost too much weight at once.
Two and a half months, 22 kg is too fast.
You can eat more gradually.
Take your time.
For example, eat an extra cucumber at noon today
Stick to it for a week and then add it bit by bit.
Plus your previous food intake
But definitely eat less greasy and staple food.
No dinner.
Don't be too hungry
Mainly to maintain the diet structure.
Reduce the amount of exercise.
Then stick to it for half an hour to an hour every day.
The most important thing now is health.
