It's still a period of growth, so don't lose weight at will. Improper methods will have side effects.

First of all, you can't go on a diet, but it's a good way to lose weight as long as you have a balanced diet.

Exercise 1 hour or more every day, because exercising 1 hour or more will really consume your fat.

In terms of diet, it is certainly better not to touch snacks and drinks.

Fish and lean meat should also be eaten.

Work hard, I hope you can succeed!
