Little sister, you are still growing. Don't lose weight easily. Now you don't know what will happen in the future. It will change.

If you usually eat more vegetables and drink more yogurt, it is good for your skin and you can lose weight at the same time.

If you have time in the morning or evening, do more exercise, dance, jump rope and hula hoop have good effects and are also helpful for growth.

In short, don't be too demanding. You are still young. No medicine or anything. It is not good for your development. I hope my answer is helpful to you.
