If you lose weight ... you should be careful with little girls, because malnutrition will affect their normal development (if your period hasn't come yet, but it's already 170 ... should it be there? ), I will regret it later. ...
You can exercise for your fatter parts every day, twist your waist more, and do squats with standing posture. Don't trust diet pills!
Snacks, especially fried food and ice cream, must be banned. You can eat less for dinner. It is most effective to keep your mouth shut.
Besides, a standard weight like yours is very healthy. I can understand your desire to be light, but don't be too eager for success, not to mention losing your health for beauty.
