How to lose fat on your thighs and calf?

I am 12 years old and i want to lose fat in my thighs and calfs. I am a size 3 in skinny jeans. I don’t know how to lose fat in my calfs without adding mussle. I don’t want to add mussle but i still want to lose fat.

Cardiovascular exercises, such as jogging, swimming, dancing, etc., will help burn fat. Combine that with a healthy diet and you won’t put more fat on than you burn.
