160 is 95 kg tall and not fat.

If you have to force yourself to lose weight for ten days, you may rebound ~

So it's best to take your time.

Because you're not that fat.

Pay attention to eat something light, just add milk or soybean milk for breakfast.

Eat more vegetables and lean meat for lunch and eat less.

Eat only vegetables and fruits for dinner.

If you are hungry, drink tea and milk. After a while, my stomach will get smaller and I don't want to eat many snacks.

Try to walk to school, and walk briskly.

If you can't keep skipping and running, forget it, or you will build muscles ~!

All right, that's all. I wish you success!
