(One of my classmates lost weight after three months of college entrance examination 10 kg)

But then I didn't insist and put on weight again.

Be sure to persist.

Don't think that you can eat and drink because you are thin.

Classmate, you are only in junior high school.

Be sure to eat what you deserve.

Drink what you should.

Are you growing physically now?
