Thin body but Fat face

I'm 22 year old male.
My body is quite thin but my face is fat.
I wasn't like that when I was 3 years ago.
What can I do to make my face thinner?
eg. Diet or what.

Thanks alot.

It sounds like that is just your body structure.  You are thin now but trust me, you will begin to fill out the rest of your body when you are around you 30's.  Don''t look at it as a defect.  It's just what your body is doing now that's all.  It won't stay like that forever.
