Thread: I can't gain weight.?

I can gain weight in muscle but not in fat, every time i eat i get hungry again after about half an hour and i hate it. I try to eat as much as i can but i never seem to be able to gain any weight at all and it makes me feel really bad since i go hungry almost all the time. My parents told me its because i have a high metabolism and neither of them can gain weight either but i really want to. What am i to do?

Eat foods higher in calories.
