Ok im 14 and been goin though puberty since about 11. And ive already grown alot and lately ive been really hungry. I eat a good lunch at school then after working out for about an hour after school i usally eat a sandwich when i get home which is at 4 then at about 5:30-6 i eat a big dinner then ill eat again at 8:30 then im hungry again at 11 its really really annoying. Is it because ive been working out lately or what?
