How on earth can i gain weight?

when i needed to gain a few pounds i ate every thing that was bad for me, i would eat 60 rocky bars a day and that sure helped me but it was the wrong way to do it. now i eat right and 3 times a day and i am 5ft 6inc and 9 stone and i am so happy with that because i was 7 stone and looked like death warmed up, just eat right and you will get there, good luck, its nice to see that there still are people out there that want to gain some not lose it like the people we see on TV good luck
