Hello! I am a 14 year old girl, I am 1. 67 tall and I weigh 49 kilograms. My friends say that I am quite thin and I wonder what I need to eat to gain a few pounds, because I have not yet formed, in some places I have not yet started and this also matters from the pounds. Can you tell me what to eat or if you can make me a program? Please, no offense. :)
