Do you think you look fat? some peeps may have mussel, no fat and weight alot. Im also 5'5 and I used to be 175, I thought I was fat, but only in the billy. I dunno bout girls cause their fat soppose to be in thighs, butt, and chest. and sometimes they dont look all that fat. I wouldent say you have a weight problem, but maybe in the slightly heavy side. But if your comfy with the way you are, than that is Kewl. I dont like to picture 13 year olds or young people on diets, but if you plan to do something, just take it slow. Or lot of exsercize is good wit wata.
