Healthy Food Chart

Im a 17 year old girl that has a height of 4″12 and weigh around 165 lb. I see alot of girls my age that have a normal weight or are relly thin, and i see magazines and i know im better than that, and shouldnt listen to them, but i cant help it. One hing is for sure, though. I dont want to lose weight unhealthy. I want to do it the right way so i really need guidance from somebody who has been in my shoes. Please and thank you!
