High School is great. It's also scarry. And whatever weight you are, if you think you'll be a great cheerleader, do it. But there will be A LOT of speculation. And that doesn't go away with the fat you burn. Being skinny doesn't make you popular. And many people are popular because they are mean. Try to focus on being a good student, eating healthy, exercising, having fun, and concentrate on where you will be once you're out of High School.
