I'm 14 years old, i am female and i started drinking Boost Plus to gain weight. I do hip hop dance, and i exercise on a regular basis but my mom always tells me that when i'm older, i'm gonna have a weight problem and when i start gaining weight i won't stop. is this true? Right now i'm 5'7, measurements are 34C-25-37 and i weigh 123. Will i become overweight?
