Insanity work out for 14yr old ?

Im a 14yr old girl who wants to loose weight and get in good shape before high school. Im about 200 pounds, and I wanted to know if it can work for me. I mostly want to loose fat in my stomach, Do you think it will be too hard for me? I know i can push myself to work hard everyday, but im just not sure if its such a good program for a person my age.
