TURBO JAM HELP AND WEIGHT LOSS!! QUICKLY! HELP!?

i'm 15 years old and about 200 pounds now. I know its not healthy but i'm not to the point where i can't do nothing. i'm 5 3' and i play basketball. But its only practice once a week for 2 hours and i walk to and from school everyday (15 min.) I'm a female. My dad bought me this turbo jam awhile ago and I REALLYYYYY need to start exercising.I'm thinking about doing the AB JAM, FAT BLASTER, AND CARDIO PARTY in one day because my body is really starting to look disgusting. I have alot of belly fat that I HAVE to get rid of. ANY HELP OR SUGGESTIONS ON MY EATING PLAN. its hard for me to eat in the morning also.
