How can I lose 6 pounds fast?

For losing weight your not exercising nearly enough. Try doing a sport for at least an hour to work up a good sweat. If you want to lost weight fast, the best option is to skip meals. its not healthy but it gives results. my suggeston would be that you skip dinner because you burn the least calories when your sleeping (duh). If your really desperate, eat 1 meal a day and you'll see results fast (but you'll only keep off the weight with regular excersing and controlling your calorie intake). DRINK WATER!!!! Hydration is goddam important. its not like itll give you calories >.> also your 12 yrs old. you've probably still got a bit of growth spurt in you so dont worry.
