Ok, so i'm just trying to norrow down how many calories i should eat in one day, now i've been to livestrong.com and they say somewhere around 2000 cals, but i'm usually standing and doing chores around the house like cleaning up, i'm 15 and not sure how much i weigh (probably not a-lot), i just want to know how many calories i should have in a day. Thanks_
