Hi I am a 17 year old girl, and I wake up at 6:00 every morning go to school until 2:50, which involves a lot of walking around and going up and down stairs. Then I come home and usually exercise for about an hour each night. I am 5'7" and 128 lbs.
If you are over your target weight eat a little less, if you are under your target weight eat a little more, somewere between 128# and 134#. The number of calories would only be a rough guess.
