I found a few, but thier results are well iffy at best. FIrst of all, noone has the same metablic rate as someone else, or does the same thing as someone else during a day.

This one says for basal calorie needs(ie calories for my blood to pump, body to work, what have you) I need about 1900 calories being 5'11'' and 180 pounds. It also says I need about 2600 calories for all the activity I do during the day. I'm pretty sure I'm active enough(just always on my feet, walking) that its a little higher.
Remember a woman needs alot less calories(still women naturally have higher lvls of body fat, and less mussle) then a man does, and that dieting can lower your MBR.
