I only recently started counting (Feb 18). I use livestrong and just plugged in my information. It spit out a number which decreases a little bit with every pound I lose. I know nothing about the science of it. I just decided I would try what they suggested and see what happened. I also log my exercise and it ups my calories, although I try not to take those numbers for granted (ie: eat them all up every day).
My suggested calories for a 53 yr old, 5'5", Light Activity, before exercise is 1110, if I say I want to lose 2# per week. If I want to lose 1# per week the calories are quite a bit higher...of course, I haven't been perfect foodwise, either. I find I try pretty hard to track right and to stay within my range.
I've lost 14# since I started on Feb 18. That works for me.
