Here is a neat site I wanted to share. The link will take you to a page click the men or women, then fill in the boxes. It asks you height, current weight and your age, then calculates how many calories you need to eat to maintain that weight.

You would need to eat 500 calories a day less to lose 1lb a week.

Also if you go to the top of this page and go to resources, scroll down to the very bottom and there is a diet center there. You'll see different calculators!! Its awesome.
