The Basal Metabolic Rate (BMR) calculations above will give you the minimum number of calories you body needs during inactivity, just to keep your organs running. the equation takes into account weight, height and age and is different for men and women.
You should use your BMR figure to establish the minimum number of calories your body will use in any given day, even if you do no exercise. It will allow you to gauge your calorie intake accordingly. If your BMR comes out at say 2500, then you know that to lose weight you would need to keep your calorie intake under this figure. If you do exercise that burns an additional 300 calories than the number of calories burned would be 2500 + 300 = 2800 calories. If your intake through food was 2300, you would have a deficit between calories taken in, and burned of 500 calories. If you did this consistently for one week you would lose approx 1 pound in weight.
