If you’re dieting, you’re counting calories – or at least you should be. If you know how many calories you naturally burn each day, you can start planning your food and exercise regimen. Food adds calories, while exercise burns calories. There are about 3,500 calories in each pound, so you’ll need a net loss of 3,500 calories to lose one pound.

We all burn calories at different rates. Put in your personal statistics in this handy little calculator to check out the amount of calories that your body requires in a typical day. This calculator is based on the Basal Metabolic Rate (BMR) developed by Harris and Benedict, . Using the height, weight and age – and multiplied by an activity factor – you can calculate your caloric needs per day.
