To maintain your body weight, multiply the number of pounds you weigh now by 15 calories. This number represents the average number of calories used up in one day by a moderately active person of your weight.
(i.e. your weight is 200 x 15 = 3000)
If you're sedentary or get very little exercise, multiply your weight by 13 instead of 15. Less-active people burn fewer calories.
