The Ideal Body Weight (IBW) calculators will calculate for an adult medium body frame size. For a smaller frame size subtract 10%, for a larger frame size add 10%. Frame size is calculated by dividing height in centimeters by wrist circumference in centimeters to get a radius (r). The radius (r) is then compared to constants. Wrist circumference is measured at the wrist crease, the area between the wrist bone and the bottom of the hand.

The Calorie calculators provide information for weight maintenance. This is based on the information you provide (height, weight, age, and activity level). If you are overweight or underweight the calculation may be high or may be low. You can choose a healthy weight for yourself and use that weight in the calculation. If the goal is to lose weight, 1 pound per week, subtract 500 calories per day from the current daily intake. If the goal is to gain weight, 1 pound per week, add 500 calories per day from the current daily intake. Theoretically this works because 1 pound of fat represents 3500 calories (500 calories per day multiplied by 7 days equals 3500 calories). If you have questions regarding your weight and calorie intake visit a registered dietitian.
