Body Mass Index (BMI) calculates body fat according to the relationship of weight and height.

A BMI between 20-25 is considered normal, indicating a healthy weight for most people.

A BMI less than 20 is considered low for most people; a low BMI may be indicative of being underweight and may cause health problems.

A BMI greater than 25 is considered high for most people; a high BMI may be indicative of being overweight or obese and may increase the risk of developing health problems.

The Ideal Body Weight (IBW) calculator 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.

Our Calorie Calculator provides a calculation for weight maintenance based on information you provide (height, weight, age, and activity level). The calculation may be high if you are overweight or low if you are underweight.

Choose a healthy weight for yourself (a target weight) to use 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).

Please consult to a registered dietitian if you have questions regarding your weight and calorie intake.
