Body Mass Index (BMI) Calculator

The Body Mass Index (BMI) is often used to
assess how much an individual's body
weight departs from what is normal for a
person of his or her height. Typically a BMI
of less than 18 is considered underweight,
while a BMI greater than 25 is considered
overweight and above 30 is considered
obese.
Basal Metabolic Rate (BMR) Calculator

Basal metabolic rate (BMR) is the amount
of energy expended to maintain the normal
functioning of the vital organs, such as the
heart, brain and other internal organs. As
you age, your BMR tends to decrease
along with the loss of lean body mass.  
Waist to Hip (W/H) Ratio

Waist to hip ratio (W/H) is simply the waist
size divided by the hip size.
