Bioelectrical impedance analysis (BIA) (im-PEE-dance)
A way to estimate the amount of body weight that is fat and nonfat. Nonfat weight comes from bone, muscle, body water, organs, and other body tissues.

BIA works by measuring how difficult it is for a harmless electrical current to move through the body. The more fat a person has, the harder it is for electricity to flow through the body. The less fat a person has, the easier it is for electricity to flow through the body.

By measuring the flow of electricity, one can estimate body fat percent.

Body mass index (BMI)
A measure of body weight relative to height. BMI can be used to determine if people are at a healthy weight, overweight, or obese.

To figure out BMI, use the formula found in Helpful Tools.

A body mass index (BMI) of 18.5 up to 25 refers to a healthy weight, a BMI of 25 up to 30 refers to overweight and a BMI of 30 or higher refers to obese.
