*BMI= Body Mass Index- a measurement of body fat that uses a ration of weight to height.

*Formula:

*BMI= weight in pounds * 703/height in inches squared

*Example of figuring your BMI

A 15 yr. old male weighs 137 pounds and stands 5 feet 6 inches(66 inches).

*137*703= 96,311

*66*66= 4,356

*96,311/4,356=22

*For adults overweight is BMI between 25 and 29.9

*For teens refer to the chart on page 152 of the textbook
