BMI
BODY MASS INDEX - BMI

Calculating BMI is one of the best methods for population assessment of overweight
and obesity.  It is a useful screening tool to identify possible weight categories that
may lead to health problems for adults.  BMI calculations are recommended and
approved by the United States Department of Health and Human Services’ Centers
for Disease, Control, and Prevention (CDC).

BMI can be considered an alternative for direct measures of body fat.   The following
chart contains the published and accepted BMI categories from the CDC:
BMI
Weight Status
Below 18.5
Underweight
18.5 – 24.9
Normal
25.0 – 29.9
Overweight
30.0 and Above
Obese
more body fat than men, and older people, on average, tend to have more body fat
because of increased muscularity rather than increased body fatness.  Although
some people with a BMI in the overweight range (from 25.0 to 29.9) may not have
excess body fatness, most people with a BMI in the obese range (equal to or greater
than 30) will have increased levels of body fatness.
