Understanding Your BMI

BMI ≤ 18.5 (Underweight)

A lean BMI can indicate that your weight may be too low. You should consult your physician to determine if you should gain weight, as low body mass can decrease your body's immune system, which could lead to illness.

BMI 18.5 - 24.9 (Normal)

People whose BMI is between 18.5 and 24.9 possess the ideal amount of body weight, associated with living longest, having the lowest incidence of serious illness, and being perceived as more physically attractive than people with BMI in higher or lower ranges.

BMI 25 - 29.9 (Overweight)

People falling in this BMI range are considered overweight and would benefit from finding healthy ways to lower their weight, such as diet and exercise. Individuals in this range are at increased risk for a variety of illnesses.

BMI > 30 (Obese)

Individuals with a BMI over 30 are in a physically unhealthy condition, putting them at risk for serious illnesses such as heart disease, diabetes, high blood pressure, gall bladder disease, and some cancers. These people would benefit greatly by modifying their lifestyle.
