Body Mass Index (BMI) is the preferred method of measurement
![]() |
for doctors and researchers studying obesity. The formula used to calculate an individual's BMI is weight (in kilograms) divided by height (in meters) squared.
Although it is correlated with body fat, its implications differ according to age and sex. Women generally have more body fat than men, for example. Furthermore, a muscular athlete and an out-of-shape person can have the same BMI score. Older people tend to have more body fat than younger adults with the same BMI. Interpretation of the BMI scores, therefore, is not an exact science.
In adults over 20 years of age, the BMI chart shows BMI scores of less than 18.5 as underweight, while the normal range should be between 18.5 and 24.9. Those with scores falling between 25.0 and 29.9 are deemed overweight, while those at 30.0 and above are classified as obese. It is important to note that BMI is only one indicator of relative health or risk for disease. With weight control and exersize, BMI scores can be brought into the healthy range, and overall health can be considerably improved.
