What is Body Mass Index (BMI)?
The Body Mass Index (BMI) is a widely used screening tool that provides an estimate of body fat based on a person's height and weight. While it does not measure body fat directly, research has shown that BMI correlates moderately with more direct measures of body fat. It is a simple, inexpensive way to screen for weight categories that may lead to health problems.
How to Interpret Your Results
Your BMI score indicates which weight category you fall into. Here is the standard breakdown for adults:
| BMI Range | Category |
|---|---|
| Below 18.5 | Underweight |
| 18.5 – 24.9 | Healthy Weight |
| 25.0 – 29.9 | Overweight |
| 30.0 or Higher | Obese |
Calculation Example
If an individual weighs 75 kg and is 1.8 meters (180 cm) tall, the calculation would be:
BMI = 75 / (1.8 * 1.8) = 23.15
In this example, the individual falls within the "Healthy Weight" range.
Important Considerations
While BMI is a useful general guideline, it has limitations. It does not account for muscle mass, bone density, or overall body composition. For example, athletes or bodybuilders may have a high BMI due to increased muscle mass rather than high body fat. Always consult with a healthcare professional for a comprehensive health assessment.
