What is BMI?

Body Mass Index (BMI) is a simple calculation using a person's height and weight. The formula is BMI = kg/m² where kg is a person's weight in kilograms and m² is their height in meters squared.

BMI Categories

Below 18.5 – Underweight
18.5 to 24.9 – Normal weight
25.0 to 29.9 – Overweight
30.0 and above – Obese

Limitations of BMI

BMI doesn't distinguish between muscle and fat. Athletes may have a high BMI due to muscle mass. It also doesn't account for fat distribution, age, or gender differences.

When to Use BMI

BMI is a useful screening tool but shouldn't be used as a diagnostic tool. For a complete health assessment, consult with a healthcare professional who can consider other factors.
