What is BMI?

Body Mass Index (BMI) is a simple screening measurement that estimates whether your weight is healthy relative to your height. It's calculated as weight in kilograms divided by height in meters squared (kg/m²). While BMI does not directly measure body fat and doesn't account for muscle mass, it remains a widely used starting point for assessing weight-related health risk.

BMI categories for adults

Below 18.5 — Underweight
18.5 – 24.9 — Normal weight
25 – 29.9 — Overweight
30 and above — Obese

Limitations

BMI is a general guideline, not a diagnosis. Athletes with high muscle mass, older adults, pregnant women, and children may need different interpretations. Always consult a healthcare professional for personalized advice.
