What is BMI?
Body Mass Index is weight in kilograms divided by height in metres squared. It is a quick screening number, not a diagnosis.
Standard adult BMI categories (WHO)
- Below 18.5 — Underweight
- 18.5–24.9 — Normal weight
- 25–29.9 — Overweight
- 30 and above — Obese
BMI doesn't distinguish muscle from fat and isn't intended for children, pregnant women or athletes. Talk to a doctor for health advice.
