What your BMI means
BMI (Body Mass Index) is your weight in kilograms divided by your height in metres squared. It is a quick screening number used by doctors worldwide — it does not measure body fat directly.
| BMI | Category (WHO, adults) |
|---|---|
| Below 18.5 | Underweight |
| 18.5 – 24.9 | Healthy range |
| 25 – 29.9 | Overweight |
| 30 and above | Obesity range |
Good to know
- Many Asian health bodies use lower cut-offs (overweight from 23).
- Muscular people can have a high BMI without excess fat.
- BMI is not designed for pregnancy, children or teenagers.
