Questions people ask

What is a healthy BMI?

For most adults, 18.5 to 24.9 is considered a healthy range by the WHO.

Is BMI accurate for everyone?

No. BMI does not tell muscle from fat, so athletes can score high. It is a screening tool, not a diagnosis.

Are there different cut-offs for Asians?

Some health bodies use lower cut-offs for South Asian adults, with 23 or more counted as overweight.
