Asian BMI criteria (Korea)
- Below 18.5: underweight
- 18.5 โ 22.9: normal
- 23 โ 24.9: pre-obese (overweight)
- 25 โ 29.9: obesity class 1 / 30 โ 34.9: class 2 / 35+: class 3
The WHO criteria start "overweight" at 25, but Asians face higher metabolic risk at the same BMI, so Korea uses 23 as the overweight threshold.
