Why Singapore uses different BMI thresholds
Singapore's Health Promotion Board (HPB) defines overweight as BMI ≥23.0 and obese as BMI ≥27.5 — lower than the WHO global cutoffs of 25.0 and 30.0. Research shows Asians accumulate visceral fat and face metabolic risk at lower BMI values than people of European descent. HPB vs WHO explained →
