Asian BMI Thresholds (Pakistan/India/Bangladesh)
For South Asian populations including Pakistan, India, and Bangladesh, health organizations recommend lower BMI thresholds: overweight starts at 23.0 (not 25.0) and obesity at 27.5 (not 30.0). This is because South Asians tend to carry more body fat at lower BMI values compared to Western populations.
