Preguntas
Why is Asian overweight 23, not 25?
WHO expert groups noted higher metabolic risk at lower BMI in many Asian populations. India, Japan, and several ASEAN guidelines use 23/25.
Is BMI a diagnosis?
No. It is a screening index. Waist, body fat, and clinical history matter more for decisions.
