Waist Circumference Risk Reference
Your waist against WHO/IDF action points including the lower South-Asian thresholds — central-fat context.
Where fat sits matters as much as how much — abdominal (visceral) fat is the metabolically active kind, which is why waist measurement adds information BMI misses entirely. South Asians accumulate visceral fat at lower waists, so the IDF sets the action point at 90 cm (men) / 80 cm (women), notably below European levels. Measure at the midpoint between the lowest rib and the hip bone, after a normal breath out. Context for lifestyle and clinician conversations, not a diagnosis.
