Most online calculators use WHO global thresholds (BMI 25+ for overweight, 30+ for obese). For Indians, this under-reports risk. Research from AIIMS and ICMR has established stricter cut-offs for South Asian body composition — BMI 23+ overweight, 25+ obese, waist circumference > 90 cm (men) or > 80 cm (women) indicating abdominal obesity. All NuvaHealth calculators apply these Indian-specific thresholds.
