Work out overweight risk instantly with clear inputs, formula shown and shareable results.
BMI and waist circumference capture different aspects of risk, so clinical guidelines assess them together. A BMI of 28.5 with a 98 cm waist scores 2 plus 2 - high risk for a man, since central fat compounds the effect of excess weight. A high waist at normal BMI still raises risk, which is why one measure alone is insufficient.
Composite score
score = BMI points (0-6) + waist points (0-4)
Waist thresholds
men 94 and 102 cm; women 80 and 88 cm
These figures are population-average estimates, not a medical assessment or diagnosis. Body composition equations carry errors of several percentage points, and healthy ranges vary with age, ethnicity, muscularity and medical history. Discuss weight or body composition goals with a qualified clinician or dietitian.
Yes - normal weight central obesity carries measurable metabolic risk, which is exactly why waist is assessed separately.
Waist. Visceral fat responds quickly to modest calorie deficit and aerobic exercise, and it is where most of the risk sits.
