Waist circumference (WC) is a stronger predictor of type 2 diabetes risk than body mass index (BMI), and WC identifies cardiometabolic risk in individuals with normal BMI who would otherwise be missed by BMI-based screening.

Ask your doctor to measure your waist circumference. If you are a man, a measurement over 40 inches (102 cm) or a woman over 35 inches (88 cm) indicates higher risk for heart disease and diabetes, even if your weight (BMI) is normal. This measurement helps catch risks that standard weight checks miss.

GoodSupportsHIGH confidence
The relationship between WC and clinical outcome is consistently strong for diabetes risk, and WC is a stronger predictor of diabetes than is BMI... Data from many large population studies have found WC to be a strong correlate of clinical outcome, particularly diabetes, and to be independent of BMI.

Why this rating

Based on large epidemiological studies and consensus of expert panels, though causality of specific mechanisms is complex.
