Calculate your Body Roundness Index to assess body shape and health risk from abdominal fat.
The Body Roundness Index (Thomas et al., 2013) models the human body as an ellipse to estimate roundness. Higher BRI values indicate more body fat, particularly visceral fat associated with metabolic disease.
Body Roundness Index uses height and waist circumference to estimate body shape as an ellipse. It correlates well with body fat percentage and visceral fat, providing insight beyond BMI.
