Frequently Asked Questions
What is Body Roundness Index (BRI)?
BRI is a formula that estimates body shape and visceral (abdominal) fat using only your waist circumference and height. It was developed as a more direct measure of central fat than BMI.
How is BRI different from BMI?
BMI is based on total weight relative to height and does not distinguish between fat and muscle or account for fat distribution. BRI focuses specifically on waist circumference, making it more sensitive to visceral fat, which is more strongly linked to cardiovascular and metabolic risk.
What is a healthy BRI range?
Research associates a BRI roughly between 3.41 and 5.46 with lower health risk, with values further outside that range associated with progressively higher risk.
Do I need any special equipment?
No, you only need a tape measure for your waist and your height. No scale or body scan is required.
