Frequently Asked Questions

Why is BRI better than BMI?
BMI ignores body shape. A muscular athlete can register obese; a thin person with belly fat can register normal. BRI uses waist + height to measure visceral-fat risk directly. NEJM 2024 study (33K adults, 20-yr follow-up) found BRI predicted mortality more accurately than BMI.
BRI scale?
<3.41 low risk · 3.41–4.45 moderate · 4.45–5.46 high · >5.46 very high all-cause mortality risk.
