Frequently asked questions
- How accurate is the RFM formula?
- In the 2018 validation study, RFM estimated DXA body fat with less error than BMI for the majority of adults. It remains an estimate, not a measurement, and accuracy varies between individuals.
- Is RFM better than BMI?
- RFM directly uses waist size, so it reflects central fat that BMI ignores. Two people with the same BMI can have very different RFM values.
- Do I need to know my weight for RFM?
- No. RFM is unusual among body-fat estimates because it needs only height and waist circumference, not body weight.
