Maybe bargl means Bioelectric Impedance Analysis? A cursory internet search also indicates BIA is suspect as a one-time measure.

- bargl 10y agoOK so I have this and I thought that the BMI it computed was based on tracking the fat to everything else based on BIA. But I may be way off here. https://www.fitbit.com/aria https://www.fitbit.com/aria I see that Fitbit tracks this as BodyFat % not BMI. Not sure if that's accurate.
- raffy 10y agoBIA is pretty bad. Here are ~1300 Fitbit Aria measurements matched against 7 DXA scans. The Fitbit bodyfat data (teal) is just random noise and can barely detect considerable changes in body composition. http://i.imgur.com/J4Ls2bQ.png http://i.imgur.com/J4Ls2bQ.png
