Aria 2 body fat % keeps changing

[tvin17]

hi so I couldn't really find a solution to this, I recently got the aria 2 and every single time I step on the scales my body fat percentage changes, sometimes drastically and sometimes just a bit but I will step on the scales 10 times in a row, it will go from 21.8 to 21.1 to 21.6 etc and then the next day it will be 22.6, how do I fix this?

Hello @tvin17 and a warm welcome.  Every device we use to measure ourselves has measurement error.  Your small measurement differences are consistent with known error using bioimpedance devices.  Something like the difference between the 21.6 one day and the 22.6 the next day is commonly seen because of differences in your hydration level.

Your numbers are absolutely consistent with how this stuff works.
