BMI reading from Monitor vs. standard calculation.
Recently had myself measured and logged and from a reportedly accurate electronic BMI device it reported 22.2 which would seem to be a relatively good level, especially since my prior measurement (~6 months ago) reported 26.5
However, online calculators that simply consider height and weight in their calculation is reporting a 25.4
For obvious reasons I would like to believe the device version of my BMI. Can someone explain why the difference? Bone density maybe? Muscle vs fat % ? or simply an unreliable measurement?
From what I can find, the BMI calculation is a pretty straight forward math formula so there must be other factors that are being taken into consideration by the electronic device?
