I used another scale before where my FAT % was about 22%, then I got this Nokia scale and my % went down to 20-19%. I do exercise cardio/gym and I eat healtier so I'm expecting some results and the FAT % have go down to 17%. Then all of the sudden one morning I went from 17% to 9%. And now each morning I'm at 8% or slightly lower.
What could have happened?
