Do you think weight scales can be inaccurate or is it possible to lose most muscle?

[RyanEC]

Yesterday my body analysis scale said I was 177 lbs, 21% fat and 43% muscle.
Today it said I was 180, 27% fat and 20% muscle.
I have been working out more, eating less calories and have eating more protein in my diet so this doesn’t make sense.

Those machines are just a gimmick, so much can influence the readings they can fluctuate widely from reading to reading.
