So, I have been playing with my scale a bit. Just now, I could get a 3lb fluctuation on my scale by simply adjusting where my feet were. I know that for a lot of people 3lbs isn't that much, but when I got on the scale yesterday, it read 271.4. And while indeed I did have a high sodium day the day before, I found 6lbs of water retention to be a little crazy. Not impossible granted, but doubtfully high. Yesterday was another high sodium day, inadvertently, so my scale is still bouncing around between 268.8-271.4 depending on how I stand on it. I could get any of the numbers multiple times in a row, if I stood on the scale the same way.
So here's my question, is it normal that how you stand on a scale alters the weight being displayed? Or should I consider getting a new scale?
