Your weight will actually fluctuate a few pounds throughout the day, depending on if you've eaten or drank anything...or pooped.Okay, I'm sorry, but....
What. The ****. Is with. Weight scales?!
Seriously. One point, I'm 130 pounds. Suddenly, I'm 127. What the ****????
This wouldn't be annoying if I wasn't trying to lose weight!
if the scale is giving different readings in a few seconds then it could just be how you're standing on it and whether or not its on a completely level surface. The ones that spin actually get knocked out of calibration pretty easily.
