How does it measure hydration?

It's shocking how much you eat when you aren't paying attention and keeping track.

You are so right about that!

I don't know how it measures hydration, but it's been pretty on the money with mine. If you're dehydrated, your fat % goes up. That alone is enough to keep me drinking water :)!!!

That's why I don't buy anything in boxes or bags.
