Answer 1

“Water weight” is simply the weight of water in your body.

Water is stored and used in your body, but it’s way easier to get out than energy stored as fat, or the weight of your body tissues. You can take a diuretic, or just sweat, and you lose the weight of water. (This is often not healthy, because dehydration can do a lot of bad things to a lot of systems.)
