When you start working out and people often say something like “that’s just water weight”. What is that “water”?

It’s exactly what it sounds like. Your body is made mostly of water so things like how much you’ve been sweating and hydrating will cause your weight to fluctuate by a few pounds. Your electrolyte (salt) intake also has an impact on how much water your body will hold on to since your body wants to maintain a certain salt level. Eat more salt and your body retains some more water to keep your salt levels around the same amount (about 0.9%).This changes on a much faster basis than your body can gain muscle or lose fat.
