      Hmm let’s see. For easy math, let’s assume a large person who is 100kg.

      That means they have 80kg of water in them. Drinking 10kg of water would put them at 90kg of water, but also increase their body weight by 10kg. Thus they are 90/110*100=81.81% water.

      It seems one would get diminishing returns on this too. You might be right. I’m interested know what the proper steps to figure this out is.

        100kg person is 80kg water -> 20kg not water

        For them to be 90% water -> 20kg not water of a total of 200kg -> 180kg water

        180kg water after drinking - 80kg water before drinking = 100kg water must be consumed
