Ofc usualyl that'd kill you, you'll need some electrolytes on top of that. Now lets say 12x25 Kcal. that is 300 Kcal of water a day. Now add on top of that that you'd have to heat the water to body temperature, or alot of the Kcal you gained by the water would be literalyl burned away from your body heating the Water up.
Is it possible to live off of 300 kcal a day? I doubt so.
