Metabolic Water

Metabolic water refers to water created inside a living organism through the metabolism, by oxidising energy-containing substances (protein and fat) in their food.

Humans obtain only about 8-10% of their water needs through metabolic water production.

In humans, the water produced from metabolism of protein roughly equals the amount needed to excrete the urea which is a byproduct of the metabolism of protein.

So it’s a zero sum gain, unless you filter and drink your piss. Camels we ain’t.
