I don't believe it is either especially if you are an athlete which I am. However the recommended 8 glass of water a day is absolutely unnecessary for raw paleos and stressful on your kidneys, at most we need 2 glasses. When you see wild animals drinking water its a couple gulps and they are gone. They don't drink 8+ glasses worth.
I disagree. Wild carnivores are seen drinking a lot of water from streams. In my own case, my own water-intake varies considerably from drinking no water by itself just depending on raw fruit to drinking 2 litres of mineral water in 1 day. Plus,RZCers most likely have to drink more water than the rest of us.
