I know I am supposed to be drinking 64oz of water per day but I'm wondering what counts towards this "water" number? Does the Vitamin Water Zero, Propel zero and Powerade Zero count towards the water intake? Do my protein shakes count? Or, does it have to be plain old water?

Yes, it counts. I specifically asked this with the nutritionist at Kaiser. All your liquids count.

ANY liquid counts as long as it's not caffeinated, caffeine is a diretic and dumps about as much liquid as you take it in.

Yes I was told that all liquids count toward your liquid intake, even the shakes. But I was also told that Vitamin water (any kind water with vitamins) ar not a good thing to take because of the fat soluble vitamins in them. You are taking supplemental vitamins with fat soluble vitamins in them and too much is not a good thing. I would avoid the vitamin containing waters.

Thanks Elise!! I didn't even think of that!! I will stay away from those but that strawberry guanabana is sure yummy!
