i would say nay. if you're thirst after working out, drink water. what you need though, in some reasonable time frame, is nutrition - more than just carbs and electrolytes; protein.
i don't care for protein powder or shakes, but if you were to blend the coconut water with some quality whey, that would make more sense to me.
i would just wait an hour and make a proper meal. i'd be hungry by that point, too!
"dean ornish and dr. davis think the palmitic acid our bodies use for fuel while we sleep is poison if we eat it. zero-carbers like charles washington think the oldest fuel in our evolutionary history – glucose - used by organisms a billion years ago and without which the brains of modern mammals cannot survive for more than a few minutes – is an unnatural toxin if you eat it. both views ignore basic facts of medical physiology and defy evolutionary history." - kurt harris
