(sorry to revive a thread from October ...)
Yes, I too drink the Coconut Water (not milk). It’s very refreshing before & after WODs and it has much, much less sugar than sports drinks. It seems to give you a good boost of energy.
I’m reading about Zone myself and was curious to see how to factor in drinks such as these. I do not yet have “Enter the Zone” but it seems I will need to pick up a copy - because there are 12 grams of sugar in a 14 OZ bottle of the Zico brand, and so a conversion to blocks is necessary.
There are also 569mg of Potassium & 160mg of Salt. Zero fat, Zero Protein in one 14 oz bottle.
