I don't remember where I actually
read this, but
water--good ol' water--was shown to actually have
negative calories. Apparently, it takes more
energy than the water contains for your body to properly
digest it, so you
burn a small amount of
fat or other
energy block. I believe the figure was -4 calories for an eight
ounce cup of the stuff. Neato, eh?
I suspect they just label
bottled water at zero calories to prevent a
mad rush of people
obsessed with their
weight from picking up crates of bottled water in the hopes of
drinking those extra
pounds away.
