Do you beleive in sportdrinks?

When You are exersicing your fatburning are going on. And to have a sprotdrink after is one way to provide your body with fast kalories. But how do the fatburning then respond. I for one think that sportdrinks are full of kalories and are no god for the fatburning. I think that suply your body with that is losing the reason for exersicing in the first place. I beleive that some water is the best way to have for quench one's thirst, and that is what you need to do after a god exersice. Not put in new kalories. I take a bottle of water, go home an prepare a god healthy meal.
