Sports drinks are just fine to guzzle, especially during the summer time when you're sweating a lot.
They are loaded with electrolytes that can replace the ones you lose during a bout of profuse sweating, plus they taste great. However, most are loaded with sugar.... which releases insulin, signaling your body to store, store, store! Of course you don't want that.
It would be better to start burning calories from the glycogen or fat reserves already in your body, rather than having to start off by burning off what you just drank simply because you were thirsty.
A better choice of hydration would be a sugar-free workout beverage (Gatorade and Powerade both make good low calorie, high electrolyte drinks that are sold at most gas stations around here), or....wait for it.... plain ole water.
