Gatorade is a horrible way to stay hydrated. The only time Gatorade is helpful is when you need electrolytes, and the only time you need the amount of electrolytes that Gatorade has to offer is after you have been sweating profusely for 30 minutes or more. The amount of sugar in a Gatorade is extremely high, so if you do drink it, drink it wisely, unless you have a crazy high metabolism naturally, then it doesn't really matter what you drink.
