Drink water between light beers.
"Men tend to take in a huge amount of calories at tailgate parties from beer alone," Dulan says. "A lot of guys don't realize that a six-pack contains 900 calories. You'd need a 90-minute treadmill session to burn that off." To guzzle fewer calories, always go with light beer, Dulan says. Even if you're more of an IPA guy than a Miller Lite fan, remember: You're in a parking lot; you might as well save the good stuff for happy hour. But if you just have to have your favorite full-bodied craft brew, keep it to only one or two. Regardless, Dulan recommends drinking water between beers to keep you hydrated – and to keep you from reaching for the next one too soon.
