Bloody Marys, screwdrivers, and other mixed drinks pack a calorie punch, too. The alcohol alone is caloric: Vodka and rum both have 64 calories per ounce – and chances are you sneak in more than one shot's worth when mixing up cocktails at your buddy's makeshift bar. If you pair booze with sugary fruit juices or meal-in-a-glass Bloody Mary mixes, you're talking serious calories.
For a lighter cocktail that's super easy to make, Dulan suggests her Skinny Cape Cod. Just mix 6 ounces of zero-calorie lime-flavored sparkling water (choose a brand such as LaCroix that doesn't use artificial sweeteners) with 1 ounce cranberry juice and 1 ounce vodka. Or, treat the whole crew to Dulan's Skinny Sangria. The night before the game (or the morning of, if it's an afternoon or nighttime event), pour a bottle of red wine into a pitcher and drop in 2 cups of hulled, sliced strawberries. Cover and chill in the fridge for four or five hours. At the party, add in two 12-ounce cans of lime-flavored sparkling water and a few scoopfuls of ice. Pour the sangria into glasses and garnish with a few more fresh strawberries. The whole batch serves 10 tailgaters.
