You might think it's a good idea to "save your calories" for the snacks in your future, but that'll only set you up to go overboard.
Pay attention to your calorie intake during the day, and give yourself a calorie budget for game-time snacking.
When you get there, just whip out your smartphone, and pull up a website like Calorie Count or CalorieKing to get an idea of the snack stats.
Whether the get-together is at your place or a pal's, there are plenty of smart ways to feed a craving for those classic game-day snacks.
