The game lasts four hours, but what you eat will stick with you way longer than that. By some (admittedly unscientific) estimates, Americans who snack on typical Super Bowl fare, like pizza, beer, soda, chips, dips, hot wings and nachos, could take in as many as 2,400 calories and 121 grams of fat just during the game. That’s more than most people should eat in a single day. In fact, you’d have to run an entire marathon to burn it off, says Sara Bleich, PhD, associate professor in health policy and management at Johns Hopkins School of Public Health. That’s assuming you’re 175 pounds and running a 15-minute mile, Bleich tells us.
