The Average Nationals Fan Will Gain Over 10 lbs Throughout The 2026 Season According To A New Study

The Washington Nationals are set to host their opening weekend at Nationals Park starting on Friday, April 4th, against the defending champions, the L.A. Dodgers!

Now, as Nationals fans are ramping up for another 162-game season, there’s one more thing that comes with the season that they may not realize: some pretty significant weight gain!

According to a recent study, the average Washington Nationals fan will pack on around 10.4 lbs of weight throughout the season – a metric that was calculated based on data collected via survey and known data about dining at the ballpark!

Why do Washington Nationals fans gain weight during the season?

The study had several interesting findings, notably that the average baseball fan eats roughly 753 more calories on gameday than on regular days.

Combined with an average of 3.2 games being watched per week, that means that the average baseball fan could gain as much as 18 lbs over the course of a season!

Among Nationals fans, based on survey responses, the average fan watches around 2.9 games per week throughout the season and eats an additional 490 calories per game day, which means the typical Nationals fan could gain as much as 10.4 lbs by the end of the season!
