Large Movie Popcorn with Butter: 1,220 Calories



A large "buttered" popcorn at the typical movie theater contains about 1,220 calories, San Francisco Chronicle restaurant critic Michael Bauer reminds us, quoting a decade-old survey: "You would have to swim 162 minutes to burn off that popcorn—longer than your average motion picture."

Not exactly what I want to read before a weekend in which I plan on finally seeing Star Trek (the IMAX version was sold out last week).

That reminds me, though, that it's cheaper and healthier to just sneak in a snack of my own. What snack(s) do you sneak in to the movies—and how?
