Action films may get the heart racing, but they could also expand your waistline, a new study suggests. Previous research has shown that people tend to eat more if they are watching television. But scientists from Cornell University wanted to know whether the type of programming made a difference. To find out, they gave snacks to 97 undergraduate students and split them into three groups. The first group watched a loud, frenetic clip from “The Island,” a 2005 action movie directed by Michael Bay. The second watched part of a Charlie Rose interview program on PBS. The third group watched the same excerpt from “The Island” as the first group, but without sound. The first group consumed the most by far — 65 percent more calories than the “Charlie Rose” group (354 calories versus 215) and 98 percent more food (7.3 ounces versus 3.7). The group that watched “The Island” on mute ate 46 percent more calories (315) and 36 percent more food (five ounces) than the Rose group. Aner Tal, a research associate at Cornell’s Food and Brand Lab and the study’s lead author, said the first “Island” group consumed so much more food relative to calories than the second group because “they enhanced their consumption of baby carrots more than the others — those weigh a lot and contain few calories.” The researchers, whose work appears in JAMA Internal Medicine, are now working on a follow-up study asking why the action film caused people to eat more. But Dr. Tal says he thinks pacing may be key. “We choose this particular movie for its pacing, because it had a lot of camera cuts,” he said. “It could be that the camera cuts and sound set the tempo for the pace at which people eat.”
