The study, published Monday in the Journal of the American Medical Association: Internal Medicine, looked at the effect of various movie genres on undergraduate students. 94 students were divided into three groups, each of which was shown 20 minutes of a movie or TV show. Those watching an action film consumed almost twice as much as those watching a talk show.
All three of the groups were offered M&Ms, cookies, carrots, and grapes while watching the TV. One group was shown the thriller The Island, one group was shown The Island on mute, and one group was shown a clip from Charlie Rose. The results were staggering: The students watching The Island consumed a total of 206.5 grams of food, while those watching Charlie Rose consumed a total of just 104.3 grams of food. Those watching the muted version of The Island still consumed more than the Charlie Rose viewers, with a total of 142.1 grams of food.
