Transcript for Fast-Paced Movies, Television Shows May Lead to More Snacking
Calling all couch potatoes. If you are watching your waistline you may want to be aware of what you're watching in general. A new study showing how your favorite shows and movies could cause you to reach for the snack bowl. How do you know what you're doing? I don't. Reporter: They are the flicks that keep us on the edge of our seats and hanging on to every move. But could action-packed thri thrillers also be waistline killers? Talk to the hand. Reporter: A new study from Cornell university finding that compared to lower-paced movies fast-paced flips may lead to more snacking. Randomly assigning 100 stunts to watch "The island" as opposed to "Charlie rose" on public television. One after another they keep going to the darkness and don't return. Reporter: Those participants were given generous amounts of cookies, candies, grapes and it turns out the students who watched "The island" ate 140 more calories than the students who watched "Charlie rose." That's 65% more calories. Even watching an action film without sound still led people to eat 47% more calories compared to the talk show. Reporter: The theory, the viewers tend to be more distracted by fast-paced flicks leading to more mindless eating. Thanks for the advice. Hey, we're here for you. There are other studies that show cooking programs attract more unhealthy eating than nature shows and in general watching any sort of good TV increases the appetite. A little food for thought. So if you're snacking right now, we understand. Thank you. These ideas, it's incredible. I found the cooking one to be so -- I would be reaching -- I would think I'd be reaching -- in just the option. Is the weather action-packed?
