Can Your Ears Help Control Your Stomach? According to a recent study, it looks like the answer is yes:
In one paper, marketing professors at Brigham Young and Colorado State universities asked 71 volunteers to eat a snack of pretzels while wearing over-the-ear headphones. Some volunteers were subjected to loud white noise from the headsets as they ate, while a second group heard quieter noise.
The result? Those listening to the loud noise consumed 49% more pretzels than those listening to the quieter noise. The findings suggest, according to the researchers, that the sound you make while eating is an important cue to how much you’re taking in. Listening to loud noise evidently made it harder to know when to stop, implying that dieters might want to turn down the music while dining.
Interestingly, the paper was the work of marketing professors. No doubt the findings will be used by restaurant owners to crank up the volume even higher.
