The diners eating from the regular bowls consumed an average of nine ounces per person, about the equivalent of a regular can of soup. Diners eating from the bottomless bowls wolfed down at least twice as much, some devouring more than a quart.
The study stops at this point, but we assume that these patrons didn't actually stop eating until soup was pouring so readily from every one of their orifices that no more could be forced in, at which point the researchers giggled and prepared to upload a video to YouTube.
Yeah, yeah, we know, we can hear you now: "Holy smokes! You mean that sitting nearly motionless for hours on end isn't very good for me?! Be sure to let me know when you work out the whole 'water wet, sky blue' thing, assholes." It's more complicated than that. So quit it with the sass.
There are these neat little communiques between your stomach and your brain called "orosensory signals of satiation." They're the signals your stomach sends off when it's full to let the brain know when it's time to stop shovelling Cheetos down.
Unfortunately, orosensory signals are like anemic little schoolgirls when pitted against all the other things that constantly vie for your brain's attention, and have a nasty habit of getting shoved aside by bigger, stronger signals. Distracting signals like these clog up your brain all the time when you're doing something fun, like surfing the net.
Imagine that the cameraman is your brain. Your stomach is the guy with his hands in the air.
So you're sitting there, eating chips with one hand and moving the mouse with the other. Have you had four handfuls, or five? How full was the bag when you started? Don't ask your stomach, it's retarded. And your brain is too busy handling the sensory information provided by that .gif of the dramatic hamster to care.
So that pretty much leaves... well, no one. According to a study from the American Journal of Clinical Nutrition, the damage works out to eating about fifteen percent more of your snack while distracted. You might as well have a monitor that fires little sausages into your mouth.
Uh, we're going to have to stop now. We have a patent application to fill out.
