As portion sizes at many restaurants grow larger, so do our waistlines. Of course, no one says we have to finish that three-quarter pound burger or chug an entire Big Gulp. But what determines when we lay down the fork and push away from the table?
To find out, researchers led by Brian Wansink of the Cornell Food and Brand Lab served up some spaghetti. Some volunteers received a portion labeled “regular,” others got a dish described as “double size.” Although both plates contained the same amount of pasta, people ate more when they thought their serving size was normal. Participants who thought they’d gotten the piggy-sized portion left 10 times more food on their plates.
So if a big beverage were called, say, Double the Size of your Stomach, maybe we’d think twice about draining every last drop.
