When you grab a bite to eat somewhere, there are particular decisions you have to make. Obviously, what you’re going to eat but also what size you’re going to order. You may have noticed how the different sizes vary by each restaurant/fast food chain. What you may not have noticed is a small order at one place might be considered a medium at another. For example, you’re at Burger King and ask for a small order of fries because you want to be conscious of the amount you’re eating, but if you had gone to McDonald’s that same small order at Burger King would have been considered a medium. Would this make a difference in your decision making?
Aradhna Krishna, a marketing professor at the University of Michigan, has performed studies over this labeling phenomena. What she found is that food sizes have become larger over time. “So, that same hamburger has become bigger, the french fries have become bigger, and again this is leading to obesity,” said Krishna on NPR.
Krishna wanted to learn if the label was truly making a difference in what size consumers bought. In order to do so, she conducted an experiment where she offered participants a cookie. One was given a label as “medium” and the other was given a label as “large.” The catch was that both were actually the exact same size. The results proved the theory and showed that more people chose the “medium” cookie over the large.
“Just because there’s a different size label attached to the same actual quantity of food, people eat more. But also, think they’ve not eaten as much,” said Krishna. “Sizes should be more uniform and that will only help the consumer because you’ll know what you’re getting.”
According to the Centers for Disease Control and Prevention, a “large” soda today is six times bigger than a “large” soda in the 1950s. Past studies have also shown that by eating off a smaller plate, people can sometimes overestimate the serving size they’ve been given, and drinking beer from a glass that’s straight as opposed to one that’s curvy can help people keep better track of how much they’ve drank.
