A new Cornell Food and Brand Lab study of 497 diners in 60 restaurants shows that diners who ordered their dinner from heavier wait staff were four times more likely to order dessert, and ordered 17% more alcohol.
“No one goes to a restaurant to start a diet. As a result, we are tremendously susceptible to cues that give us a license to order and eat what we want,” says Tim Doering, researcher at the Cornell Food and Brand Lab and lead author of the study. “A fun, happy, heavy waiter, might lead a diner to say ‘What the heck’ and to cut loose a little.”
The study, which is published in the current issue of the journal Environment and Behavior, observed 497 diners ordering dinner in casual American restaurants – like Applebee’s and TGI-Friday's. It then compared each customer's order and Body Mass Index (height and weight ratio) to the BMI of the person who waited on them. Interestingly, Doering notes, “A heavy waiter or waitress seems to have an even bigger influence on the skinniest diners.”
Along with the size of your waiter, the lighting, music, and even where you sit has been shown to unknowingly bias what you order. Although you can’t change your waiter or the music in a restaurant, you can follow a personal ordering rule-of-thumb: “Deciding that you’ll have either an appetizer or a dessert – but not both –before you get to the restaurant could be one of your best diet defenses,” suggests coauthor Brian Wansink, Ph.D., Director of the Cornell Food and Brand Lab and author of Slim by Design.
The study was self-funded by the Cornell Food and Brand Lab.
