Vanderbilt marketing professor Kelly Haws calls her latest research “Justifying by Healthifying,” in the journal Appetite.
“So, one could argue that good advice for someone trying to manage their food intake would be not to clean their plate.”.
Professor of Marketing at Vanderbilt University’s Owen Graduate School of Management, studies consumer behavior, with a particular focus on food consumption behaviors and food decision-making.
Study participants were served individual plates of cookies with a varying number of cookies on each plate, and instructed to eat three cookies.
We’re more likely to give ourselves permission to overeat by telling ourselves that it’s not as unhealthy as it may actually be.
As in the previous experiment, participants were more tempted to eat just one more when there was only one left.
“However, providing another mechanism for consumption closure, such a doggy bag, dampens the effect of wanting to eat more,” Haws said. »
