Many of us were raised with mentality of “cleaning” our plate at the end of the meal; basically, it means finishing all the food on your plate. Some researchers wondered if this leads to unhealthy overconsumption of food, and indeed it does. There’s some simple things you can do to avoid eating too much like making smaller servings, not finishing everything just because it’s on your plate, and you can just use smaller plates.
“Many of us were raised with this ‘clean your plate’ mentality, stemming from a desire to ensure one is not being wasteful or their children are eating well; however, this can also lead to overconsumption,” Haws said. “So, one could argue that good advice for someone trying to manage their food intake would be not to clean their plate.”
Haws and her co-authors were interested in exploring how the clean-plate phenomenon, called “consumption closure,” affects our desire to keep eating more than we should or want to when there’s just a small amount left, “The questions we had were: Is there something special about having this small quantity left over, and what processes do people use when justifying continued consumption or deciding whether or not to continue consuming?”
