Abstract
Consumers tend to eat more food in larger portions than in smaller portions. Here, we suggest that it is possible to reduce this so-called “portion size effect” with mental imagery. We conducted two online studies: The first study showed that participants with higher scores of mental imagery selected a smaller percentage of food from the largest portion, than from the smaller portions. The second study revealed that when participants were explicitly asked to imagine the sensory experience of eating, the percentage of food selected was also lower when the food was selected in the large portion, than in the medium portion, thus reducing the portion size-effect.
