The Light = Healthy Intuition. Yi Li  Nico Heuvinck  Mario Pandelaere. Journal of Consumer Psychology, May 2 2021. https://doi.org/10.1002/jcpy.1249

Abstract: This research documents a “light = healthy” intuition, such that consumers perceive foods that weigh less are healthier than their heavier counterparts with the same serving size. Subsequently, consumers consume a larger quantity of lighter‐weight foods. The intuition is based on a co‐activation of two meanings of the word “light”: light in physical weight and light in calorie content. An implicit attitude test finds support for this association between physical weight and food healthiness. Two studies show that physically lighter foods are perceived to be healthier because they are assumed to contain fewer calories. In line with the proposed co‐activation mechanism, the intuition is bi‐directional, where consumers also expect healthier foods to weigh less. Consequently, they discredit health claims issued for heavier foods. Finally, it was found that activating a competing intuition is effective at debiasing the “light = healthy” intuition.
