"Smile away your cravings" - Facial feedback modulates cue-induced food cravings. Appetite. 2017 May 23;: Authors: Schmidt J, Martin A Abstract Food cravings are common experiences that precede dysfunctional eating behaviors, such as overeating and binge eating. These cravings are often related to negative affect, especially in emotional eaters. Recent studies have revived interest in a theory on the implicit modulation of affect: the facial feedback-hypothesis. This theory claims that mimic expressions influence affective experiences. Given the association between negative affect and food craving, facial feedback could provide a means to reduce or prevent food cravings. In an experimental study, using a read aloud task, we examined, whether an implicit modulation of facial muscle activity - zygomatic muscle (smiling: FF+) and corrugator muscle (frowning: FF-) - would alter food cue-induced cravings in healthy young women (n = 60). We further examined, if traits in emotional eating influence the facial feedback-effect. The activation of the zygomatic muscle prevented the occurrence of food cravings after exposure with palatable food cues. Food craving only increased in the FF- group (p = 0.029). The facial feedback effect was especially pronounced in emotional eaters, indicated by a significant moderation (p = 0.041). In participants with high degrees of emotional eating, food craving was reduced in the FF + group and amp...
