“…In addition, the posterior parietal cortex and vlPFC exhibited stronger connectivity with the vmPFC during regulation, suggesting that these brain regions are involved in implementing changes in the decision-making circuitry during cognitive regulation [160]. Cognitive regulation therefore appears to affect decision-making through valuation regulation and behavioral control, where chronic stress may affect hedonic valuation but not cognitive regulation [161]. However, individuals with reward and cognitive deficits may be more prone to altered cognitive regulation, requiring increased frontoparietal functional connectivity [162].…”

Emotional eating is commonly defined as the tendency to (over)eat in response to emotion.Insofar as it involves the (over)consumption of high-calorie palatable foods, emotional eating is a maladaptive behavior that can lead to eating disorders, and ultimately to metabolic disorders and obesity. Emotional eating is associated with eating disorder subtypes and with Accepted manuscript / Final version abnormalities in emotion processing at a behavioral level. However, not enough is known about the neural pathways involved in both emotion processing and food intake. In this review, we provide an overview of recent neuroimaging studies, highlighting the brain correlates between emotions and eating behavior that may be involved in emotional eating.Interaction between neural and neuro-endocrine pathways (HPA axis) may be involved. In addition to behavioral interventions, there is a need for a holistic approach encompassing both neural and physiological levels to prevent emotional eating. Based on recent imaging, this review indicates that more attention should be paid to prefrontal areas, the insular and orbitofrontal cortices, and reward pathways, in addition to regions that play a major role in both the cognitive control of emotions and eating behavior. Identifying these brain regions could allow for neuromodulation interventions, including neurofeedback training, which deserves further investigation.

“…‘Increase’ condition) (e.g. Hutcherson et al ., 2012 ; Scharmüller et al ., 2012 ; Ferreira et al ., 2019 , 2021 ; Janet et al ., 2021 ). Outside the laboratory, similar reappraisal strategies could therefore prompt long-lasting changes in eating behaviour not only by restraining the desire for unhealthy foods but also by enhancing craving and motivating consumption towards healthier food options.…”

Growing evidence supports the effectiveness of cognitive reappraisal in down-regulating food desire. Still, the neural bases of food craving down-regulation via reappraisal, as well as their degree of overlap versus specificity compared with emotion down-regulation, remain unclear. We addressed this gap through activation likelihood estimation (ALE) meta-analyses of neuroimaging studies on the neural bases of (a) food craving down-regulation, and (b) emotion down-regulation, alongside conjunction and subtraction analyses among the resulting maps. Exploratory meta-analyses on activations related to food viewing compared with active regulation and up-regulation of food craving have also been performed. Food and emotion down-regulation via reappraisal consistently engaged overlapping activations in dorsolateral and ventrolateral prefrontal, posterior parietal, pre-supplementary motor, and lateral posterior temporal cortex, mainly in the left hemisphere. Its distinctive association with the right anterior/posterior insula and left inferior frontal gyrus suggests that food craving down-regulation entails a more extensive integration of interoceptive information about bodily states and greater inhibitory control over the appetitive urge towards food compared with emotion down-regulation. This evidence is suggestive of unique interoceptive and motivational components elicited by food craving reappraisal, associated with distinctive patterns of fronto-insular activity. These results might inform theoretical models of food craving regulation and prompt novel therapeutic interventions for obesity and eating disorders.

Chronic stress alters reward sensitivity and contributes to anhedonia. Chemosensation is dominated by a hedonic dimension, but little is known about the association between chronic perceived stress and hedonic chemosensation in non‐clinical populations. In the current study, 325 participants (201 females) completed a questionnaire‐based survey measuring their chronic perceived stress (Perceived Stress Scale; PSS), chemosensory pleasure (Chemosensory Pleasure Scale; CPS), and olfactory metacognitive abilities (odor awareness, affective impact of odor, importance of olfaction). For females, higher PSS scores significantly predicted lower CPS scores, which is mediated by the positive odor awareness. Moreover, negative odor awareness was identified as a moderator underlying the relationship between PSS and CPS scores in females but not in males. For females, higher PSS predicted lower CPS for those with lower, but not for those with higher levels of negative odor awareness. These results show that the link between chronic perceived stress and chemosensory anhedonia is pronounced in females, with olfactory perception playing a key role. The current study provides insights into the understanding of stress‐related anhedonia and into the development of effective treatments.
