Abstract
Disgust-based body image concerns can bias autobiographical memory towards the recall and avoidant processing of disgust-related memories of the own body. Repeated exposure to such memories may help breaking avoidance and promote the habituation of disgust, thereby lowering body concerns. Using a pre-post within-participant experimental design, we tested if repeatedly exposing women with high self-disgust (N = 61) to disgust-focused body memories vs. neutral memories led to changes in disgust, body acceptance, and reactive avoidance. Contrary to expectations, state disgust towards the body itself only decreased following exposure to neutral memories. Yet, disgust elicited by body-related memories decreased following both repeated exposure to neutral and body memories. Although acceptance was not found to significantly change in either exposure session, pre-post decreases in state disgust were associated with increases in acceptance following the disgust-focused exposure. In contrast to expectations, reactive avoidance increased from pre to post in the disgust-focused exposure. Overall, the results indicate that repeated exposure to disgust-focused body memories may help reduce disgust elicited by these memories and promote body acceptance. Yet, the effect of this repeated exposure to body memories did not extend to changing state disgust towards the body, possibly due to reactive avoidance.

Abstract
Disgust sensitivity refers to how unpleasant a disgusting experience is to an individual and is involved in the development of many psychiatric conditions. Given its link with food ingestion, there is an interest in understanding how an individual's susceptibility to disgust relates to dietary habits. One possible mechanism giving rise to this association is through the effects negative emotions have on high-order cognitive processes, but few studies take this model into account. The aim of this study was to characterize general disgust sensitivity in a clinical binge eating disorder (BED) population, and explore whether disgust sensitivity relates to inhibitory control and eating pathology. Following a case-controlled study design, our results show that: (1) disgust sensitivity and its subscales do not differ between BED and healthy controls, (2) higher disgust sensitivity in BED relates to greater behavioural inhibition, (3) inhibitory control reaction times relate to aspects of eating pathology, and (4) inhibitory control does not mediate relationships between disgust sensitivity and BMI among participants with BED. Understanding the role of disgust sensitivity in BED may allow us to understand how negative emotion systems maintain dysregulated eating behaviours with the potential to inform emotion-regulation treatment approaches. Level of evidence: Level III: Evidence obtained from well-designed cohort or case-control analytic studies.

Abstract
Individuals with an eating disorder (ED) often report to be disgusted by their body. Body-related self-disgust could play an important role in the development and maintenance of EDs. We investigated if women with relatively high ED symptom scores indeed respond with disgust upon exposure to their body as indexed by facial electromyography (fEMG) of the m. levator labii superioris and self-report. Given that one's self-disgust may increase/decrease depending on the relative distance of the own body to the thin ideal, we also assessed women's disgust for overweight- and thin-morphs of their body. Female undergraduate students (N = 104) were photographed and presented with their (morphed) body pictures, next to disgust-relevant and overweight body control pictures. Higher levels of ED symptoms were associated with stronger self-reported disgust to unedited body-pictures and overweight-morphs. Disgust to thin-morphs was unrelated to ED symptoms. Participants generally showed heightened facial disgust towards overweight morphs, yet the strength of facial disgust was unrelated to ED symptoms. Thus, the findings provide evidence for the involvement of heightened body-related self-disgust in ED symptomatology, albeit only on the basis of self-report.

Abstract
Feelings of disgust toward meat have been researched for at least 30 years, but so far the causal relationship that may link meat disgust and meat consumption has remained elusive. Two possible pathways have been proposed in previous literature: the more common pathway seems to be that meat disgust is developed after a transition to vegetarianism, potentially via the process of moralization and recruitment of (moral) disgust. Other accounts suggest the existence of a second pathway in which disgust initiates the avoidance of meat and this can be explained by existing theories of disgust functioning as a pathogen avoidance mechanism and meat serving as a pathogen cue. However, the evidence base for either relationship remains thin and to our knowledge no research has examined whether temporary meat abstention can lead to increases in meat disgust, as the first pathway suggests. We measured meat disgust and meat intake in n = 40 meat eaters before and after attempting a meat-free diet for 1 month (while taking part in the annual vegan campaign Veganuary). Although most participants lapsed to eating meat during this period, we found that reductions in meat intake during the month were predictive of increases in meat disgust afterwards. This supports the view that meat disgust is expressed as a result of meat avoidance in meat eaters. Implications for theoretical understanding of the relationship between meat disgust and meat avoidance, as well as the development of disgust based interventions are discussed.

Abstract
Facial emotion recognition (FER) is extensively investigated in psychological sciences in healthy individuals and clinical conditions. In this paper, we analyzed those studies in which FER was assessed in the case of obesity or fibromyalgia, in relation to the levels of alexithymia. Crucially, these two conditions frequently co-occur; however, no study has explored FER considering both fibromyalgia and obesity. Studies were identified using the electronic search engine of PubMed. The last research was run on 23 July 2021. Two independent lists were generated for the two clinical conditions. Six records were reviewed about obesity, while three records about fibromyalgia. The evidence relative to FER in obesity was not conclusive, whereas the evidence about an altered FER in fibromyalgia seemed more straightforward. Moreover, the role of alexithymia on FER in these clinical conditions was not extensively investigated. In our discussion, we highlighted those factors that should be carefully addressed in investigating FER in these clinical conditions. Moreover, we underlined methodological criticisms that should be overcome in future research.

Abstract
Disgust is an emotion that drives food avoidance. People vary in their responses to disgust, which is captured by their disgust sensitivity. Disgust sensitivity is clinically significant because it can influence eating behaviors, and indirectly people's body mass index (BMI). Inhibitory control can also influence BMI through the role that such reflective abilities play in governing food intake. In this study, we relied on neural models of disgust to suggest that disgust and inhibitory control are intertwined, and that inhibitory control facilitates the translation of disgust sensitivity into BMI. Mediation analyses applied to 46 subjects, including 29 normal body weight [BMI = 18.34 kg/m2 (SD = 1.58)] and 17 overweight/obese [BMI = 26.03 kg/m2 (SD = 2.58)] subjects, were used to test the hypothesis. Subjects completed the Chinese version of the Disgust Scale-Revised, and an inhibition control test (Food-Specific Stop-Signal Task). There were negative correlations between the disgust sensitivity score (DS) and body mass index (BMI), and between DS and stop-signal reaction time (SSRT). Moreover, BMI was positively correlated with SSRT. The mediation model results showed that disgust sensitivity was associated with BMI and that this relationship was mediated via inhibition control. There was no significant effect of DS on BMI, while the effect of SSRT on BMI was significant. This suggested that the effect of disgust sensitivity on BMI was fully mediated through food-specific inhibitory control. This supports our hypothesis that BMI is affected by disgust sensitivity and that this relationship is mediated by inhibition control. These findings reveal a key mechanism that underlies disgust sensitivity-BMI association and point to future research and potential interventions aimed at food intake management.

Abstract
Fear and disgust are distinct emotions that have been independently linked with EDs and may motivate avoidance behaviors that may be relevant targets for ED interventions (e.g., food rejection). Despite similar motivational function, it is possible that one emotion is more strongly associated with ED symptoms, relative to the other. Given that emerging evidence suggests that disgust-based behavior may be more difficult to change than fear-based behaviors, research is needed to evaluate whether each emotion differentially relates to ED symptoms. Therefore, the current study tested the relative importance of fear and disgust in accounting for variance in ED symptoms. Participants included undergraduate men (n = 127) and women (n = 263) from a university in the northeast US. Participants completed self-report measures assessing demographics, disordered eating attitudes and behaviors, and visual analog scales assessing fear and disgust responses to high-calorie food images, low-calorie food images, and non-food fear and disgust images. Bivariate correlations revealed significant positive associations among fear, disgust, and EDE-Q global symptom scores. Relative weights analysis results yielded relative importance weights that suggested disgust responding to high calorie food images accounts for the greatest total variance in EDE-Q global symptom scores in men, and fear responding to high calorie food images accounts for the greatest total variance in EDE-Q scores in women. Findings provide initial evidence that investigative and clinical efforts should consider fear and disgust as unique facets of negative affect with different patterns of relative importance to ED symptoms in undergraduate men and women.

Abstract
BACKGROUND AND OBJECTIVES Covariation bias refers to the phenomenon of overestimating the contingency between certain stimuli and negative outcomes, which is considered as a heuristic playing a role in the maintenance of certain types of psychopathology. In the present study, covariation bias was investigated within the context of eating pathology. METHODS In a sample of 148 adolescents (101 girls, 47 boys; mean age 15.3 years), a priori and a posteriori contingencies were measured between words referring to control and loss of control over eating behavior, on the one hand, and fear, disgust, positive and neutral outcomes, on the other hand. RESULTS Results indicated that all adolescents displayed an a priori covariation bias reflecting an overestimation of the contingency of words referring to loss of control over eating behavior and fear- and disgust-relevant outcomes, while words referring to control over eating behavior were more often associated with positive and neutral outcomes. This bias was unrelated to level of eating disorder symptoms. In the case of a posteriori contingency estimates no overall bias could be observed, but some evidence was found indicating that girls with higher levels of eating disorder symptoms displayed a stronger covariation bias. CONCLUSION These findings provide further support for the notion that covariation bias is involved in eating pathology, and also demonstrate that this type of cognitive distortion is already present in adolescents.

Abstract
Disgust is a core emotion that serves to protect one from engaging in activities that promote contamination and contracting disease. Since disgust is intimately connected to ingesting food, disgust sensitivity is probably also associated with dietary habits. The aim of the present study was to examine the relationship between obesity and disgust and between restraint and disgust. Participants (n=135, all female) were recruited and tested via the Internet. They indicated their desire to eat high-calorie foods and filled out several questionnaires assessing restrained eating and disgust sensitivity. We hypothesized that more restrained eaters would show increased disgust and that women with a higher BMI would show decreased disgust, which is what we found; that is, more restrained eaters showed increased core disgust and contamination disgust, whereas women with a higher BMI showed decreased core disgust and contamination disgust. Hence, feeling disgusted by food may be a strategy to uphold restraint, whereas relatively decreased disgust could encourage overeating.

Abstract
Covariation bias refers to the phenomenon of overestimating the contingency between certain stimuli and negative outcomes, which is considered as a heuristic playing a role in the maintenance of certain types of psychopathology. In the present study, an attempt was made to investigate covariation bias within the context of eating pathology. In a sample of 61 female undergraduates, a priori and a posteriori contingencies were measured between pictures of obese and slim bodies, on the one hand, and fear- or disgust-relevant outcomes, on the other hand. Results indicated that participants in general displayed an a priori and an a posteriori covariation bias reflecting an overestimation of the link between obese bodies and disgust-relevant outcomes. However, this bias was not related to eating disorder symptomatology. Meanwhile, eating pathology was positively associated with a priori covariation biases referring to the associations between obese bodies and fear-relevant outcomes, and between slim bodies and disgust-relevant outcomes. All in all, these findings suggest that covariation bias plays a role in eating pathology.

Abstract
In order to further explore the relationship between disgust sensitivity and eating disorder symptoms, 2 studies were carried out. In the first study, 352 higher education students (166 women, 186 men) completed a set of questionnaires measuring various aspects of disgust sensitivity and eating disorder symptoms. A correlational analysis revealed that there were few significant correlations between disgust scales and eating pathology scores. One exception was the relation between disgust sensitivity and external eating behavior, although this link only emerged in women. To investigate this relationship in more detail, Study 2 confronted women high (n=29) and low (n=30) on external eating behavior with a series of disgusting and neutral pictures. It was hypothesized that women who scored high on external eating would display shorter viewing times of disgusting pictures (i.e., show more avoidance behavior) than women scoring low on external eating. However, this hypothesis was not confirmed by the data. Altogether, the results of these studies suggest that there seems to be no convincing relationship between disgust sensitivity and eating disorder symptomatology, thereby casting doubts on the role of this individual difference factor in the development of eating pathology.
