“Feeling fat” is a subjective state that theoretically contributes to the maintenance of binge eating (BE). However, feeling fat, and its relation to BE among individuals with higher-weight bodies, has been infrequently studied. This study proposes a momentary-level model in which negative moral emotion states (disgust, guilt, shame) mediate the association between feeling fat and binge eating. In this study, 50 adults with higher-weight bodies (M_BMI=40.3 ± 8.5 kg/m²; 84% female) completed a two-week ecological momentary assessment protocol, which measured experiences of feeling fat, emotion states, and binge-eating behavior. Univariate generalized linear mixed models (GLMM) evaluated the momentary associations among levels of feeling fat at Time 1, emotion states at Time 2, and binge eating at Time 2, controlling for Time 1 emotion states. GLMM results suggest that increases in each emotion from Time 1 to Time 2 mediated the association between Time 1 feeling fat and Time 2 binge eating. When modeled simultaneously within one multivariate multilevel structured equation model, disgust appeared to drive the relation between feeling fat and binge eating, over and above guilt and shame. Although preliminary, findings suggest increases in negative moral emotions, particularly disgust, mediate the feeling fat-binge eating association in adults with higher-weight bodies.

“感觉肥胖”是一种主观状态，理论上有助于维持暴食（BE）。然而，对于体重较高的人来说，肥胖感及其与 BE 的关系却很少被研究。这项研究提出了一个瞬时模型，其中负面道德情绪状态（厌恶、内疚、羞耻）介导了肥胖感和暴饮暴食之间的关联。在这项研究中，50 名体重较高的成年人（M _BMI =40.3 ± 8.5 kg/m ²；84% 为女性）完成了为期两周的生态瞬时评估方案，该方案测量了肥胖感、情绪状态和暴饮暴食的体验。饮食行为。单变量广义线性混合模型 (GLMM) 评估了时间 1 的感觉脂肪水平、时间 2 的情绪状态和时间 2 的暴饮暴食之间的瞬时关联，并控制了时间 1 的情绪状态。GLMM 结果表明，从时间 1 到时间 2 的每种情绪的增加介导了时间 1 感觉肥胖与时间 2 暴饮暴食之间的关联。当在一个多元多级结构化方程模型中同时建模时，厌恶似乎比内疚和羞耻更能驱动感觉肥胖和暴饮暴食之间的关系。尽管是初步的，但研究结果表明，负面道德情绪（尤其是厌恶）的增加，介导了体重较高的成年人的暴饮暴食感觉。
