Many higher-weight individuals have internalised societal weight stigma, devaluing themselves because of their weight. Rejecting and challenging societal devaluation is generally associated with superior outcomes compared with stigma internalisation or inaction; however, stigma resistance has not been studied in higher-weight individuals, despite ubiquitous weight stigma in daily life. Applying a social identity framework, we utilised decision tree analysis to explore predictors of responses to weight stigma in 931 self-classified higher-weight individuals. While ingroup identification with the group ‘Fat’ was the major predictor of stigma resistance (versus internalisation), perceived illegitimacy of societal weight stigma defined a subgroup of resisters even in the absence of group identity. Interventions focusing on the illegitimacy of unequal social status and treatment may be effective at reducing internalisation and fostering resistance in a population with characteristically low ingroup identity.

许多体重较高的人已经内化了社会的体重耻辱，因为他们的体重而贬低自己。与污名内化或不作为相比，拒绝和挑战社会贬值通常与更好的结果相关；然而，尽管日常生活中普遍存在体重耻辱感，但尚未在体重较高的个体中研究抗耻辱感。应用社会认同框架，我们利用决策树分析来探索 931 名自我分类的高体重个体对体重耻辱反应的预测因子。虽然对“肥胖”群体的内群体认同是污名抵抗（相对于内化）的主要预测因素，但即使在没有群体认同的情况下，对社会重量污名的感知非法性也定义了一个抵抗者亚群。
