Although the majority of adults will attempt to lose weight at some point in their lives, most weight loss behaviors are ineffective and potentially harmful. Further, weight loss behaviors often closely resemble disordered eating, and include behaviors such as fasting and purging. The current study examined potential predictors of disordered approaches to weight loss in the context of same-sex and opposite-sex romantic partnerships by investigating participants' (n = 500, M_age = 29.62 years) BMI, body image, self-esteem, relationship quality and disordered weight loss behaviors. We conducted analyses using Actor Partner Interdependence Models, which revealed that the greatest predictors of participating in disordered weight loss behavior were body dissatisfaction and having a male partner. These findings suggest that it is not sexuality, per se, that places individuals at risk for disordered weight loss behavior, but perhaps the value placed on thinness as defined by particular gender and cultural groups.

尽管大多数成年人会在生活中的某个时刻尝试减肥，但大多数减肥行为无效且可能有害。此外，减肥行为通常与饮食失调非常相似，包括禁食和排便等行为。目前的研究检查的紊乱的方法潜在预测到的体重减轻的同性和异性浪漫伙伴关系的上下文通过调查参与者（Ñ  = 500，中号_年龄 = 29.62岁）的BMI，身体形象，自尊，关系质量和失重的减肥行为。我们使用演员伴侣相互依赖性模型进行了分析，结果表明参与失调的减肥行为的最大预测因素是身体不满意和有男性伴侣。这些发现表明，性行为本身并没有使个人面临失调的减肥行为的风险，而是某些性别和文化群体所定义的瘦身价值。
