饮食限制量表预测暴食症发病的发现被解释为表明节食会导致这种饮食失调，尽管缺乏证据表明这些量表是饮食限制的有效措施。作者进行了四项研究，测试饮食限制量表是否与不显眼地测量的热量摄入量呈负相关。这些研究的食物消耗、环境和人群各不相同，表明常见的饮食限制量表在很大程度上与急性热量摄入无关。结果表明，这些量表并不是短期饮食限制的有效衡量标准，并意味着重新解释使用这些量表的研究结果可能是谨慎的，包括那些表明饮食限制是贪食症病理学危险因素的研究结果。
The finding that dietary restraint scales predict onset of bulimic pathology has been interpreted as suggesting that dieting causes this eating disturbance, despite the dearth of evidence that these scales are valid measures of dietary restriction. The authors conducted 4 studies that tested whether dietary restraint scales were inversely correlated with unobtrusively measured caloric intake. These studies, which varied in foods consumed, settings, and populations, indicated that common dietary restraint scales were largely uncorrelated with acute caloric intake. Results suggest that these scales are not valid measures of short-term dietary restriction and imply that it may be prudent to reinterpret findings from studies that use these scales, including those that suggest dietary restraint is a risk factor for bulimic pathology.
