要成为一个成功的节食者，一个人必须能够始终如一地抵制眼前的诱惑，以实现更大的，但延迟的减肥回报，增加吸引力和更好的健康。这些长期利益绝不能保证，因为延迟回报比即时回报更不确定。一些研究人员认为，节制饮食者的群体由两个群体组成：不成功的节食者在节制方面得分高，在去抑制方面得分高;成功的节食者在节制方面得分高，但在去抑制方面得分低。本研究探讨在何种程度上限制饮食结合自我控制的个体差异（类似于低去抑制）与成功决策的任务，模仿节食的不确定性（测量与爱荷华州赌博任务）。正如预期的那样，自我控制缓和了克制和决策之间的关联：当自我控制力低时，克制饮食与更糟糕的决策有关，但当自我控制力高时，则与更好的决策有关。这表明，那些高度克制和高度自我控制的人可能在节食尝试中更成功，因为他们通常更善于抑制短期奖励，以获得更好的长期结果。(C)2008爱思唯尔有限公司版权所有。
To be a successful dieter, one has to be able to consistently resist immediate temptations in order to achieve the bigger, but delayed rewards of weight loss, increased attractiveness and better health. These long-term benefits are by no means guaranteed as the delayed rewards are more uncertain than the immediate rewards. Several researchers have suggested that the Population of restrained eaters consists of two populations: unsuccessful dieters who score high on restraint and high on disinhibition, and successful dieters who score high on restraint but low on disinhibition. The present study examines to what extent restrained eating in combination with individual differences in self-control (akin to low disinhibition) is related to successful decision making on a task that mimics the uncertainty of dieting (measured with the Iowa Gambling Task). As expected, self-control moderated the association between restraint and decision making: restrained eating was related to worse decision making when self-control was low, but to better decision making when self-control was high. This suggest that those high in restraint and high in self-control may be more successful in their dieting attempts because they are generally better at inhibiting short-term rewards in order to gain better long-term outcomes.
