在一项旨在评估短期食物剥夺对认知功能影响的研究中，研究人员对女性受试者样本（N = 21）进行了三种程度的食物剥夺（在测试前24小时内不吃一顿饭、不吃两顿饭或不吃所有食物）和在测试前24小时正常饮食的情况下的认知功能测试。研究发现，食物剥夺对持续注意力、注意力集中、简单反应时间或即时记忆没有显著影响。然而，当受试者在测试前被剥夺食物24小时时，他们在低加工负荷叩击任务中的表现明显较差，而当他们在测试前未被剥夺食物时，心率明显较高。这些结果与之前发现的与自发节食行为相关的认知功能损伤（使用本质上相同的任务电池）形成鲜明对比。
In a study designed to assess the effects of short-term food deprivation on cognitive function, a sample of female subjects (N = 21) was tested on a number of measures of cognitive function after three levels of food deprivation (miss one meal, miss two meals or miss all food for 24 h prior to testing) and a condition in which they ate normally for 24 h prior to testing. There was found to be no significant effects of food deprivation on sustained attention, attentional focus, simple reaction time or immediate memory. However, performance on a low processing load tapping task was significantly poorer when the subjects were deprived of food for 24 h prior to testing, and heart rate was significantly higher when they were non-deprived. These results stand in contrast to the impairments in cognitive function previously found to be associated with spontaneous dieting behaviour (using essentially the same task battery).
