关于食物的侵入性想法可能在不健康的饮食行为中发挥作用。与食物有关的想法会引起注意力的渴望和进一步的侵入性想法（Kavanagh，Andrade，& May，2005）。我们测试了将注意力转移到心理图像或身体感觉是否会减少对零食的侵入性想法的发生率。在两个实验中，参与者在三个10分钟的时间内报告了他们对探测器的想法。在基线和任务后阶段，参与者被要求让他们的思想漫游。在中间，实验，期间，参与者遵循走神（控制），思想转移，或思想抑制指示。与基线相比，自我导向或引导的图像，基于正念的身体扫描和思想抑制都减少了关于食物的想法的比例。在身体扫描和思维抑制之后，食物思维回到了任务后的基线频率，而不是反弹。虽然总体而言，渴望和思想频率是相关的，但干预措施对渴望没有影响。思维控制任务可以帮助人们忽略关于食物的想法，从而减少他们吃零食的诱惑。
Intrusive thoughts about food may play a role in unhealthy eating behaviours. Food-related thoughts that capture attention can lead to craving and further intrusive thoughts (Kavanagh, Andrade, & May, 2005). We tested whether diverting attention to mental images or bodily sensations would reduce the incidence of intrusive thoughts about snack foods. In two experiments, participants reported their thoughts in response to probes during three 10min periods. In the Baseline and Post-task period, participants were asked to let their mind wander. In the middle, Experimental, period, participants followed mind wandering (Control), thought diversion, or Thought Suppression instructions. Self-directed or Guided Imagery, Mindfulness-based Body Scanning, and Thought Suppression all reduced the proportion of thoughts about food, compared to Baseline. Following Body Scanning and Thought Suppression, food thoughts returned to Baseline frequencies Post-task, rather than rebounding. There were no effects of the interventions upon craving, although overall, craving and thought frequency were correlated. Thought control tasks may help people to ignore thoughts about food and thereby reduce their temptation to snack.
