In an increasingly obesogenic environment, an individual's regulatory capacity to pursue nutrient-rich, low-calorie foods over palatable, energy-dense items is essential to maintaining a healthy weight and preventing the detrimental health risks of obesity. Cognitive reappraisal, the process by which one changes the meaning of a stimulus by altering its emotional impact (or in this case, its appetitive value) demonstrates promise as a regulatory strategy to decrease obesogenic food consumption, but little research has directly addressed the relationship between cognitive reappraisal of food cravings and real-world eating behaviors. Additionally, research examining self-regulation of eating has typically focused exclusively on diminishing cravings and consumption of unhealthy, high-calorie foods, rather than examining, in tandem, ways to strengthen (or, up-regulate) cravings for healthier, low-calorie alternatives. In the present study, fifty-seven college aged participants first completed a cognitive reappraisal task in the laboratory in which they practiced regulating their craving responses to high- and low-calorie food items by focusing on the long-term health consequences of repeatedly consuming the pictured foods. Next, for a week following the laboratory session, participants reported daily eating behaviors via ecological momentary assessment. Participants who reported greater up-regulatory success during the reappraisal task also reported increased craving strength for low-calorie foods as well as decreased consumption of high-calorie foods in their daily lives. Greater overall regulation success also predicted more frequent consumption of craved low-calorie foods. These findings substantiate the association between cognitive reappraisal ability and real-world appetitive behaviors, and suggest that future interventions may benefit from specifically targeting individuals' evaluations of low-calorie foods.
在日益肥胖的环境中,个体追求营养丰富、低热量食物而不是美味、高热量食物的调节能力对于维持健康体重和预防肥胖带来的有害健康风险至关重要。认知重评是一种通过改变刺激的情绪影响(或者在这种情况下,改变其食欲价值)来改变其意义的过程,它作为一种调节策略,有望减少促肥胖食物的消费,但很少有研究直接探讨食物渴望的认知重评与现实世界的饮食行为之间的关系。此外,研究饮食自我调节的研究通常只关注减少对不健康、高热量食物的渴望和消费,而不是同时研究增强(或上调)对更健康、低热量替代品的渴望的方法。在本研究中,57 名大学生首先在实验室完成了一项认知重评任务,在该任务中,他们通过关注反复食用所描绘食物的长期健康后果来练习调节对高卡路里和低卡路里食物的渴望反应。接下来,在实验室会议后的一周内,参与者通过生态瞬间评估报告每日的饮食行为。在重评任务中报告更大的上调成功的参与者也报告在日常生活中对低卡路里食物的渴望强度增加,以及对高热量食物的消费减少。总体调节成功的增加也预示着对渴望的低卡路里食物的更频繁消费。这些发现证实了认知重评能力与现实世界的食欲行为之间的关联,并表明未来的干预措施可能受益于专门针对个体对低卡路里食物的评估。
