Many people do not consume as much healthy food as recommended. Nudging has been identified as a promising intervention strategy to increase the consumption of healthy food. The present study analyzed the effects of three body shape nudges (thin, thick, or Giacometti artwork) on food ordering and assessed the mediating role of being aware of the nudge. Students (686) and employees (218) of a German university participated in an online experimental study. After randomization, participants visited a realistic online cafeteria and composed a meal for themselves. Under experimental conditions, participants were exposed to one out of three nudges while choosing dishes: (1) thin body shape, (2) thick body shape, and (3) the Giacometti artwork nudge. The Giacometti nudge resulted in more orders for salad among employees. The thin and thick body shape nudges did not change dish orders. Awareness of the nudge mediated the numbers of calories ordered when using the Giacometti or thin body shape nudges. These findings provide useful insights for health interventions in occupational and public health sectors using nudges. Our study contributes to the research on the Giacometti nudge by showing its effectiveness when participants are aware (it is effective under conditions where it is consciously perceived).
许多人没有按照建议摄入足够的健康食物。轻推已被确定为一种有前途的干预策略，可以增加健康食物的消费。本研究分析了三种体型轻推（瘦、胖或贾科梅蒂艺术品）对点餐的影响，并评估了意识到轻推的中介作用。德国一所大学的学生（686 人）和员工（218 人）参与了一项在线实验研究。在随机分组后，参与者访问了一个逼真的在线自助餐厅，并为自己搭配了一份餐食。在实验条件下，参与者在选择菜肴时会接触到三种轻推中的一种：（1）瘦体型，（2）胖体型，和（3）贾科梅蒂艺术品轻推。贾科梅蒂的轻推导致员工点沙拉的数量增加。瘦体型和胖体型的轻推并没有改变菜肴的订单。当使用贾科梅蒂或瘦体型轻推时，对轻推的意识会影响所点的卡路里数量。这些发现为使用轻推进行职业和公共卫生领域的健康干预提供了有用的见解。我们的研究通过显示参与者意识到（在有意识感知的情况下有效）时贾科梅蒂轻推的有效性，为贾科梅蒂轻推的研究做出了贡献。
