Calorie labels on restaurant menus: What do consumers see, think, and decide? Eye-tracking and interview insights
通过眼动追踪和访谈，研究了36名消费者对餐厅菜单卡路里标签的注意与使用情况，发现多数人未主动注意或使用标签，选择主要受愉悦感和饮食限制驱动。
This study explores consumers’ reactions and responses to calorie labelling of restaurant menus. A convenience sample of 36 participants aged 18 and older, who dine out at least monthly, engaged with menus using eye-tracking technology to measure involuntary attention. Participants visited the lab twice: first with a menu without calorie labelling and, at least two weeks later, with the same menu including calorie information. After each session, follow-up interviews explored the reasons behind attention, reactions, and food choices. Results revealed that while some subconscious attention to calorie information was detected through eye-tracking, many participants did not consciously notice it. Even those who saw calorie information rarely used it to inform choices, with calorie reductions failing to reach statistical significance. Choices were primarily driven by enjoyment and dietary restrictions. These findings suggest calorie labelling may have limited effectiveness in occasional social dining contexts and interventions should target regular dining venues instead.
