Successful behavioral interventions to reduce the consumption of unhealthy food will ease burden of NCDs and its economic cost. In prior research, conventional approach such as nutrition information could not overcome the impact of tasty but unhealthy food. Thus, this study is designed a field experiment at a casual restaurant to assess the effects of taste and behavioral approach, particularly the combination of convenience and visibility enhancements on healthier meal choices. The results of this study show that adding difficulty in ordering high-calorie food along with visibility can reduce calorie intake and compensate for the calorie increase caused by ordering according to taste. However, there are differences in effectiveness of interventions across each type of participant.

选择决策的行为干预：便利性和可见性干预与口味偏好

减少不健康食品消费的成功行为干预将减轻非传染性疾病的负担及其经济成本。在先前的研究中，营养信息等传统方法无法克服美味但不健康食品的影响。因此，本研究在一家休闲餐厅设计了一项实地实验，以评估口味和行为方法的影响，特别是便利性和可见度增强对更健康的膳食选择的影响。这项研究的结果表明，增加点高热量食物的难度以及能见度可以减少卡路里的摄入，并补偿因按口味点餐而导致的卡路里增加。然而，不同类型参与者的干预效果存在差异。
