(1) Background: The aim of the current study is to investigate which between- and within-person factors influence the acceptance of personalized dietary advice. (2) Methods: A repeated measurements design was used in which 343 participants (M (SD) age = 48 (17.3), 49% female) filled out a baseline survey and started with nine repeated surveys. (3) Results: The results show that the acceptance of personalized dietary advice is influenced by both within-person and between-person factors. The acceptance is higher at lunch compared to breakfast and dinner, higher at home than out of home, higher at moments when individuals have a high intention to eat healthily, find weight control an important food choice motive and have a high healthy-eating self-efficacy. Moreover, the acceptance is higher when individuals do not see the eating context as a barrier and when individuals believe that personalized dietary advice has more benefits than risks. (4) Conclusions: Future behavioral interventions that use personalized dietary advice should consider the context as well as individual differences.
(1) 背景：本研究旨在探讨哪些个体内和个体间因素会影响对个性化饮食建议的接受度。(2) 方法：本研究采用重复测量设计，共有 343 名参与者（M（SD）年龄=48（17.3），49%为女性）填写了基线调查问卷，并开始进行九次重复调查。(3) 结果：结果表明，对个性化饮食建议的接受度受到个体内和个体间因素的影响。与早餐和晚餐相比，午餐时接受度更高；与外出就餐相比，在家就餐时接受度更高；当个体有较高的健康饮食意愿、将控制体重视为重要的食物选择动机以及具有较高的健康饮食自我效能感时，接受度更高。此外，当个体不将饮食环境视为障碍，并且认为个性化饮食建议的益处大于风险时，接受度也会更高。(4) 结论：未来使用个性化饮食建议的行为干预措施应考虑到个体差异和环境因素。
