允许员工预订午餐的在线系统可能有助于减少能量摄入。我们调查了一个工作场所食堂的预购网站的可接受性，促使客户交换到低能耗的交换和影响交换接受的因素。员工（n = 30）通过一个为他们的食堂设计的预定网站，同时大声思考一个假设的午餐订单。半结构化访谈问题支持数据收集。采用专题分析法对数据进行了分析。可接受性普遍较高，但可能取决于具体情况。实用的考虑因素，如提醒预订，用户友好性，提供菜单项的图像和能源信息，同时浏览，预订餐的能力，并迅速收集服务促进接受。下单的时间限制、在下单前没有机会看到食物以及被视为威胁自主权的交换提示，都是妨碍接受的障碍。交换接受促进了身体活动卡路里当量（PACE）信息的提供，和交换的味道，质地和预期的饱腹感方面的相似性，以及替代品提供有意义的节能的看法。在线食堂预订系统，促使低能量交换可能是一个可以接受的方法，以帮助减少工作场所的能量摄入。
Online systems that allow employees to pre-order their lunch may help reduce energy intake. We investigated the acceptability of a pre-ordering website for a workplace canteen that prompts customers to swap to lower-energy swaps and the factors influencing swap acceptance. Employees (n = 30) placed a hypothetical lunch order through a pre-ordering website designed for their canteen while thinking aloud. Semi-structured interview questions supported data collection. Data were analysed using thematic analysis. Acceptability was generally high, but potentially context dependent. Practical considerations, such as reminders to pre-order, user-friendliness, provision of images of menu items and energy information while browsing, an ability to reserve pre-ordered meals, and a swift collection service facilitated acceptability. The restrictive timeframe within which orders could be placed, a lack of opportunity to see foods before ordering, and prompts to swap being perceived as threatening autonomy were barriers to acceptability. Swap acceptance was facilitated by the provision of physical activity calorie equivalents (PACE) information, and swap similarity in terms of taste, texture, and expected satiety as well as the perception that alternatives provided meaningful energy savings. Online canteen pre-ordering systems that prompt lower-energy swaps may be an acceptable approach to help reduce energy intake in the workplace.
