A high food intake can contribute to increased greenhouse-gas emissions, and therefore consumers with a high energy intake are important to include when exploring sustainable foodways. In this paper, semi-structured interviews and a seven-day food record were used to understand the climate impact of food, analyse mundane food practices, and identify sustainable routines among high-energy consumers represented by a group of recreational athletes. Social practice theory and the interdependent relationship between competence, material, and meaning unfold an with a focus on performance, time-saving strategies, structured eating, and a possible where the food practice also includes important sustainability aspects. The results indicate a high carbon footprint from high energy and dairy and whey protein intake. Some recreational athletes demonstrate an awareness of the climate impact of food, but they need to be convinced that more sustainable ways are possible without jeopardising athletic performance.
高食物摄入量可能会导致温室气体排放增加，因此在探索可持续的饮食方式时，需要将高能量摄入的消费者纳入考虑范围。在本文中，我们采用半结构化访谈和为期七天的食物记录，以了解食物对气候的影响，分析日常饮食实践，并确定由一组娱乐运动员代表的高能量消费者的可持续生活习惯。社会实践理论和能力、物质和意义之间的相互依存关系展开了一个分析框架，重点关注表现、节省时间的策略、有规律的饮食以及一个可能的未来，其中食物实践也包含了重要的可持续性方面。研究结果表明，高能量和乳制品及乳清蛋白摄入会导致较高的碳足迹。一些娱乐运动员已经意识到食物对气候的影响，但他们需要确信，在不影响运动表现的情况下，还有可能采取更可持续的方式。
