Consumption of animal products is an important greenhouse gas emitting behavior. However, perceived hindrances to incorporating more plant-based diets present challenges for the successful design of behavior-change interventions. Latent profile analysis of survey responses revealed three distinct groups. Meat-reducers perceive the fewest inhibitors and are the most willing to incorporate more meat-free days in their diets. Moderate-hindrance meat eaters perceive many more inhibitors, and are hindered by a lack of social support, attachment to meat, not wanting to change their routine, and less awareness of the health benefits of eating less meat. They are willing to incorporate new healthy foods in their diet and are somewhat willing to avoid meat on some days. Strong-hindrance meat eaters report weak self-efficacy and the most inhibitors but are somewhat willing to incorporate healthier foods in their diets. Implications for tailored meat-reduction interventions are discussed. For example, when targeting meat-attached individuals, it might be beneficial to focus on replacing red meats with less carbon-intensive protein sources.
食用动物产品是一种重要的温室气体排放行为。然而，人们认为食用更多植物性饮食的障碍给成功设计行为改变干预措施带来了挑战。对调查回复的潜在特征分析揭示了三个不同的群体。减少肉类摄入量的人认为他们受到的阻碍最少，并且最愿意在饮食中增加更多无肉日。中度障碍的肉食者认为他们受到的阻碍更多，他们受到缺乏社会支持、对肉类的依恋、不想改变日常生活以及对少吃肉的健康益处认识不足的阻碍。他们愿意在饮食中加入新的健康食品，并且在某些日子里有点不愿意吃肉。强烈障碍的肉食者报告说自我效能感较弱，受到的阻碍最多，但他们有点愿意在饮食中加入更健康的食物。讨论了针对量身定制的肉类减少干预措施的影响。例如，当针对喜欢吃肉的人时，专注于用碳排放量较低的蛋白质来源替代红肉可能会有所帮助。
