Reducing meat consumption can help improve environmental and health outcomes, yet the effect of specific meat-reducing strategies is context dependent. Here, using decomposition analysis of National Diet and Nutrition Survey data (2008–2009 to 2018–2019), we found that in the United Kingdom, reduced meat portions had the largest impact on total meat consumption decline (52%), followed by fewer meat-eating days (24%), fewer meat consumers (17%) and fewer meat-eating meal occasions (7%). Understanding meat consumption behaviour patterns is key for more effective policies.
