Smaller meat portions contribute the most to reducing meat consumption in the United Kingdom

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.
