Abstract

Abstract Understanding behaviours driving recent declines in UK meat consumption is essential for achieving the Climate Change Committee’s 20% reduction target by 2030. This study explored trends in meat-eating days, daily meat-eating meal occasions, and portion size of meat from the National Diet and Nutrition Survey (2008/09-2018/19). Meat consumption was assessed using 4-day food diaries. Trends were assessed with Poisson and linear regression models, while decomposition analysis quantified relative contributions to overall reductions. Meat-eating days decreased from 3.27 (0.04) to 3.03 (0.05) (P < 0.001), daily occasions decreased from 1.24 (0.02) to 1.13 (0.03) (P = 0.01), and portion size decreased from 85.8g (1.85) to 76.1g (1.78) (P < 0.001). Reduction in portion size had the largest impact on total meat consumption (57%), followed by days (37%) and occasions (6%). Our findings suggest smaller meat portions significantly contributed to decreasing UK meat consumption. Dissecting these behaviours can inform interventions to reduce meat consumption, aligning with reduction targets.
