“…Other reviews discussed meat reduction or plant-based diets/alternatives within the context of health promotion ( Corrin and Papadopoulos, 2017 ; Bryant, 2022 ), pro-environmentalism ( Hartmann and Siegrist, 2017 ; Bryant, 2022 ) and animal protection ( Mathur et al, 2021 ). In addition, various theories have been applied to examine meat-eating ( Povey et al, 2001 ; Graça et al, 2016 ; Grünhage and Reuter, 2021 ), including cognitive dissonance theory ( Festinger, 1962 ) to gain insight in the meat paradox (“how can people care about animals, but also eat them?”) ( Loughnan et al, 2014 ; Lin-Schilstra and Fischer, 2020 ) and the psychology of meat-eating as a morally questionable and dissonance-arousing activity ( Bastian and Loughnan, 2017 ; Rothgerber, 2020 ). This vast literature indicates that the promotion of meat reduction and veg*n dietary changes is held back by a complex and diverse set of barriers, involving both macro-level historical, economic, political, technological and societal barriers and micro-level psychological barriers concerning awareness and habitual behavior, conflicting goals and values, ambivalent feelings and moral disengagement ( Graça, 2016 ; Graça et al, 2019 ; Harguess et al, 2020 ).…”
