Dietary habits are not only impacting on our health, but also the environment, with concerns being raised over the sustainability of an animal-based diet in particularly and a push towards mindful dietary choices \citep{Springmann2016}. Greater adoption of the vegetarian diet would reduce water, energy, fertiliser and pesticide use, subsequently improving both the environment and individual health \citep{Marlow2009}. The Mediterranean diet (which is low in meat) has also been proposed as a way to both improve the environment along with individual heath \citep{Sáez-Almendros2013}. As a result of the growing concern surrounding a diet based on animal products for both individual health and the environment, encouragements such as the VB6 (vegan before 6pm) diet or flexitarianism (flexible vegetarianism) have been proposed to battle both growing issues (Bittman, 2013; Raphaely & Marinova, 2012; Raphaely & Marinova, 2014). Interest in vegetarianism and veganism is continually growing as people become more mindful and ethical of their dietary choices , with trends such as "Veganuary" (being vegan for the month of January) growing (The Vegan Society, 2019).
