Recent studies suggest that while veganism is generally beneficial for overall well-being, its strict and rule-based nature can potentially increase the risk of disordered eating for individuals motivated by weight or perfectionism. While the majority of vegans appear psychologically healthy, research has shown a higher prevalence of vegetarian or vegan diets among individuals with eating disorders, particularly those with anorexia nervosa.

The motivation behind adopting a vegan diet plays a significant role in determining the potential risks for disordered eating. Weight-control motives have been linked to higher dissatisfaction and rigidity, while ethical or environmental concerns correlate with better body-image scores. It is essential to be mindful of one's reasons for choosing a vegan diet, practice flexibility, and prioritize mental well-being to ensure a balanced relationship with food and maintain overall health.
