Although the inclusion of individuals with lived experience is encouraged within the research process, there remains inconsistent direct involvement in many mental health fields. Within the eating disorders field specifically, there is a very strong and increasing presence of lived experience advocacy. However, due to a number of potential challenges, research undertaken in consultation or in collaboration with individuals with lived experience of an eating disorder is scarce. This paper describes the significant benefits of the inclusion of individuals with lived experience in research. The specific challenges and barriers faced in eating disorders research are also outlined. It is concluded that in addition to existing guidelines on working with lived experience collaborators in mental health research, more specific procedures are required when working with those with eating disorders.
