Disordered eating refers to a particular relationship with food that is not just about eating to live. Rather, food plays an important psychological role in how an individual copes with e.g. stress; emotional issues but it does not meet the criteria for an eating disorder. It is nonetheless a problem that can fill the person’s daily thoughts and it can affect various aspects of life, including relationships, socialisation, general activities and of course self-esteem.
