Dietetic intervention for adult outpatients with an eating disorder: a systematic review and assessment of evidence quality.

There is currently limited evidence to sufficiently assess the impact of incorporating dietetic interventions into outpatient treatment for adults with an ED; however, available evidence supports clinical practice guidelines that dietetic intervention should not be delivered as a stand-alone treatment. Additional methodologically sound studies in larger samples are required to fully inform dietetic treatment in EDs and incorporation of such interventions as part of a multidisciplinary treatment approach.
