Abstract
<jats:p>Avoidant restrictive food intake disorder (ARFID) was first introduced as a diagnosis in the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders‐5 in 2013 and then added to the 11th revision of the International Classification of Diseases published in 2022. A dietitian is unable to make an ARFID diagnosis but can recommend further assessment with a physician or psychologist if it is suspected. Treatment is usually delivered by a multi‐disciplinary team, and dietetic input is key from assessment to discharge. Dietetic care is usually delivered in outpatient clinics, but sometimes needs acute care on the ward. The successful treatment of ARFID is not yet evaluable with any specific monitoring protocol or standardised outcome measure. Progress on psychosocial functioning and anxiety metrics, as well as anthropometrics, blood tests, blood pressure and nutritional risk, are useful in a multidisciplinary evaluation of treatment progress.</jats:p>
