Facilitating change in client behavior is a key challenge for registered dietitian nutritionists (RDNs). RDN frustration occurs when clients do not adhere to the behavior change plans developed during consultations.1 The client may return for future appointments having made minimal or no lifestyle changes, or showing a decline in diet and physical activity behaviors. Despite many clients having the knowledge, skills, and need to make nutritious dietary choices and to participate in regular physical activity, many still struggle to maintain behavior change in the long term.
