The Evolving Role of Registered Dietitian Nutritionists in Obesity

In this episode of Diabetes Dialogue: Technology, Therapeutics, and Real-World Perspectives, hosts Diana Isaacs, PharmD, and Natalie Bellini, DNP, are joined by Allison Evert, MS, RD, CDCES, and Savitha Subramanian, MD, co-authors of a recent publication on the evolving role of registered dietitian nutritionists (RDNs) in incretin-based therapies and obesity care, titled "Incretin-Based Therapies and Lifestyle Interventions: The Evolving Role of Registered Dietitian Nutritionists in Obesity Care". The conversation explores how combining GLP-1 receptor agonists with lifestyle interventions can enhance long-term outcomes in diabetes and obesity management, focusing on the integral role of RDNs in addressing medication adherence, side effects, and patient education.Evert and Subramanian highlight key findings from their paper, including strategies for mitigating side effects such as nausea, constipation, and diarrhea, which contribute significantly to high discontinuation rates during the first year of therapy. They stress the importance of counseling patients on appropriate dietary adjustments to prevent nutrient deficiencies and muscle loss during rapid weight loss, recommending an emphasis on protein intake and nutrient-dense food choices.The discussion also delves into the practical challenges of integrating RDNs into care teams, particularly in systems with limited resources. To address this gap, the authors provide actionable tools in their paper, including figures and resources to guide clinicians in patient education and medication management. The hosts and guests agree that team-based care, including the use of pharmacists, advanced practice providers, and clinical protocols, is critical to improving outcomes and ensuring the long-term success of these therapies.Relevant disclosures for Isaacs include Eli Lilly and Company, Novo Nordisk, Sanofi, Abbott Diabetes Care, Dexcom, Medtronic, and others.
