Ep.23: Nutrition While on GLP-1 Medications: What Early Research Shows

GLP-1 medications are transforming weight loss conversations — but what about nutrition? In this episode, Naturopaths Kathleen and Michelle unpack the science behind GLP-1 therapies and explore what happens when appetite drops but nutrient needs remain. Drawing on recent research, they discuss protein requirements, muscle preservation, micronutrient deficiencies, digestive side effects, and why nutrient density becomes critical during weight loss. With practical strategies and clinical insight, this episode highlights the importance of intentional, evidence-informed nutrition alongside medication use. If you’re using GLP-1 therapies — or considering them — this is the conversation you don’t want to miss.
