Individuals using GLP-1 medications (Ozempic, Wegovy Mounjaro) or transitioning off them who feel overwhelmed by hunger changes, food noise, or fear of weight regain. Many have tried dieting or received limited guidance beyond medication. They are often referred by physicians or seeking a structured, evidence-based approach. I help them understand what is happening physiologically and follow a clear process to stabilize, reduce anxiety around food, and move forward with confidence.
