Dietitian Connection

Glenn Mackintosh joins DC’s Jane Winter to talk about how dietitians can better incorporate essential conversations into our practice to ensure our clients are set-up for long term success. From identifying if a client is truly ready to embark on a weight loss journey to helping them zoom out from the scales and set realistic, holistic goals. We also touch on the defence mechanism that is emotional eating, how to make your clients aware of it, and why it’s important that clients do a social media spring clean to improve their relationship with their own body.
