Latest podcast: The biology of sustainable weight loss

In this podcast episode, Emma Sutherland speaks with Dr Nick Fuller, Clinical Trials Director at the Royal Prince Alfred Hospital Endocrinology Department and researcher at the Charles Perkins Centre. Together they unpack the complex physiology behind weight regain, including metabolic adaptation, appetite-hormone shifts, and the evolutionary mechanisms that make long-term weight loss so challenging.

Nick explains how even small amounts of weight loss can trigger significant biological compensations, why traditional dieting approaches often fail, and how interval-based weight management can help prevent the rebound effect commonly seen in clinical practice. The discussion also explores emotional eating, circadian influences on hunger, and the importance of balanced meals, sleep routines, daily activity, and a whole-foods approach to support metabolic health.  

This episode provides practitioners with a grounded, evidence-informed lens for guiding patients through sustainable, long-term weight change.
