Professor David Scott - Beyond the Scales: Preserving Muscle and Bone Health During Weight Loss
As GLP-1 medications become increasingly integrated into weight management, understanding their implications for muscle and bone health is essential for practitioners supporting patients through significant weight loss. In this episode, Laurence Katsaras is joined by Professor David Scott, exercise scientist and NHMRC Emerging Leadership Fellow at Deakin University, to explore the latest research on GLP-1 therapies and body composition. They discuss the relationship between weight loss and lean mass reduction, the distinction between muscle loss and changes in muscle composition, and the potential implications for long-term physical function, bone health and fracture risk.
David shares practical, evidence-informed strategies to help practitioners support healthy body composition throughout the weight loss journey. From protein requirements and nutritional considerations to the importance of progressive resistance training, he outlines how specialised exercise prescription can help minimise muscle and bone loss. The conversation also explores accessible clinical tools for monitoring body composition and physical function, strategies for supporting sustainable behaviour change, and the opportunities for practitioners to provide individualised lifestyle support. Discover how integrating targeted nutrition, exercise and ongoing monitoring can help patients achieve healthier, more sustainable outcomes while using GLP-1 therapies.

David Casteleijn - Herbal Heroes: A Modern Clinical Lens on Globe Artichoke
Globe artichoke has a long history in Western herbal medicine, yet its broad applications can be easy to overlook in an era of increasingly targeted therapeutic approaches. In this episode, we welcome David Casteleijn back to the MediHerb Podcast to explore why this classic herb deserves renewed attention. David shares his clinical experience using globe artichoke as a general digestive tonic, supporting digestive function, while considering its bitter principles, choleretic and cholagogue actions, and prebiotic fructans.
The conversation takes a deeper look at where globe artichoke may fit in contemporary naturopathic practice, including digestive dysfunction associated with nervous system dysregulation and the complex relationship between the gut, microbiome and nervous system. David also discusses the apparent contradiction of using a fructan-containing herb in people with IBS, challenging an overly symptom-focused approach to FODMAPs and highlighting the importance of considering the whole person. With insights from his observational research into herbal medicine use in anxiety and depression, this episode offers a fresh clinical perspective on a versatile herb that deserves a place in your dispensary.
