Dr. Jon Campbell: Understanding GIP and Glucagon | Ep. 14

In this episode of The GLP-1 Podcast Show, I speak with Dr. Jon Campbell, Associate Professor of Medicine at Duke University, about the changing science of GIP and glucagon. We examine GIP physiology, glucagon signaling, weight-independent metabolic effects, multi-receptor agonism, and variability in treatment response. Discover how emerging pharmacology could shape more precise obesity treatment. Listen now on all major platforms.

"GI think it’s going to take a little while, but people are going to come around to this idea that glucagon, particularly when combined with an incretin like GIP or GLP-1, is a really powerful way to improve metabolic disease."

Meet the guest: Dr. Jon Campbell is an Associate Professor of Medicine at Duke University. His research examines incretin hormones, pancreatic islet biology, and the cellular mechanisms that regulate glucose metabolism. His work has helped advance understanding of GIP, GLP-1, glucagon, and the signaling pathways that may shape future metabolic therapies.
