What if the real key to successful, sustainable weight loss isn’t starting a GLP-1—but fixing your gut first?In this eye-opening episode, I sit down with Dr. Oscar Coetzee, a leading expert in clinical nutrition and gut health, to unpack the critical (and often overlooked) role the microbiome plays in metabolism, cravings, and natural GLP-1 production.We explore why starting a GLP-1 with poor gut health can backfire, how specific bacteria influence hunger hormones and dopamine, and the emerging science behind “keystone” microbes that may control up to 85% of your metabolic function.If you’re considering a GLP-1, currently on one, or looking for a more natural, root-cause approach to weight loss—this conversation is essential.This episode will change how you think about your gut—and your path to lasting results.***SHOW NOTES[ 00:00 ] Introduction: A Critical Warning Before Starting GLP-1[ 04:00 ] Is the Gut Actually the First Brain?[ 08:00 ] From Psychology to Microbiome Medicine[ 12:00 ] The Microbes That Control Your Hunger Hormones[ 16:00 ] The Gut as an Ecosystem (The “Earthworm” Analogy)[ 20:00 ] Why Probiotics Alone Aren’t Enough[ 24:00 ] The Real Driver of Cravings and Overeating[ 28:00 ] The Fiber Crisis (and Why It Matters)[ 32:00 ] Signs Your Gut Is Holding You Back[ 36:00 ] Functional Testing: The Missing Diagnostic Tool[ 40:00 ] Why “Killing Bad Bacteria” Can Make Things Worse[ 44:00 ] The Breakthrough: Keystone (Anaerobic) Bacteria[ 48:00 ] Case Study: Reversing Food Sensitivities Naturally[ 52:00 ] How Gut Health Directly Drives GLP-1 Production[ 56:00 ] Why GLP-1 Results Plateau (and How to Fix It)[ 1:00:00 ] The 5 Bacteria That Control 85% of Your Metabolism[ 1:04:00 ] The Hidden Cost of GLP-1 Medications[ 1:08:00 ] Testing Your Metabolic Health Beyond the Scale[ 1:12:00 ] The Simplest (and Most Powerful) Gut-Healing Strategy[ 1:16:00 ] Final Takeaways: Build the Foundation First***Get Connected with Elizabeth McGann:Coaching Website: http://www.ElizabethMcGann.comInstagram: http://www.instagram.com/elizabethmcgannFacebook: https://www.facebook.com/ElizabethMcGannWellnessLinkedIn: https://www.linkedin.com/in/elizabethmcgannX/Twitter: https://twitter.com/ElizabethMcGann***Learn more about Dr. Oscar CoetzeeDr. Coetzee's Website: https://naturalhealthcarecenter.comInstagram: https://www.instagram.com/droscarcoetzee/
