The Holistic GLP-1 Podcast with Elizabeth McGann

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.

If you've been hearing about GLP-1 medications and wondering whether they might help you—but you feel nervous, skeptical, or unsure—this episode is a powerful place to begin.
In this deeply personal conversation, Elizabeth sits down with GLP-1 advocate and content creator Rachael Gullette, who has lost more than 160 pounds on a GLP-1 medication. Rachael shares what life felt like before treatment, how food noise ruled her inner world, and how discovering that obesity is a disease—not a character flaw—changed everything.
This is a raw, hopeful, eye-opening episode about food noise, binge eating, ADHD, shame, stigma, infertility, inflammation, and the kind of freedom that feels almost impossible until you experience it for yourself.
