The Science-Backed Bitter Compound That Mimics GLP-1 (No Injections Needed!)

I’ve been watching the science behind Calocurb evolve over the last year, and I have to say—this is one of the most exciting clinical tools I’ve seen emerge in the metabolic space in quite some time. A hops-derived compound that stimulates endogenous GLP-1, CCK, and PYY—without a prescription or injection? That’s a big deal, especially for patients struggling with appetite regulation, weight plateaus, or the aftermath of GLP-1 discontinuation. In this episode, I sit down with Sarah Kennedy, founder of New Zealand-based Calocurb, to talk about the years of government-funded research that led to this discovery, the remarkable clinical outcomes they’ve seen so far, and how I’ve personally used it in my practice with excellent results. If you’re looking for science-backed, natural strategies to support appetite control, fasting, or GLP-1 transitions—this one’s worth a listen. ~DrKF Check out the show notes at https://www.drkarafitzgerald.com/fxmed-podcast/ for the full list of links and resources.

10 Year Anniversary: What I Learned After 200+ Conversations with the Best Minds in FxMed

In this very special episode, I have the privilege of turning the tables on Dr. Kara Fitzgerald as we celebrate 10 years of the New Frontiers podcast. I’ve been honored to walk alongside Kara on much of this journey—as a colleague, a collaborator, a mentee, and a friend—and it’s been incredible to witness the evolution of both her work and the field itself. Together, we reflect on the stories, science, and people who have shaped this podcast—and the remarkable growth of epigenetics, personalized medicine, and functional medicine along the way. From early conversations around methylation and aging to hosting pioneers like Dr. Jeff Bland, Dr. Sidney Baker, and Dr. Charles Serhan, New Frontiers has become a living archive of how this field has moved forward. As we talked about during the conversation: “Everybody is a piece of this ecosystem, and everybody has their role... It’s really cool to be part of that community.” This episode is a celebration of that collective journey—and a look at where we’re headed next. ~Romilly Hodges MS CNS Check out the show notes at https://www.drkarafitzgerald.com/fxmed-podcast/ for the full list of links and resources.

Dead Mitochondria Might Be Fueling Cardiovascular Aging — Here’s The Fix

This is a really exciting conversation with Dr. Davide D’Amico from Timeline, where we’re taking a closer look at Urolithin A and heart health. It should come as no surprise that this mitochondrial wonderkin of a nutrient is showing promise here—especially when you consider that 40% of the heart’s weight is mitochondria. That’s an extraordinary factoid, and one that really shifts how we think about aging in the cardiovascular system. What’s particularly compelling in this new preclinical research is that restoring mitochondrial function may do more than just improve ejection fraction. It may also have ripple effects on other hallmarks of aging—like chronic inflammation, cellular stress signaling, and impaired autophagy. I’m thrilled Timeline is continuing to invest in both preclinical and clinical research on this front—and yes, I’m totally nerding out over what they’re up to. ~DrK Check out the show notes at https://www.drkarafitzgerald.com/fxmed-podcast/ for the full list of links and resources.

Why You’re Aging Faster Than You Think & How to Slow It

I’ve been looking forward to sharing this conversation with you because it’s one I’m truly passionate about. Today, we’re diving into the DunedinPACE epigenetic clock with one of its creators, the brilliant Dan Belsky. It’s a tool I use regularly with my patients, and one that’s transforming how we approach aging and interventions. While this show is a bit more technical than usual, the science is fascinating, and the real-world applications are incredibly valuable. This isn’t just about theory—it’s about practical insights that can change how we measure aging and track the effectiveness of the treatments we offer.

The Truth About Chronic Illness: How to Reset Your Nervous System & Slow Aging

We’ve all had patients struggling with chronic conditions like long COVID, fibromyalgia, Lyme disease, and chronic fatigue. Despite all the tools in our functional medicine toolkit, there’s still something missing. How can we truly help them? I’m excited to have Ashok Gupta back on the New Frontiers podcast to offer a new take on healing from chronic illness. He explains that many chronic diseases stem from a malfunction in the brain's threat detection system, where the body overreacts to perceived threats, triggering immune, nervous system, or mood responses, creating a vicious cycle. Ashok shares how retraining the brain and calming the nervous system can reset the body’s response to chronic stress and presents the growing body of research supporting the Gupta Program, including new subjective measurements like CRP showing its impact. What excites me most is the potential for this approach to help some of my toughest-to-treat patients. With more studies emerging, I’m increasingly hopeful this could be a game-changer.

p-Tau 217: The Breakthrough Biomarker Revolutionizing Early Alzheimer’s Detection

Join me for a fascinating conversation around an exciting breakthrough in dementia detection that’s offering real hope for early intervention. Dr. Hans Frykman, Chief Scientific Officer at Neurocode Laboratories, is here to share groundbreaking insights into cutting-edge biomarkers that can identify pathology associated with Alzheimer's disease before symptoms even appear. What’s even more fascinating is how these same tools are revealing neuroinflammation caused by infections, including COVID, Lyme disease, and mold exposure—issues that are incredibly relevant in functional medicine today. The assays Dr. Frykman and his team have developed, and continue to research, are transforming the way we think about diagnosing and addressing neurodegeneration. We’re talking about a potential game-changer that allows us to intervene earlier, reverse damage, and ultimately improve the trajectory of these conditions. This is an extraordinary time in science and medicine, and the work we’re discussing today is at the forefront of it all.
