  1. Why Centenarians Are Defying Science: Secrets to Living 100+

    18 AUG

    Why Centenarians Are Defying Science: Secrets to Living 100+

    It was a pleasure to sit down with Dr. Nir Barzilai for a conversation that turned out to be both lively and thought-provoking. His decades of research on centenarians, biological age, and the hallmarks of aging have shaped how we think about longevity—and what’s possible when we start targeting aging itself, not just individual diseases. We get into the science behind why some people live 20–30 years longer and healthier, and what it means to measure the biological age of individual organs. But we also hit a few sparks—especially when it comes to nutraceuticals and the role of metformin in prevention. I don’t agree with everything you’ll hear, and I followed up with Dr. Barzilai afterward to unpack some of the more provocative claims. We may just need a second round for this one... stay tuned.

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

    5 AUG

    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.

  3. 10 Year Anniversary: What I Learned After 200+ Conversations with the Best Minds in FxMed

    23 JULY

    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.

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

    8 JULY

    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.

  5. Why Human-Centered AI Is the Future of Medicine & Mental Wellness

    23 JUNE

    Why Human-Centered AI Is the Future of Medicine & Mental Wellness

    This episode is a little different from what we usually cover on New Frontiers, but it’s one I couldn’t wait to bring to you. I’ve been thinking a lot about how we—as clinicians—are supposed to keep up in this era of high-throughput technology. We’re swimming in data: labs, multi-omics, diet logs… and an ever-growing stream from wearables. There’s just so much coming at us, and too often, we’re awash in a sea of information without adequate interpretive power. That’s why this conversation with Dr. Rana el Kaliouby felt so important. She’s not just an AI scientist—she’s a visionary and a total badass. She’s building technology that doesn’t just process data, but actually helps us become better clinicians and better humans. We get into the ethics, the potential, the parenting implications—and yes, a personal story about a tragedy in my own hometown that made this all hit very close to home. This one’s powerful, and I hope it sparks the same questions and inspiration for you as it did for me. ~DrKF TRIGGER WARNING This episode touches on sensitive topics, including gun violence and suicide, in the context of empathy, mental health, and technology. If you or someone you know is struggling, please seek help. We share this with care and hope it offers support and perspective.

    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. Stick with us, and you’ll walk away with actionable knowledge that can make a difference in your practice. ~DrKF Check out the show notes at https://www.drkarafitzgerald.com/fxmed-podcast/ for the full list of links and resources.

    What New Research Says About Cartilage Regeneration and Joint Longevity

    What if a human trial of over 1200 patients showed improved mobility and reduced pain in osteoarthritis (OA) patients using a natural combination of boswellia and celery seed extract? What if a second follow-up randomized, placebo-controlled human trial found that within 90 days, this same combination increased OA patients' ability to perform a walk test by over 50%, reduced markers of cartilage degeneration by half and increased markers of cartilage regeneration by half. This is what the research team at Calroy Health Sciences have discovered, putting a tremendous amount of work and financing into studying the effects of the uniquely-developed Cartigenix-HP. Not only that, increased joint space at the end of the trial was clearly visible via radiography, and 90% of the intervention group did not need any "rescue" pharmaceutical medication at the end of the 90 day period (compared with only 20% of the placebo group) and this effect was sustained beyond the end of the trial. I have to say, I am impressed and excited about the potential for this new product to help my patients and I am thinking about other applications like OA prevention and osteoporosis!
