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.

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

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

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

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.

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! Listen in to find out more. ~ DrKF

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. It’s a conversation you won’t want to miss! ~DrKF

Hidden Mitochondria Problems Are Accelerating Your Age & Draining Your Health

What if the key to reversing chronic disease, slowing cognitive decline, and boosting energy lies in the tiny powerhouses inside your cells—and we’ve finally found a way to protect them?

We know mitochondria power our cells, but did you know they also create oxidative stress as they generate energy? Protecting mitochondrial health is critical—but most antioxidants can't reach inside the mitochondria where protection is needed most—until now. MitoQ, a scientifically advanced, mitochondria-targeted antioxidant developed by visionary researchers in New Zealand penetrates mitochondria up to 90%, offering protection where it's needed most.

In this episode with Dr. Siobhan Mitchell, we dive into how MitoQ is transforming the way we tackle chronic disease, inflammation, and cognitive decline. From improving heart health to supporting brain function, MitoQ is changing the game. It’s something I’m using personally and recommending to most of my patients. Listen in to discover how this powerful tool can help you support your patients at the cellular level—before symptoms even appear. ~DrKF

A Fresh Take on Exposomics: Resiliency Factors That Offset Environmental Risks
It’s very difficult (often impossible) to completely avoid many of the environmental toxins that can cause harm - like air pollution and forever chemicals that contaminate our water and food supply. But Drs. Bob and Rosalind Wright at Mount Sinai have a hopeful solution to this dilemma. They are pioneering the study of “resiliency factors,” not just “risk factors,” that can offset the risks of harmful exposures. It’s a fresh and welcome take on exposomics that I am very excited to share with you. For instance - did you know that omega-3 intake during pregnancy can protect against the development of asthma in the child, even if the child is exposed to known risk factors for asthma? Or that positive relationships (ones that create a sensitive, positive, caregiving environment) have been shown to potentially mitigate the effects of environmental toxins? As a practitioner, I am always looking to empower patients with real solutions to the health challenges we inevitably face and I hope you enjoy this conversation as much as I did. ~DrKF
