GLP-1 receptor agonists have transformed the way we approach obesity and metabolic disease. The results can be remarkable. But as their use continues to expand, I think we need to be asking a bigger question: what does long-term metabolic health…
What stayed with me across these conversations was just how much the lens of longevity medicine is expanding. We explored exciting new science, emerging technologies, and powerful clinical insights, but we also found ourselves asking deeper questions about what it…
As functional medicine clinicians, we often spend our careers helping patients reverse years, sometimes decades, of accumulated dysfunction. But what if some of the most powerful opportunities to influence lifelong health occur long before symptoms ever appear? What if they…
The skin has long been treated as a cosmetic concern, but emerging science suggests it’s much more than that. As our largest organ, the skin serves as a critical barrier between us and the outside world, yet it also plays…
Menopause is one of the most significant biological transitions a woman will experience, yet the way we’ve defined and managed it has changed remarkably little over the last century. For many women, the conversation still revolves around hot flashes and…
Muscle is having a moment—and for good reason. As functional medicine clinicians, we recognize that muscle isn’t just about strength or athletic performance. It’s central to metabolic health, resilience, mobility, healthy aging, and longevity. Yet resistance training can still feel…
This was a conversation our team had been looking forward to for a while. We came in with a lot of questions, especially around those chronic, persistent cases that don’t respond the way we expect. Dr. Richard Horowitz, one of…

Cardiovascular disease is the number one threat to healthspan and longevity. But, aging in women doesn’t follow the same trajectory as it does in men. Alongside perimenopause, as the protective effects of estrogen wane, dyslipidemia, metabolic dysregulation, and weight gain…
This was a particularly meaningful conversation for me. I’ve been referencing Dr. Bill Harris’s work for many years, so it was a real privilege to sit down with him and explore these topics together. What struck me most is the…
It feels like every patient walking into our offices right now is hearing the same message—eat more protein. But maybe the more important question isn’t just how much protein someone is eating, but whether their gut can actually digest and…
More and more in practice, we’re working with what I often think of as “tough guts,” patients arriving on increasingly restricted diets, afraid to expand foods because nearly everything seems to trigger symptoms. A big part of our work now…
I was really excited to sit down with Dr. Robert Lustig for this conversation. If you’ve ever thought seriously about sugar, fructose, or metabolic health, his work has probably shaped your thinking in some way. He’s also deeply outspoken, and…
I just had a really fascinating conversation with the scientists at Sōlaria biō—Mark Charbonneau and Alicia Ballok—about a line of research that genuinely made me stop and rethink how we approach bone health. We talked about their journey from isolating…
This isn’t the podcast I expected to release this month. Not even close. But, in the wake of the most recent release of Epstein-related documents, things took a turn. In the face of what is such a colossal abuse of…
This was an energizing and important conversation with Dr. Gabrielle Lyon. Her ability to connect muscle health with metabolic stability, aging, and even our current misunderstanding of obesity lit up something for me. The idea that intramuscular adipose tissue may…
Exosomes are having a moment right now, but this is the first time I’ve felt like I was able to sit down and really unpack what matters, the science behind them, the variability in sources, and why not all exosome…
The oral microbiome belongs squarely in the functional medicine toolkit, and my conversation with Staci Whitman, DMD, IFMCP, makes that more clear than ever. As a board-certified pediatric dentist and co-founder of the Institute for Functional Dentistry, Staci is reshaping…
