We are living through one of the most significant shifts in medicine in generations, and most people don’t fully understand what it means. Dr. Christle Guevarra joins me to zoom out on the entire GLP-1 landscape; from the drug’s origins as a modest diabetes treatment in 2005 to today’s third-generation medications still moving through clinical trials, and what all of it means for the future of obesity, performance, and longevity.

The moment you decide to show up publicly, you open the door to opinions from people who would never say those things to your face. Dominique Sachse, journalist, author, and content creator who has lived her life on camera for over three decades, gets honest about what it costs to put yourself out there, why online cruelty is a psychology problem more than a content problem, and how “Teflon Dom” developed the thick skin to let none of it redirect her.

Only nine scientists were asked to advise on the 2025 Dietary Guidelines for Americans, and Dr. Tom Brenna was one of them. In this conversation, he pulls back the curtain on how dietary guidelines are actually made, why the process has never been the same twice, and what it was like to watch a decades-old saturated fat recommendation get carried forward despite a lack of evidence supporting it at the level of total mortality. This is the dietary guidelines conversation the internet has been missing: straight from someone who was actually in the room.

In a world flooded with conflicting health advice, how do you actually figure out what’s true? Dr. David Allison, one of the most rigorous scientific minds in obesity and nutrition research, shared the exact framework he uses to evaluate evidence, from peer-reviewed trials to podcast recommendations to AI-generated summaries. He explains the difference between trusting science as a process and trusting individual studies, why most nutrition epidemiology functions more like advertising than research, and how ordinary people can build a reliable filter for health claims without a PhD.

Up to 70% of dementia may be preventable, so why aren’t more people talking about what actually drives cognitive decline? In this episode, I’m with Dr. Tommy Wood, neuroscientist and author of “The Stimulated Mind,” to explore the lifestyle levers that protect your brain across a lifetime. Learn how white matter hyperintensities develop and whether they can reverse, what MCTs and ketones actually do for a glucose-starved brain, and why social connection may be the most underrated variable in cognitive aging. What is the one change you could make today that would most protect your brain tomorrow?

Metabolic flexibility is your body’s ability to efficiently burn fat or carbohydrate depending on demand, may be one of the most important and least understood markers of long-term health. In this episode, I’m with Dr. Martin Gibala to explore the emerging science of Fat Max, why mitochondrial quality is central to both performance and longevity, and how sprint interval training produces comparable mitochondrial adaptations to traditional endurance work in a fraction of the time. Could the key to better metabolic health be less about the hours you log and more about how hard you’re willing to push?

The most decorated woman in motorsports history will tell you she feared losing far more than she loved winning, and that fear is exactly what drove her to the top. In this episode, I’m with racing legend Danica Patrick to unpack the psychology of elite performance, from the “blind faith” that carried her through two decades of racing to the nervous system conditioning she built starting at age 10. What would be possible for you if you learned to channel pressure instead of escaping it?

I’m joined by Dr. Heather Hirsch to debunk the persistent myths surrounding hormone replacement therapy and explain why the 2002 Women’s Health Initiative data was so widely misinterpreted.

Whether you are in perimenopause or well past the ten-year window, you'll learn how to navigate personalized dosing and clinical data to reclaim your vitality and extend your health span.

Male fertility is declining, and most men have no idea why.

In this episode of The Dr. Gabrielle Lyon Show, Dr. Gabrielle Lyon sits down with Dr. Michael Eisenberg, Director of Male Reproductive Health at Stanford University and Chief Medical Advisor of SwimClub, to break down what truly determines sperm health and reproductive success.

They discuss:

1. How metformin, GLP-1 medications, testosterone therapy, and anabolic steroids affect male fertility
2. Why sperm count is a powerful biomarker for long-term health and longevity
3. The role of sleep, muscle mass, exercise, diet, marijuana, and environmental toxins like microplastics
4. Whether platelet-rich plasma, or PRP, can help severe male infertility
5. Daily habits that quietly reduce a couple’s chances of conceiving

If you care about fertility, hormones, metabolic health, or the future of men’s health, this conversation is essential.

Self-doubt holds more people back than lack of skill or intelligence.

In this episode, Dr. Gabrielle Lyon sits down with Dr. Shadé Zahrai to explore the science of confidence, self-trust, and peak performance. They break down why confidence comes after action, how self-image shapes success, and the four psychological drivers that determine whether you thrive or stay stuck.

You will learn how body language influences perception, why high performers plan for failure, how perfectionism leads to burnout, and the subtle communication habits that undermine credibility. Most importantly, you will discover how to build what Dr. Zahrai calls Big Trust so you can back yourself before you feel ready.

If you struggle with overthinking, imposter thoughts, or feeling capable but not fully confident, this conversation will give you practical tools to change how you show up.
