The Dr. Gabrielle Lyon Show

Heart disease is the leading cause of death for women—yet it's still treated like a man’s disease. In this powerful conversation, Dr. Martha Gulati, a cardiologist and pioneer in women’s cardiovascular health, exposes the systemic gaps that leave women underdiagnosed, undertreated, and often unheard. Together, we unpack the critical differences in how heart disease presents in women, why standard diagnostic tools fall short, and what every woman needs to know about risk factors like pregnancy complications, hormone therapy, statin use, and even environmental exposures. Dr. Gulati also reveals the truth behind hormone therapy myths, explains how soft plaque really forms, and why fitness should be considered frontline prevention.

You’ll learn:

• Why women’s heart symptoms are often mistaken for anxiety
• What tests to ask for to asses your risk of heart disease
• How statins, hormone therapy, and fitness interact with risk
• What the new “Prevent" risk score includes—and why it matters
• Why women get more benefits from exercise than men
• How pollution, stress, and pregnancy complications shape long-term risk

Whether you’re in your 20s or postmenopausal, this episode will empower you to take charge of your heart health, ask better questions, and get the care you deserve.

Muscle health isn’t just about how much protein you eat—it’s about how your body uses it. And for people with obesity or advancing age, that process can become less effective, even with optimal nutrition.

In this episode, I am joined by Dr. Nick Burd, one of the world’s leading researchers in muscle metabolism, to unpack the concept of anabolic resistance—when muscle doesn’t respond normally to protein and/or exercise. Together, we explore how aging, obesity and even the way foods are combined on your plate can impact muscle remodeling, recovery, and growth. Dr. Burd also shares why plant-based proteins often fall short, why protein efficiency matters more than quantity, and how endurance and resistance training affect nutrient use differently.

You’ll learn:

• What anabolic resistance is—and why it matters
• How to improve protein efficiency and muscle quality over time
• Why food matrix, and timing can change your results
• Key differences in nutrition strategies for endurance vs. strength athletes

Whether you're focused on longevity, performance, or helping someone break through a plateau, this episode delivers the research-backed information you’ve been looking for.

Who is Dr. Nick Burd?

Dr. Nick A. Burd is a muscle-metabolism scientist and professor at the University of Illinois at Urbana-Champaign, where he leads the Nutrition & Exercise Performance Research Group. Originally from the Midwest, he trained under renowned experts around the world before focusing his research on how protein and exercise influence muscle health across the lifespan. His work uses advanced tracer methods and muscle biopsies to explore optimal protein intake, plant vs. animal protein quality, and strategies to combat anabolic resistance.

In this episode, I sit down with Dr. David Klurfeld—longtime USDA scientist and one of the few insiders to publicly challenge the WHO's classification of red meat as a carcinogen. We go deep into the flawed evidence behind the infamous 2015 IARC report, why nutritional epidemiology often fails to prove causality, and how a small group of researchers helped shape global policy with low-quality science. If you've ever felt confused about meat, saturated fat, or dietary guidelines, this conversation will help you think critically about what “counts” as evidence—and who gets to decide.

We cover:

• Dr. Klurfeld’s personal journey and lessons from a career in public health
• Why the 2015 IARC red meat classification was based on weak and inconsistent evidence
• How observational studies and “allegiance bias” mislead nutrition science
• The politics of dietary guidelines and the role of the USDA and WHO
• What the media got wrong—and why red meat remains a nutrient-dense food

Whether you're a clinician, dietitian, or simply trying to make better nutrition decisions, this episode is a powerful reminder that bias, groupthink and weak data can distort science and mislead the public. We need to be discerning about the nutrition and health advice we follow.

Who is Dr. David Klurfeld?

Dr. David Klurfeld is a nutritional scientist and former National Program Leader for Human Nutrition at the USDA’s Agricultural Research Service. He also served as Professor and Chair of Nutrition and Food Science at Wayne State University and Associate Editor of The American Journal of Clinical Nutrition. He has authored more than 200 scientific publications and was one of 22 experts invited to the 2015 IARC working group on red meat and cancer. He is a longtime advocate for scientific integrity in public health policy.

What if your biggest challenge isn’t motivation but missing structure? In this episode, I sit down with Brian Johnson to unpack the science and philosophy of lasting behavior change. We explore the power of ancient wisdom, stoicism, and the neuroscience of excellence, and why most wellness apps fail to deliver real transformation.

Brian shares his personal journey from startup success to creating a global movement around character, discipline, and identity-based habits. We talk about the science of anti-fragility, how muscle mirrors virtue, and why the gap between who you are and who you could be is the true source of suffering. Whether you're a high performer or someone who wants to stop breaking promises to yourself, this conversation will help you build the structure to show up as your best—no matter the circumstance.

What You’ll Learn:

• Why most behavior change fails—and what the science says works
• The philosophy of Areté: how to close the gap between potential and action
• How ancient stoicism aligns with modern recovery, resilience, and muscle
• Why building muscle is a metaphor (and mechanism) for building character
• The true definition of anti-fragility—and how to train it

If you're ready to bridge the gap between knowing and doing, this episode is the roadmap you've been looking for.

When it comes to performance, more isn’t always better. In this episode, I sit down with conditioning expert Joel Jamieson to explore the science of recovery, aerobic fitness, and how to use heart rate variability (HRV) to train smarter. They dive into why elite athletes recover so quickly, the long-term value of zone 2 training, and how HRV reflects your resilience—not just your readiness. Joel shares lessons from two decades of working with fighters, Olympians, and NFL players, along with powerful insights from his own cardiovascular health journey. Whether you’re a high performer or simply want to live longer and stronger, this episode is packed with practical takeaways.

In this episode, you’ll learn:

• What HRV actually tells you—and what it doesn’t
• Why aerobic fitness is one of the strongest drivers of recovery and longevity
• The surprising downside of too much strength training
• How to monitor training load and avoid overtraining
• Why lifestyle stress matters more than your workout

This episode will change the way you think about training—and reveal why recovery deserves a central role in your performance strategy.

In this episode, I’m joined by Dr. Ty Beal—global nutrition researcher and Senior Technical Specialist at the Global Alliance for Improved Nutrition (GAIN)—to uncover the hidden epidemic of micronutrient deficiencies worldwide. From food access and affordability to ultra-processed diets and nutrient bioavailability, we explore how modern food systems are failing billions and what needs to change to truly make the world healthier.

We cover:

• Why 3 billion people can’t afford a healthy diet—and how that affects nutrient status
• The most common global and U.S. micronutrient deficiencies (and why they’re often overlooked)
• Why women and children are especially vulnerable during pregnancy, infancy, and adolescence
• The role of ultra-processed foods in displacing nutrient-rich options
• How bioavailability, anti-nutrients, and the “food matrix” impact your real nutrient intake
• Why plant-based diets aren’t always safer—and the hidden risks of nutrient shortfalls
• The science behind biofortification, food system reform, and why animal-source foods stil matter
• What the U.S. gets wrong about food guidelines, global trade, and nutritional equity

Whether you care about maternal health, child development, or just making better nutrition decisions, this is a vital conversation about nutrient density, food justice, and global health.

Who is Dr. Ty Beal?

Dr. Ty Beal is a Senior Technical Specialist and global nutrition scientist at the Global Alliance for Improved Nutrition (GAIN) where he leads research on global food systems, nutrient inadequacy, and diet quality. His work bridges science and policy to help address the world’s most pressing nutrition challenges—especially among vulnerable populations. He’s published extensively on micronutrient gaps, ultra-processed foods, and global dietary patterns, and is one of the most cited voices on nutrition equity in developing nations.
