The Dr. Gabrielle Lyon Show

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:
How metformin, GLP-1 medications, testosterone therapy, and anabolic steroids affect male fertility
Why sperm count is a powerful biomarker for long-term health and longevity
The role of sleep, muscle mass, exercise, diet, marijuana, and environmental toxins like microplastics
Whether platelet-rich plasma, or PRP, can help severe male infertility
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.

In this episode, Dr. Gabrielle Lyon sits down with Dr. Donald Layman, one of the world’s leading protein researchers and a key contributor to the newly released U.S. Dietary Guidelines. They explore why the old food pyramid failed, how nutrition science became driven by ideology instead of evidence, and what the updated guidelines finally get right about protein, fats, and carbohydrates. Dr. Layman explains why the long-standing protein recommendation of 0.8 g/kg was never intended for optimal health and how higher protein intake supports body composition, metabolic health, and nutrient adequacy.
The conversation also dives into controversial topics including saturated fat, carbohydrate tolerance, animal versus plant protein, and the limitations of epidemiology in nutrition research. Gabrielle and Dr. Layman discuss how dietary guidelines shape school lunches, hospitals, and public institutions, and why a protein-first framework empowers individuals to make better nutrition decisions, especially as we age. This episode offers a clear, science-backed roadmap for understanding modern nutrition — cutting through misinformation and outdated dogma to focus on strength, longevity, and real-world application.

In this solo episode, Dr. Gabrielle Lyon shares the deeper mission behind The Forever Strong PLAYBOOK and the philosophy that has guided her work for decades.
This conversation is not about trends, quick fixes, or aesthetics. It is about building strength as a lifelong responsibility and understanding why skeletal muscle is the foundation of health, resilience, and independence across the lifespan.
Dr. Lyon introduces the Forever Strong ethos and walks through the four foundational pillars that support a strong life: how to think, how to eat, how to move, and how to recover. She explains why information alone does not change behavior and why clarity, discernment, and disciplined action are the true drivers of lasting health.
Throughout the episode, Dr. Lyon challenges conventional narratives around aging, nutrition, exercise, and recovery. She reframes longevity through the lens of muscle span, the length of time a person lives with healthy, functional skeletal muscle, and explains how physical strength supports metabolic health, emotional regulation, and cognitive resilience.
This episode is an invitation to step out of confusion and into a clear framework for living with intention. Strength is not something we inherit. It is something we build, choice by choice, day by day.
