The Dr. Gabrielle Lyon Show

The longevity world has convinced a generation of women that protein is shortening their lives. The science says they've got it backwards and the people hurt most are the ones who need protein most.
In this episode, Dr. Gabrielle Lyon breaks down the protein-and-longevity fear, steelmans the strongest case against protein, then walks through what the evidence shows:
The RDA (0.8 g/kg) is a deficiency floor, not a target, the intake one camp calls "dangerously high" is what federal guidelines and expert groups now recommend (1.2–1.6 g/kg)
The IGF-1–cancer link is tiny (a 3–11% risk bump vs. smoking's 1,000–2,000%), and the IGF-1–mortality curve is U-shaped: the lowest levels carry ~40% higher death risk
Sarcopenia roughly doubles death risk (3.5× with frailty) and perimenopause stacks anabolic resistance on top, exactly when women are told to fear the foods that defend them

By the end, you'll understand the mTOR and IGF-1 science well enough that nobody online can scare you off your own dinner, plus a simple Monday-morning plan: adequate protein, front-loaded, built on minimally processed foods, with heavy lifting to match.

The parasites most Americans think of as a tropical problem are already here; showing up as fatigue, asthma, and gut issues that standard tests keep calling "normal." An estimated 1 in 20 people may carry one and never know it.
In this episode, Dr. Gabrielle Lyon sits down with Dr. Peter Hotez, a tropical-medicine physician and vaccine scientist, to discuss:
Why toxocariasis, a worm shed by household dogs and cats, may affect 5–6% of the U.S. population, with larvae migrating through the lungs and brain
Why standard PCR panels come back negative and which specific tests (antibody, fecal, eosinophil count) to ask for
How to lower your risk at home, from deworming pets on a vet schedule to knowing which symptoms warrant a targeted test
Why the popular "worm therapy for autoimmune disease" idea has the relationship backwards, worms are a leading driver of IBD and asthma, not a cure

Whether you've been told your labs are fine but still feel off, this conversation gives you a clear, evidence-based framework for what to test for and how to protect your family from infections hiding in plain sight.

You might think microplastics are just an environmental nuisance that passes through your body, but the latest tissue studies tell a very different story. As a physician, Dr. Gabrielle Lyon breaks down where the science lands, past both the fear-mongering and the dismissiveness.
In this solo episode, Dr. Gabrielle Lyon discusses:
Why over 58% of patients in a landmark NEJM study had plastic embedded in their arterial plaque and the 4.5x higher risk of heart attack, stroke, and death that came with it
How microplastics act as a "Trojan horse," carrying endocrine-disrupting chemicals into your blood, testes, brain, and reproductive tissue
Why perimenopause and menopause are an especially vulnerable window for plastic-driven hormone disruption
The five low-cost "Lyon Protocol" rules to cut your exposure, starting with never microwaving plastic and letting food cool before you store it

This matters because you don't need to overhaul your life or wait twenty years for perfect data to protect your cellular health; you just need the handful of small, automated decisions that move the needle on your metabolic and hormonal baseline.

You've been told that 10,000 steps a day is enough to keep you healthy but when it comes to your bones and your muscles, walking falls short, and the science explains exactly why. The real drivers of strength, bone density, and lasting health are load, intensity, and resistance, not just movement.
In this episode, Dr. Gabrielle Lyon sits down with Dr. Alyssa Olenick, a PhD in exercise metabolism and ultramarathoner who blends endurance and strength training, to discuss:
Why the "interference effect," the fear that cardio cancels your strength gains, is overblown for almost everyone, and what causes the carryover fatigue
How most women train too lightly, believing they're at a 9 out of 10 when they're closer to a 5, and never trigger real muscle adaptation
Why estrogen is not the primary driver of muscle, resistance training is, and what that means through the menopause transition
The early warning signs of low energy availability, including cycle changes that show up long before a missed period, and the rapid bone loss that follows
How to structure strength, power, and cardio together, and fuel it properly without sabotaging recovery

You'll walk away knowing how to train for strength, power, and bone density that lasts and why being undertrained, not fragile, is the real problem for most women.

You were told your testosterone is "normal" so why do you still feel exhausted, weak, and off? The number on your lab report was never built for you, and your own genetics may be the reason it doesn't match how you feel.
In this solo episode, Dr. Gabrielle Lyon discusses:
Why the standard 300–1000 ng/dL range ignores your age, comorbidities, and genetics, and why two men with identical labs can feel completely different
How CAG repeats determine whether your body "catches" the testosterone you produce, meaning you might need 400 to feel great while someone else needs 800
Why the 80-year-old fear that testosterone fuels prostate cancer is built on a single flawed 1941 study, and what the androgen saturation model proves instead
How everyday endocrine disruptors BPA in receipts, phthalates in personal care, atrazine in tap water quietly lower your testosterone even when you eat clean and train hard
The correct AUA testing protocol your doctor may be skipping: two early-morning, fasted measurements plus actual symptoms, not one afternoon blood draw

Understanding how your own body uses testosterone lets you walk into your doctor's office armed with facts instead of frustration and stop being told you're "fine" when you don't feel it.
