The Dr. Gabrielle Lyon Show

You've probably worried that the glyphosate on your bread is slowly harming you. The evidence points somewhere far less obvious and far more fixable.
In this solo episode, Dr. Gabrielle Lyon discusses:
Why the real concern isn't cancer risk from your toast, but glyphosate's effect on your gut, where it can act like a selective antibiotic, hitting beneficial bacteria while sparing the harmful ones
Where the residue concentrates (grains and legumes like oats up to 1100 ppb) and why meat, milk, and eggs carry negligible amounts, so your organic dollars belong on oats and bread, not chicken
The three NHANES analyses linking higher glyphosate to weaker grip strength and greater sarcopenia risk, and why protein and resistance training matter more than agonizing over parts per billion
How switching to organic staples cuts urinary glyphosate by 71% in six days, and why "detox" products aren't the answer
Why banning glyphosate isn't a clean win, the leading alternative, 2,4-D, was a component of Agent Orange

Understanding where glyphosate genuinely matters lets you stop worrying about the wrong foods, spend smarter at the grocery store, and protect the two things that move the needle: your gut and your muscle.

Most people think low back pain means something is wrong with their back. It's usually the hips — and the fix often starts on your living room floor.
In this episode, Dr. Gabrielle Lyon sits down with Dr. Kelly Starrett and Juliet Starrett, JD to discuss:
Why 100% of the people who fly across the country to get a consult for stubborn low back pain are missing hip extension, and how to test yours with the couch stretch
The "injury vs. incident" framework that tells you when pain needs a doctor and when you can manage it yourself
How 20–30 minutes of floor sitting each evening restores the range of motion you thought you'd lost to age
Why mobility is the missing third leg of the longevity triangle that roughly 90% of people skip

By the end, you'll have a simple, no-equipment way to move without pain and keep the strength and mobility that let you do what you love as you age.

Over 500 published papers stand behind one of the internet's most popular peptides, but fewer than 30 of the humans studied are in them. Dr. Gabrielle Lyon separates the molecule from the marketplace so you can tell real evidence from good marketing.
In this solo episode, Dr. Gabrielle Lyon discusses:
Why BPC-157's "mountain of evidence" collapses to a 99.7% animal-to-human ratio - 544 papers, but fewer than 30 humans across three uncontrolled pilot trials
How to place any peptide on the spectrum from FDA-approved (GLP-1s like semaglutide) to investigational to compounded, and why "GLP-1s work, so peptides work" is a trap
What the FDA quietly did in April 2026, and why removing a dozen peptides from its safety-concern list was driven by policy pressure, not new safety data
The 4 questions to run on any peptide before you inject level of evidence, what the study measured, where it's sourced from, and whether it's banned in tested sport
Why the "boring work", resistance training, protein-anchored nutrition, and real recovery beat almost anything in a vial

If something is going into your body through a needle, the standard has to be higher than three words on a label that say "research use only." This episode gives you the framework to protect yourself before spending a dollar or taking a shot.

Everyone on a GLP-1 is watching the scale; almost no one is watching their bones. Bone loss isn't an inevitable part of aging; it's a reversible signal that something deeper is going wrong, and it starts far earlier than most people are ever warned.
In this episode, Dr. Gabrielle Lyon sits down with Dr. Douglas Lucas, a former Stanford-trained orthopedic surgeon turned bone-health specialist, to discuss:
Why bone loss begins around 45 during perimenopause, not 50, and why waiting for your first DEXA scan at 65 is far too late to prevent it
The blind spots in the standard DEXA scan: a scan-to-scan margin of error near 6% and no read on bone quality, only quantity
Bone turnover markers (CTX and P1NP) you can test from blood to see whether you're building or breaking down bone in real time
Why the "protein is bad for bones" and "alkalize your diet" beliefs are myths and why protein, minerals, and adequate calcium matter more than calcium alone
What rebuilds bone at home: resistance training, real impact like heel drops, and vertical vibration plates used ~10 minutes a day

Understanding your bones as a living, changeable organ system means you can catch loss early, measure it honestly, and reverse the trajectory, instead of accepting decline as your fate.

You've eaten red meat your whole life, so why does a steak dinner suddenly leave you covered in hives at 1 AM? A single Lone Star tick bite can rewire your immune system into a delayed allergy to red meat, and most people (and even their doctors) never connect the two.
In this solo episode, Dr. Gabrielle Lyon discusses:
Why alpha-gal reactions are delayed 2–6 hours after eating meat, and how that delay causes ER visits to be repeatedly misdiagnosed
How your blood type changes your risk (type A and O are higher-risk; type B appears protected) and why a mismatched transfusion has proven fatal
The simple alpha-gal IgE blood test to ask for, and what the numbers mean
The hidden sources beyond food: gelatin, vaccines, heparin, thyroid meds, and even heart valves
The tiered treatment approach that resolves symptoms in about 80% of patients on meat-avoidance alone

Learn to recognize a condition that's increasingly common yet widely missed, so if it's happening to you, you'll know exactly what to test for and how to get your life back. It's not all in your head.
