The Dr. Gabrielle Lyon Show

Blowing four times the legal limit on a breathalyzer usually means one thing, but in 2015, a judge dismissed a DWI because the driver's own gut was fermenting alcohol from an ordinary carb-heavy dinner. It's called auto-brewery syndrome, and the fuel it runs on is the same load your muscle is supposed to be clearing from your blood.
In this solo episode, Dr. Gabrielle Lyon discusses:
How gut yeast overgrowth turns everyday carbs like pasta, bread, and rice into ethanol that registers as real intoxication, brain fog, dizziness, and all
The specific risk factors that open the door: dysbiosis, SIFO, repeated antibiotic use, and poorly controlled diabetes or fatty liver
The three-part protocol to correct it, reduce the yeast burden, remove the carbohydrate fuel, and rebuild the microbiome, plus the carbohydrate challenge test, most doctors never run
Why skeletal muscle is your body's primary site for clearing blood sugar, and how an under-muscled body drifts into the same insulin-resistant, dysbiotic state that lets fermentation take hold

Whether or not you'll ever face this rare diagnosis, you'll walk away understanding that gut health and muscle health share one supply chain and that defending your muscle is how you starve the problem at its root.

Most people chase happiness as a feeling and wait for certainty before making big decisions, and both instincts quietly backfire. Dr. Arthur Brooks joins Dr. Gabrielle Lyon to break down what happiness is and how to act on it.
In this episode, Dr. Gabrielle Lyon and Dr. Arthur Brooks discuss:
The three "macronutrients" of happiness - enjoyment, satisfaction, and meaning, and why pursuing pleasure alone leads to detox, not happiness
A usable rule for any hard decision: aim for roughly 80% excitement, 20% fear, and near-zero "deadness" once you have about 80% situational awareness
Why solo pleasures don't stick if you're doing it alone, you're probably doing it wrong, and how enjoyment requires people plus memory
How GLP-1s, SSRIs, and hormonal shifts can dull motivation, reward, and desire, and why knowing this gives you power over it
Simple tech protocols: phone-free first hour, meals, and last hour that protect oxytocin, meaning, and connection

Understand happiness as something you build rather than something you wait to feel, and you walk away with concrete tools to decide better, connect deeper, and stop mistaking achievement for love.

You might think the number dropping on the scale is the whole win, but on a GLP-1, a meaningful share of what you're losing may be muscle, not fat, and the fiber that's supposed to help can quietly make things worse.
In this solo episode, Dr. Gabrielle Lyon discusses:
Why 25–40% of the weight lost on GLP-1 medications can be lean mass, and how to protect your muscle with adequate protein (1.2–1.5 g/kg) and resistance training
The GLP-1 fiber paradox and why these drugs need fiber to work, but make it hard to tolerate, and why 40–70% of patients hit GI side effects like bloating and constipation
When to fiber max vs. fiber mine, plus how to reintroduce fiber gradually so you get the gut benefits without the bloat, bezoars, or obstruction risk

Get this balance right, and you keep your muscle, calm your gut, and let the medication do its job instead of ending up bloated, constipated, and quietly losing strength.

You'd think fear is what stops you from doing hard things. At 25, with zero rowing experience, Taryn Smith crossed the Atlantic alone. 3,000 miles, 46 days, and I learned that the fear was never the obstacle. It was the signal she was finally in the right place.
In this episode, Dr. Gabrielle Lyon and Taryn Smith discuss:
Why fear is a "metric of success," not a stop sign, and how to train yourself to move toward discomfort instead of away from it
How food becomes visible performance fuel when you're the only engine, and how to preserve muscle on limited calories using protein and daily amino acids
The "long-term optimist, short-term realist" mindset that carries you through a slog with no end in sight
The post-achievement crash nobody warns you about, and why the low after a big win is predictable

Whether or not you'll ever touch an oar, you'll walk away with a portable mental framework for facing anything you've been avoiding, and a clearer sense of who you are when no one's watching.

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.
