Episode Details

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.
