Coach Debbie Potts - The Gut-Brain Connection & Parkinson’s: Martha Carlin’s Mission to Find a Cure
by Kevin Danielson March 06, 2025
In this episode, we dive deep into the groundbreaking research of Martha Carlin, a visionary systems thinker and citizen scientist dedicated to uncovering the root causes of Parkinson’s disease through the gut microbiome. After her husband, John, was diagnosed with early-onset Parkinson’s in 2002, Martha embarked on a mission to connect the dots between gut health, environmental toxins, and chronic disease.
When most people think about circadian rhythm, they think about sleep. But your circadian rhythm is much more than a sleep-wake cycle. It is a master biological timing system that influences nearly every aspect of health, including metabolism, immune function, hormone production, digestion, detoxification, and even how your gut microbes behave.
Let’s be completely honest: When was the last time you actually looked inside the bowl before you flushed? If your immediate reaction is to cringey-laugh and say, "Ugh, never," you are throwing away the single most valuable health report your body produces daily.
A chronic diagnosis is almost always delivered as a final sentence, completely devoid of hope. In the conventional medical model, patients are given a label—whether it’s Parkinson’s, Alzheimer’s, or chronic fatigue—and told, “There is no cure. This is progressive. Take this pill.”
The path to vibrant health is rarely a straight line. Often, it takes a deeply personal disruption to force us to look at the human body through a completely different lens. For Martha Carlin, a former corporate auditor and turnaround expert, that disruption came in 2002 when her healthy 44-year-old husband, John, was diagnosed with Parkinson’s disease.
