27. Out of Overdrive: Calming Your Nervous System to Heal Your Gut

December 17, 2025

In Part Two of her “worrier’s gut” series, Lisa Garrett dives even deeper into the connection between anxiety, sympathetic overdrive, and digestive chaos. If you’re the type who can’t shut off your brain, sleeps lightly (or not at all), chews gum, taps your foot, or constantly feels “on,” this episode is your roadmap back to balance.

Lisa explains what happens when the body gets stuck in fight-or-flight — how sleep changes, appetite shifts, digestion slows, hormones wobble, and hair loss, stomach aches, or weight changes can suddenly appear. She also opens up about her own current season of high stress as she navigates her dog Leo’s cancer diagnosis, and how that sympathetic overdrive immediately affected her own gut.

Then, she shares exactly how to support your parasympathetic nervous system through movement, daily rituals, intentional eating, and calming food choices. From what to avoid (processed foods, raw salads, heavy fibers) to what your body actually needs (warm, cooked foods, grounding protein, gentle digestion), Lisa provides real, practical guidance for anyone trying to get out of overdrive and back into rest, repair, and relief.
