Beyond Systems Biology: The Missing Link in Functional Medicine | Ep 402

Author: Erin Holt March 17, 2026 Duration: 51:35

So many people bounce between specialists, run every lab under the sun, and still feel stuck in the same symptom loop. What if the problem isn’t missing data, but the way we’re looking at the body in the first place?

In this episode, Erin is giving you an exclusive sneak peek inside the Funk’tional Nutrition Academy Open House, where she breaks down her model of intuitive functional medicine.

Erin explains why healing requires more than labs and protocols, how nervous system patterns shape our symptoms, and why self-trust might be one of the most overlooked pieces of root cause care.

In this episode:

  1. Why chronic illness is often a breakdown in communication between body systems instead of a single root cause
  2. How practitioners can help clients rebuild self-trust and reconnect with their body’s healing intelligence
  3. The surprising role of interoception and how trauma, stress, and conditioning can distort how we interpret signals
  4. Erin’s framework for combining lab data, nervous system work, and intuition in root cause care
