In this episode of The Lisa Fischer Said Podcast, Lisa Fischer sits down with Reed Davis, founder of Functional Diagnostic Nutrition (FDN), to challenge everything you think you know about functional medicine and “root cause” healing. Reed shares his journey from environmental law to health detective, explains why symptoms are not the problem—but signals of deeper metabolic chaos—and breaks down his HIDDEN and D.R.E.S.S. frameworks for restoring health without drugs. They dive into functional lab testing, supplement skepticism, thyroid disorders, chronic fatigue, hives, ADHD, environmental toxins, and why personalized, upstream investigation matters more than diagnoses. This conversation is a must-listen for anyone frustrated with normal labs, endless prescriptions, or one-size-fits-all wellness advice.
