Healing Horizons: Functional Medicine for Burnout, Hashimoto’s & Metabolic Health After 40 with Peggy Moore

On this episode of Healing Horizons, we get practical about fatigue, brain fog, stubborn weight, poor sleep, and “normal labs” that don’t explain why you still feel off. Peggy Moore—a former ICU nurse turned functional medicine practitioner—walks through how she addressed her own Hashimoto’s, insulin resistance, and gut issues, then built the Thrive After 40 method for busy women. We unpack labs beyond basics, root-cause thinking, sustainable nutrition, stress regulation, and realistic routines that fit real lives. If you’ve been dismissed with “that’s just aging,” this conversation offers a direct, evidence-aware path to ask better questions and take next steps safely with your clinician.

About the guest:

Peggy Moore spent 25+ years in critical care nursing. After personal burnout and unresolved symptoms, she shifted to functional medicine, focusing on metabolic health, thyroid/autoimmune care, gut repair, sleep, and stress recovery for women 40+. She now helps clients rebuild energy, mood, and metabolic resilience with stepwise, test-guided plans.

Key takeaways :

• Fatigue that requires constant caffeine is a signal, not a lifestyle; investigate sleep quality, cortisol rhythm, iron/B12, thyroid panel, insulin resistance, and inflammatory markers with your clinician.

• “Normal” basics can miss issues; discuss a full thyroid work-up (TSH, free T4/T3) and, when clinically appropriate, thyroid antibodies to evaluate autoimmune activity.

• Metabolic changes can appear years before a diabetes diagnosis; track fasting glucose, HbA1c, and—if appropriate—fasting insulin/HOMA-IR to spot trends early.

• Gut health matters: ultra-processed foods and certain additives may aggravate symptoms; prioritize whole foods, protein, fiber, and diverse plants while noting personal tolerances.

• For Hashimoto’s and similar conditions, individualized nutrition (e.g., supervised gluten trials) should be clinician-guided; avoid one-size-fits-all eliminations.

• Sleep hygiene (wind-down routine, light and caffeine timing, consistent schedule) is foundational for hormones, appetite, and mood.

• Stress regulation (breathwork, boundaries, nervous-system downshifts) is not “nice to have”—it’s therapeutic for energy and inflammation.

• Training smart beats training more: pair strength work with walking and recovery to improve insulin sensitivity without over-stressing the system.

• Change sticks when done one step at a time; sequence habits so early wins (better sleep/energy) fuel later nutrition and fitness shifts.

• Always collaborate with a qualified healthcare professional before changing meds, supplements, or treatment plans.

This is not a medical consultation—it’s an informal, supportive conversation where listeners can share their current health concerns and goals. I then explain how a functional medicine approach—focusing on gut health, hormone balance, and reducing inflammation—might help them.
