Other Common Program Questions
How do health coaching certifications compare in terms of curriculum?
A useful curriculum comparison lens:
Foundational coaching skills (must-have)
- Motivational interviewing, behavior change, ethics, scope-of-practice, practice coaching
Health literacy & wellness foundations
- Nutrition basics, stress/sleep, movement, habit formation
Specialization
- Functional medicine orientation (FMCA), holistic wellness (IIN/MBG), functional labs (FDN)
Board-eligible pathway
- Look for NBHWC program approval and standards alignment. NBHWC+1
How does the Global Healing Institute compare?
Global Healing Institute (GHI) positions itself as a Natural Health Coach program with a curriculum that includes topics like detox strategies and similar natural health themes, with advertised pricing and a self-paced approach.
Key differences
- FMCA: IFM collaboration + NBHWC approval (strong professional alignment).
- GHI: program appears oriented toward “natural health” and offers its own certification; pricing is explicitly listed (often with discounting).
If your goal is board-eligible, healthcare-adjacent coaching: FMCA is the cleaner comparison category.
How does Functional Diagnostic Nutrition (FDN) compare?
FDN is not the same category as general health coaching programs. It’s positioned around functional labs / practitioner training and is typically priced at a premium.
FDN (Functional Diagnostic Nutrition)
- Emphasis: functional labs + root-cause protocols (practitioner-style track)
- Cost signals: published pricing shows five-figure tuition for certification.
Rule of thumb:
- If you want to be a health coach working within scope, compare FMCA / MBG / IIN.
- If you want functional-lab practitioner training, compare FDN to other lab-focused programs, not standard health coaching certifications.
