How it works.

How every listing earns its place on FastingFinder.

55 clinics 27 cities 16 countries 4.8★ avg
Step 01Quality filtering

Every clinic on FastingFinder meets an editorial quality bar before being listed. Each candidate passes through a multi-stage quality filter:

  • Minimum review volume — a clinic with too few public reviews doesn't have enough signal to be evaluated fairly.
  • Rating threshold — average rating must meet a minimum bar, calibrated per category.
  • Category match — the clinic must explicitly offer supervised fasting, not just mention it. Off-topic listings are excluded.
Step 02Editorial review

After quality filtering, each city page is reviewed for name errors, mistranslations, photo quality, and category fit.

Ranking within a city is automatic: sorted by rating, then by review volume. Featured listings appear at the top — clearly labeled.

Step 03Refresh cadence

The directory is refreshed on a rolling monthly cycle. Ratings and review counts are updated; stale entries are removed; new clinics that pass the quality bar are added.

If you spot something out of date, get in touch. Corrections are usually applied within one refresh cycle.

Step 04What we don't claim

This directory does not medically license clinics. It does not check practitioner credentials with national regulators. It does not guarantee outcomes, safety, or price. It surfaces public signals — rating, reviews, presence, photography — and explains how they are weighed.

Treat FastingFinder as a starting point, not a substitute for your own judgment. Always call the clinic before booking, and always talk to a licensed healthcare professional before beginning any supervised fasting protocol.
