About

Fasting Index is an independent reference for fasting questions. It exists because the answers currently available are mostly published by companies selling the thing being asked about.

How it is funded

Through its own guides and tools. It does not sell supplements, and takes no affiliate revenue from any product it assesses. That constraint is enforced in the codebase, not just stated here: a build that tries to add a supplement to the catalogue fails.

Editorial review

No clinician reviews this site. It is written and source-checked by Tristan Grech, who is not a doctor or a dietitian. Every mechanism claim is traced to a primary source, and that source is shown on the page with its journal, year and PubMed ID so you can check it rather than take our word for it. The citations are re-checked against PubMed by a committed script, which fails if a record stops resolving or its details drift. All of them passed on 15 August 2026. The script is run before publishing, not on every deploy.

That is a real safeguard and it is not the same safeguard as clinical review. It catches invented evidence; it does not catch a reasonable-looking inference a clinician would know is wrong. The editorial and review policy says so at greater length, and the reviewer slot is built and waiting for the day there is budget for it.

Corrections

If something here is wrong, we want to know and will say so on the page when we change it, though this domain currently has no working inbox, so there is not yet a good way for you to tell us. Where evidence is genuinely mixed, the entry says that rather than picking a side for the sake of a cleaner answer.
