Evidence summaries on fasting and metabolic health

fasting.com

Cited guides to intermittent fasting, water-only fasting, and the fasting-mimicking diet.

fasting.com covers three areas of fasting research: intermittent fasting, water-only fasting, and the fasting-mimicking diet. Each page is a plain-language summary built from primary research, cited by name, with a visible publish date and review date.

How pages are written

Every page on this site is written and kept current by the fasting.com team. "Last reviewed" means an editorial review by that team against the cited research, checking that each page's claims still match what the underlying studies report. It is not a medical review, and no page on this site is a substitute for talking to a clinician about your own health.

The citation standard here is completeness, not convenience. A page aims to reference every study that applies to a claim it makes, whether that study supports the claim, found no effect, contradicts it, or offers only limited evidence, and names the authors directly in the text rather than citing research anonymously. Where the published research disagrees on a question, the page says so, in a section headed "Where the studies disagree," instead of quoting only the findings that are easiest to agree with.

Medical caution

This is general information about fasting, not medical advice. Fasting can affect blood sugar, blood pressure, medication timing, and nutritional status. Talk to a clinician before starting or changing a fasting practice if you are pregnant, under 18, living with diabetes or another chronic condition, taking prescription medication, or have a history of an eating disorder.
