Free, plain-language education about intermittent fasting
FreeFasting.com is an independent, free educational website about intermittent fasting. It explains how the common fasting schedules work (16:8, 18:6, OMAD, 5:2, alternate-day and longer fasts), what the research does and does not show, and the practical and safety considerations that come with each approach.
The site does not sell programs, supplements, coaching, or apps. Everything here is free to read, and the fasting timer on the homepage runs entirely in your browser.
Our aim is to help readers understand fasting well enough to make an informed decision together with their healthcare provider — not to persuade anyone to fast.
Articles describe general information. They are not medical advice and cannot account for your health history, medications, or circumstances.
We avoid claims about guaranteed results. Responses to fasting vary widely, and many findings come from short or small studies.
Where research is limited, mixed, or mostly based on animal studies, we say so, and we try to separate established findings from speculation.
Pages explain who should not fast and which warning signs mean a fast should stop, alongside the practical how-to.
We write for general readers: clear explanations, practical examples, and no jargon without a definition.
Pages show when they were last updated. If you spot an error or outdated information, please let us know.
