About Fast Evidence
Fast Evidence makes short videos about intermittent fasting research. Each Short takes one peer-reviewed study, found through PubMed, and reports one finding in plain words, with the size of the study and how certain the evidence is.
How each Short is checked
Every number on screen comes from the study's abstract or full text. The authors are credited on screen, and this site lists the full citation with links to the paper. Each page also says what the study could not show.
What certainty means
Some pages show a badge such as "Source rates certainty: Low". It repeats the GRADE rating that the review itself gives its evidence; Fast Evidence does not add its own. It describes how confident the review authors are that the true effect is close to the estimate. Pages without a badge cite a source that gives no single rating.
- Certainty: High The authors are very confident the true effect is close to the estimate.
- Certainty: Moderate The authors are moderately confident: the true effect is probably close to the estimate, but could differ.
- Certainty: Low The authors have limited confidence: the true effect may be quite different from the estimate.
- Certainty: Very low The authors have very little confidence: the true effect is likely to be quite different from the estimate.
Not medical advice
These are reports of published research, not advice about your health. Talk to your doctor or a registered dietitian before changing how you eat, especially if you have diabetes, take medication, are pregnant, or have a history of disordered eating. In the UK, NHS 111 can help if you are worried now.
