Calorie restriction and fasting

From 2021 to 2025, 120 animal research papers mentioned calorie restriction and fasting and at least one behavioral test.

That is 1.8 times the 68 papers of 2011 to 2015. Between the same two periods, all the animal research papers that mention any of the 90 tests we count grew more slowly, to 1.2 times as many.

The tests mentioned with calorie restriction and fasting

Each bar is one test, with how many of the 120 papers from 2021 to 2025 mention it, and what share that is. A paper that mentions two tests counts under both.

Disease models in papers that mention calorie restriction and fasting

Each bar is one disease model, with how many of the 120 papers from 2021 to 2025 are tagged with it, and what share that is. The model comes from the paper's MeSH terms, the subject headings the National Library of Medicine adds when it indexes a paper. A paper without MeSH terms gets its model from PubTator 3, NCBI's text-mining service, if PubTator 3 finds the disease in the title or abstract. A paper can count under more than one model.

Which species the papers used

Each bar is a share of the 120 papers from 2021 to 2025. A paper can use more than one species, so the shares can add to more than 100%.

“Other animals” counts papers that use none of the species this chart names.

NIH funding

18 of the 120 papers (15%) had NIH funding. NIA, the National Institute on Aging, funded the most, 8 of them. A paper counts as NIH-funded when its PubMed record lists an NIH grant, or when NIH RePORTER links it to an NIH project.

How we counted

A paper counts here when it is animal research and its title or abstract mentions calorie restriction and fasting and at least one of the 90 behavioral tests. A count is a number of papers, not of experiments, labs or animals. A paper that mentions calorie restriction and fasting only in its methods is missed, so the count runs low.

A paper is animal research when its MeSH terms name an animal species. If they name none, NCBI's text-mining service PubTator 3 has to find one in the title or abstract. Papers on animals other than mice, rats, zebrafish, flies and primates count only when they also mention a test. Many of them study people or use the same words for something else.

The search terms for calorie restriction and fasting are in the download Animal models and brain techniques. The counts in the chart of tests are in Tests mentioned with each model or technique. The full method, with each source and its terms of use, is on our main page, Behavioral tests in published research.

More animal models

Each animal model with 100 or more papers from 2021 to 2025 that mention a test has a page. These are the others, each with that count.
