Research on the ketogenic diet (KD) and aging is rapidly increasing. While many studies exist, a comprehensive bibliometric analysis was lacking, highlighting a need for more molecular-level research on age-related diseases.
Area of Science:
- Gerontology and Nutritional Science
- Bibliometrics and Scientometrics
Background:
- Growing interest in the ketogenic diet (KD) for its potential benefits on aging.
- Existing literature lacks systematic review and bibliometric analysis on KD and aging.
Purpose of the Study:
- To provide a bibliometric overview and visualization of KD and aging research.
- To identify research trends and inform future studies in this field.
Main Methods:
- Systematic literature review and bibliometric analysis of Scopus and Web of Science databases (1995-2025).
- Utilized VOSviewer software for data visualization, including keyword and cluster analysis.
- Included articles, reviews, and other publications matching specific keywords and date ranges.
Main Results:
- Significant increase in KD and aging studies observed.
- USA leads in publications, with Cunnane, S.C. as the most prolific author and Harvard Medical School as the top institution.
- Nutrients journal published the most articles; 'ketogenic diet' and 'aging' are the most frequent keywords.
Conclusions:
- Significant growth in research on ketogenic diets and aging.
- Need for more high-quality randomized controlled trials.
- Lack of molecular-level studies on KD's effects on age-related diseases.
