Ketogenic Diet and Endocrine and Metabolic Diseases: A Bibliometric Study and Visualization Analysis.

BACKGROUND

The ketogenic diet, known for its high-fat, low-carbohydrate composition, has been extensively studied in endocrine and metabolic diseases. This study carried out bibliometric analysis to examine the research trends in this field over the past 20 years, aiming to provide insights for future studies.

METHODS

We searched the Web of Science Core Collection for all relevant papers. VOSviewer was used for network visualization, the bibliometrix package of R software (version 4.3.0) was utilized for data analysis, and CiteSpace was employed for mapping and trend analysis.

RESULTS

This study encompassed 508 relevant articles spanning from 2003 to 2023, authored by 2827 researchers from 887 institutions across 57 countries/regions. The total number of publications increased from 3 in 2003 to 508 in 2023, showing a steady growth trend. The United States emerged as the predominant contributor in this field, followed by Italy and China. Notably, SAJOUX I consistently exhibited high activity in this field, according to the analysis, with an h-index of 13. The journal Nutrients has consistently made substantial contributions to this field, accounting for 19% of all publications. The keywords "obesity," "ketogenic diet," and "weight loss" appeared most frequently, with "obesity" occurring 163 times.

CONCLUSION

This study used a bibliometric method to analyze the impact of the ketogenic diet on the endocrine metabolic system. The research identifies recent frontiers and trending directions, providing valuable references for scholars in this field.
