RETRACTED ARTICLE: Ketogenic Diets Are Associated with an Elevated Risk for All Cancers: Insights from a Cross-Sectional Analysis of the NHANES 2001–2018
Abstract
We, the Editors and Publisher of Nutrition & Cancer, have retracted the following article: Liu, Y., Qu, X., Liu, D., & Yang, D. (2025). Ketogenic Diets Are Associated with an Elevated Risk for All Cancers: Insights from a Cross-Sectional Analysis of the NHANES 2001–2018. Nutrition and Cancer, 77(9), 996–1006. https://doi.org/10.1080/01635581.2025.2497095 After publication, concerns about the study methodology were raised by multiple third parties. The Publisher contacted the authors for an explanation to these concerns but did not receive a response. Following further investigation, it was determined that the study methodology does not support the article’s reported results and the conclusions of the article are considered misleading. As verifying the validity of published work is core to the integrity of the scholarly record, we are therefore retracting the article. The authors listed in this publication has been informed. We have been informed in our decision-making by our editorial policies and the COPE guidelines. The retracted article will remain online to maintain the scholarly record, but it will be digitally watermarked on each page as “Retracted”.
How strong is the evidence?
Evidence Hub reads this as a cross-sectional. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause.
