Keto Artery-Health Claim Retracted Amid Data Flaws
A 2025 study published in JACC Advances that claimed ketogenic diets don’t promote arterial plaque buildup has been retracted after concerns about selective reporting, questionable control groups, and data anomalies; critics described the authors as social‑media influencers, and coauthor Nicholas Norwitz says they requested the retraction after a deeper analysis revealed anomalies. Retraction Watch published a detailed postmortem, while the authors have posted a reanalysis and continue keto research.
