Abstract

The commentary on the paper entitled "The effects of ketogenic diet on systolic and diastolic blood pressure: A Systematic Review and Meta‐Regression Analysis of Randomized Controlled Trials," provides a critical appraisal of the evidence presented and identifies key areas for further inquiry. The original paper, which compiles results from 34 high-quality studies, concludes that ketogenic diets significantly reduce systolic and diastolic blood pressures. While acknowledging these findings, the commentary highlights several issues, such as the lack of uniformity in intervention durations and the observed heterogeneity in systolic blood pressure results, suggesting that the impact of the ketogenic diet may vary significantly based on these factors. It also points out the need for clarity in discussing the term "ketogenic diets" due to the diverse protocols that exist. Moreover, the commentary enriches the discussion by proposing that future research should explore the underlying physiological mechanisms in greater depth and consider the impact of dietary composition on metabolic health and blood pressure regulation. This reflection aims to refine the conclusions drawn from the meta-analysis and suggests a more nuanced approach to studying and implementing ketogenic diets in hypertension management.
