Can a ketogenic diet help improve mood and reduce depressive symptoms? A new meta-analysis published in JAMA Psychiatry examined 50 different keto studies, totaling over 40,000 participants, that included depression and anxiety outcomes. The results of the review demonstrated a modest improvement in depression symptoms across different populations and diagnoses in both controlled and real-world scenarios, and greater symptom improvement was observed in trials that included ketone monitoring. Improvements in anxiety were also observed in most studies, but with less consistency than depressive symptoms. While many of these studies weren't originally designed to treat depression or anxiety, the consistent improvements associated with verified ketosis as well as the larger effect seen in “very low carbohydrate” diets compared to just “low carbohydrate” diets, tell us that ketogenic therapy for depression warrants further investigation. And when we combine the findings with the results of another recent additional study on keto for depression (not included in the analysis), we can’t help but wonder how many people could benefit from ketogenic therapy. In this video, Dr. Bret Scher breaks down: What the JAMA Psychiatry paper actually reviewed How ketosis may support mood and brain function Key findings from both randomized and non-randomized trials How measuring ketosis was associated with better depression improvements Safety considerations and medication interactions to watch for This JAMA review highlights growing scientific interest in ketogenic therapy for serious mental illness, driven by early scientific evidence and thousands of individuals worldwide reporting significant improvements in mental health with ketogenic therapy. Looking for more information on ketogenic…
