ketogenic diet decreases migraine attack frequency
In plain terms: Does the ketogenic diet reduce how often migraines happen?
Part of: 🥗 ketogenic diet
Probably yes for frequent/chronic migraine — a controlled trial and pilot studies show fewer attacks, but the evidence base is small and short-term.

How the studies fall
What the evidence shows
Pooled evidence shows ketogenic and ketosis-inducing therapies reducing monthly migraine days and attack frequency, supported by small controlled and pilot studies in chronic and drug-resistant migraine. The base is small and mostly uncontrolled, and a randomised crossover trial of an exogenous ketone salt in episodic migraine found no benefit, so the diet is not the same as the ketone.

Disagree, or know a study we missed?
We grade by evidence, not opinions. The way to weigh in is to point us to a study we haven't cited (check the evidence table above first), or to flag a problem with one we have. Every submission is reviewed; if it holds up, the grade updates and shows in Science Changes Its Mind.
Opens a short form. You'll sign in with Google so submissions are tied to a real account — we don't display your identity, and we only accept a link we can verify (PubMed, DOI, ClinicalTrials.gov).
