I swear I am the only person who’s migraines have gotten worse going keto and fasting. I used to only get them once a year. Now its every few months. I have been keto for 4 years now and they have gotten progressively more frequent in that time. I’ve tried all kinds of electrolyte formulas, fasted all kinds of lengths, and tried cutting out food (to the point where I am essentially carnivore right now) to no avail. Just had one last week and it was painful despite the copious amounts of salt under the tongue! Other wise I feel great with lots of energy, great sleep, balanced hormones and I lost all my weight…but the migraines. Nope - no help there.
I’ve come to the conclusion its partly based on hormonal fluctuations, viral infections (I haven’t gotten sick in like a year but when my kids are fighting colds and I start fighting it off, it seems to trigger them) and the extreme weather changes. Each one individually doesn’t trigger it, but a random combination of two or three of them does. Therefore, they are hard to predict and prevent them. I have yet to find any solution.
Sometimes I wonder if exogenous ketones would be helpful?
