I've been on sloppy paleo for a while, but I only started doing intermittent fasting more recently at a buddy's repeated urgings. I have fairly vivid memories of getting headaches sometimes after missing a meal or two in succession. After being on a paleo-ish diet for a while, I only then narrowed my feeding window to between noon and 8 PM over a couple of weeks. I've since gotten to the point where I can eat one meal a day most days if I want, but hunger headaches are a thing. (I'd still expect to get them if I were to do a multiday fast.)
