I get migraines if i'm not careful.
I know, in my case, there's plenty of factors that I've learned go into causing a headache.
Not eating for a long period, yes, but just being a little late on a meal "shouldn't" cause a headache so easily.
If you drink coffee or something with caffeine in it, and are for some reason missing that( caffeine addiction is a b**ch, trust me).
Not enough sleep, and stress are really common known causes of headaches.
I wouldn't think that being late on a meal would be a reason to get a headache. Maybe completely missing a meal, yes, but not being late on one.
Although, everyone is different, which makes it hard to distinguish a real cause from just the possibilities.
