I could easily go 24 hours without eating, just due to not thinking about it. In fact I just noticed on writing this OP that I haven’t actually eaten anything in the last 24 hours although I am now hungry and planning to cook something.
Yet I know all these people who get fussed about missing a meal. Am I abnormal? If it’s relevant, I’m also very fat (this comes from alcohol rather than eating though, I think)
