Did you get any further and find something else to feel weirdly personally attacked by? Not all of this has to apply to you and while I think the whole thing is a bit overwrought and silly this is a pretty visceral reaction to a relatively innocuous question.

Personally I actually can use a reminder to eat because I have little appetite and won’t realize I haven’t eaten anything until the headache kicks in, which is a potential migraine trigger for me as well. To be clear I don’t want/need to eat something every four hours but that doesn’t make the question less valid for the purposes of reminding me to consider when I last ate.
