As stated above. I can go months without eating an egg, for example, and suddenly crave eggs benedict for breakfast everyday.
Good thing is my dietitian is aware of this executive dysfunction/quirk/habit and works closely with me to help me out planning meals in a way that works me.
Right now I am on a soup kick: Soup, soup, soup everyday, all day.
ETA A word
I agree with you that craving something is not a dysfunction. I was makig a reference to my own executive dysfunction and how it interferes with meals/feeding but I think I didn’t do it properly. Language barrier and what not.
By “executive dysfunction”, do you mean sometimes craving eggs?
Are you getting enough vitamin D?
Could be neurodivergent. I’ve ADHD and it’s an executive dysfunction disorder and I go through periods where I get really into a specific thing for days, I’ve definitely experienced hyperfixation on things like milkshakes or waffles, my current food fixation is cheesy chips because I’ve been unwell and haven’t had any for a long while.
