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
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.
