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 sympathise! Meal planning, buying ingredients, realising you messed up and now half your vegetables have rotten, etc is a nightmare. I do envy people who can just get into a routine and eat the same stuff. But I defintely crave variety, and I feel like what I eat each day is probably two thirds of the joy I experience. I’d defintely go without hobbies, activities or possessions to eat slightly nicer food. Eating a nice meal with people you love feels like the pinacle of life experiences for me, and luckily it’s one you can do multiple times a day!
Learn to improvise. Make something with what you have in the fridge so it doesn’t rot. You don’t need to plan every meal exactly.
