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 don’t find it worthwhile to spend mental energy thinking about food, so I eat the same things constantly (though I occasionally change the menu). My wife doesn’t like eating the same thing more than a couple of times in a row, so she always wants to make something different, but is constantly stressing about what to plan for meals. She reinforces my view that food planning is not worth mental energy.
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!
