I think some people are more resistant to menu fatigue than others, and I think that sometimes (not always) menu fatigue might be the body saying it needs a different mix of nutrients than what it’s getting.
There’s that guy who developed his own nutrient drink, which he claims he’s been living on for several months. (I still think I can make a better one, but every time I’ve tried to make a batch lately, someone hijacks the kitchen.)
Menu fatigue might be a learned behavior to a certain extent, too. Ever notice how kids are fine with eating the same thing for days on end? The exact item varies by kid, but when I was little it was canned chicken noodle soup.
Just some random ramblings while I wait for my sleepytime meds to kick in :)
Eventually, I hit the wall. That's it don't want any more for a long long time. Sometimes it's a weekly thing. I ate blue hake every week for 2 years. That was it. Don't want any more. I am now into clam chowder once a week.
One time I ate tacos every night for a month. My kids and grand kids seem to go through cycles too. Love pizza eat it daily, then boom oh I don't like it anymore.
I do think sometimes food cravings are related to missing nutrients.
