I'm American, and I have to disagree. I have the same thing for breakfast every day, and I love it. I usually have the same thing for lunch, too. It's convenient and I change it up just a little now and then. For dinner, my daughter and I do different things. I think that embracing this is a good thing. It's comfortable. It's safe, and I am content. On the weekends I do change it up too, but during the week, I find my favorite foods to be part of my daily routine. I like it.

I tried eating a particular dish every day for a while. (To the exclusion of other foods.) I didn't get tired of it -- I loved it and still do. But I had to stop because, after a while of this, I would still be hungry after eating a large meal. My stomach would be physically full, but I'd be hungry anyway.

I'm still not sure what the problem was. It was a dish basically consisting of lentils, onions, and shredded chicken, spiced heavily; I'd eat it spread over bread.

Try milk, cheese, grains, egg, muesli, stew, varied foods, get recepees known to work like ayurvedic ones or good veg recipes. Avoid too much bread, good rice (basmati) can be filling. Organic ecological foods also.

If you only eat one dish, it better have everything needed and even then it can be lacking. No need to torment oneself.

Your body was probably carving some nutrient not found in your dish

Yes, I agree, but I'd like to know what it was. Best guess so far is fat.

"If there are enough rabbits, the people eat till their stomachs are distended; but no matter how much they eat they feel unsatisfied."

Easy enough to add a little fat into that meal with a bit of full-fat yogurt! Although there's already some fat from the chicken, no?

I admit, that sounds like a great meal to me!

Or some mineral or vitamin?

I could eat the same thing every day, as in I don’t really care what I eat.

However it doesnt feel like a good idea for nutrition reasons. So I try to eat as different as possible with minimal effort instead. Like getting the dishes I’ve never heard of when eating out.

Yeah I grew up in Southeast Asia and it’s no different.
