Keep in mind I am a newbie still… But I doubt boredom will be a serious issue in the future. We will see. My experiences this far are interesting and promising.
Honestly? I don’t know. I cut out plants - and I suddenly lost my existing boredom with my food. I was truly surprised. Less variety made my food more exciting I guess carbs interfered with lots of things.
It’s surely individual, maybe subject to change, obviously food choices matter a lot too.
I eat some cheese though but very little meat at the moment so my food has way less variety than yours, probably. And it’s perfect for now. If I have enough meat, cheese loses pretty much of its importance.
I am a hedonist and I need variety. Much less in extremely low-carb but I do. And I have it.
I have little experience with meat but eggs are my most important staple food and I have plenty of good recipes (carnivore would be way harder without my low-carb times rich in eggs). Now I added meat and I got my flatbread, it filled some void. If I use some different meat, it gets different, I don’t even need spices, just salt and quite tasteless meat works too, eggs are tasty enough, meat adds a hint of flavor (it’s more recognizable than alone) and texture.
If I ever get bored for some reason, I just need to buy some different meat. There is a huge variety, it’s hard for me though as I only buy meat from a good farm - but I can buy fish from a shop as caught fish is available even in the nearby small villages. I could buy some salmon if I really wanted/needed and that’s nothing like the super lean white fish I ate today but with my cooking methods even that was nice just not awesome, I can live with that.
I could eat veal or tender lamb, duck or rabbit, goat or seafood, roosters and hens and tender, very young chicken, even wild animals (I prefer deer despite my fav meat is pork. wild boar is just too lean and boring to me. deer is somehow special), various organs, I can cook and fry and bake and add spices and condiments (including onions and garlic, those are super tasty so a little goes a long way. I need such things for not very tasty meat only, most dishes of mine has no spices, just salt. I love to add something to my omelets. Meat or cheese or mustard but if I fry it in lard, that’s often enough and nothing is wrong with a boiled egg, it is good even without salt, all alone)…
I admit I would quit the “only beef and water” style the second day (if I was very determined to last that long). But a bit more relaxed one is enjoyable and I was never bored this far (one week? but I had that when I ate a near carnivore meal vs a normal keto one) despite my meat variety was limited, just smoked pork (I love it so much even a little makes a huge difference), chicken, beef and lean fish, not even any organs yet and I use super simple recipes.
Probably some people get bored of it after a while… Especially with stricter rules unless they love beef as I love eggs and pork and needs way less variety I do.
Of course, some people consider eating just fuel. I almost never accept below 9-10/10 meals. Normal people are between these two extremes but we can change. If it would be about my health, I would sacrifice very much. If my hedonism, convenience and other important things clash with health and well-being quite seriously (I mean, it’s not just some article about what is bad or something, I KNOW and maybe feel it significantly harms me), health is the winner, no matter what. I am just lucky I enjoy the food that is good for me pretty much. At least some of them. But if beef would be my only way, I would learn to like that, I already found some nice dishes after my first less than stellar ones. So I do what is good for me and my mind will ensure I will enjoy the hell out of it, usually. But if I have choices (I always had), I choose the easier, tastier, less boring way.
I eat for fuel sometimes, I guess everyone do. It’s just super rare and I still need tasty food for that even if I don’t enjoy it, just realize it’s good. I can’t eat bad tasting or tasteless meals. Well, unless I am starving since weeks or something. But it’s very, very individual.
