It’s surely harder in the beginning. I came from low-carb (80g net was enough for everything from day 1, I hadn’t sacrifice anything at all, just got benefits!) and used 40g net carbs on keto so one might think it was easy. It wasn’t too hard for a while as I would quit earlier then but it was still very different from low-carb. I still could eat anything I wanted as keto doesn’t ban anything (at least I don’t believe in such things, keto is all about ketosis to me… well certain items are trickier on keto but I doubt I ever found anything except melons and cauliflower practically impossible to eat on this woe. I am good at ridiculously tiny amounts. except cauliflower, I couldn’t go below 1kg with that if I just fried them) but I horribly missed my veggies (only could spend 25g net carbs on them and I hate green leaves so I didn’t eat them).
But one learns… And even changes. It gets easier for the vast majority. Some people never will feel fine on keto, it least but it’s extremely rare (probably most of them can’t even bring themselves to try it, maybe they don’t feel the need as they are thriving on high-carb or low-carb or whatever non-keto they do).
I found keto the cheapest woe I ever had (despite not eating any less) but carnivore is probably even better as long as I stay away from ruminants and seafood as that is very expensive and not so available here. There are other options and I prefer pork anyway, fortunately I handle it well, not everyone is like that.
There are very different keto styles anyway. My original, too carby vegetarian keto is nothing like my carnivore-ish
Interestingly, getting out vegetables immediately alleviated some boredom (I always use a big variety but I still have times when I find my food not enough exciting for a while). One would think it’s the other way around but not because eating very low-carb makes my variety/excitement need significantly lower. It’s like eating carby treats and desserts in huge variety often don’t make me any happier with my food, it easily makes me less satisfied in the end. Stupid carbs, I often say
I become a different person with extremely little carbs. Easier to satisfy. I can’t go to low with variety but I don’t need whatever people do with their dishes, sauces, marinades, very mixed vegetable side dish… Not needed, just nutritious, tasty food. Sometimes I don’t even want it to be so tasty, I just want to get satiated. I came a long way… I am still addicted to food but less.
But if someone wants, they can add so so so many things to their keto food. I hardly can imagine it being boring. Missing some carby food here and there, I still can remember that. But boring keto food… Unless I stubbornly do carnivore and run out of all meat (it happened once, never again. I love my eggs and eat them in huge variety but that’s still not enough even for a single day).
It helps a lot to like most of your keto staples and not craving the non-keto ones but sometimes you just need recipes, tricks, some nice sauces and spices…?
