I was very used to tons of fat but when I tried out carnivore, I was nauseous just because fat was a big part of my food, I didn’t have the usual vegetables and other things with their significant volume to “soak up” the (less than usual amount of) fat. My fat percentage dropped a bit as I couldn’t stand a higher one back then. So it’s not only the fat in grams, it matters what we eat it with, not surprising.
Only egg and bacon, that’s fatty!
I changed quickly, only some days were like this (but I never used a very big fat percentage anyway, just trying it out later when I felt ready).
But I still would have problem with 2 eggs with 6 slices of bacon. Salt-cured fatty meat? I need lots of eggs with it, it’s super satiating and super easily turns me off if I don’t have a lot of other, more neutral stuff with it. Of course, other people have other experiences…
If it’s just the amount of fat, I have no problem, I always ate very high-fat and easily overate fat on any woe except carnivore(-ish) if I choose very fatty, not particularly satiating but tempting, tasty food items. Bacon and eggs as a combo is super far from that and if the bacon is too much (compared to the egg, I mean but if I get too full, that works too), it turns me off, make me nauseous and triggers my sodium aversion for a while…
We don’t need to eat super fatty on keto if we don’t even have some huge energy need, fortunately. As long as we can handle the protein, some people can’t avoid a big fat percentage even with a smaller need.
