And keto does call for a moderate protein intake as well, as excess proteins are ultimately converted into glucose.
It seems there may be a bit of a straw man being built up here, based on the fact that it is very easy to tend toward an excessive meat/dairy based diet on keto, but nothing about it requires doing so.
Personally I know my reason for overdoing meats and dairy is that while I do a mostly keto-leaning diet, I'm also lifting weights, and have a higher than normal protein target for muscle growth. While vegan bodybuilders are a thing, looking at their food intake will let you know how difficult getting 150+g of protein a day from plant sources is -- there's a reason cows eat ALL day long.
Meat is the original processed protein source -- the machinery is just biological. Many of the same drawbacks as other processed foods, and many of the same conveniences.
I see you haven't run into the anti-seed oil nutjobs.
Generally in calculating their carb/sugar intake people will reduce carbs/sugars by fiber, it’s not exactly scientific but probably works for the most part. I don’t even bother calculating carbs for stuff like spinach, kale, or Broccoli.
Carrots have a high glycemic index, but a low glycemic load. That is, you will rapidly absorb the glucose in them, but the amount of glucose they contain in the first place is low.
Anecdotally, I've never heard anybody complaining about insulin spikes in their continuous glucose monitor from eating carrots.
I never used a blood glucose monitor, but I did use ketone test strips and small amounts of shredded carrots added to a spinach salad would have pretty significant impact on my detectable ketone levels.
I was often surprised by things that knocked me out of ketosis. For example normal serving sizes of whey or casein protein powders (<1g of carbs/no sugar)could.
I’m not hating on carrots or demonizing them, just for my purposes I avoid them and other foods that knocked me out of ketosis or consistently had significant impacts on my detectable ketone levels.
