Just to expand on this and clarify one point, as someone who's been keto for over 12 years, the meat part isn't even necessary. Nowadays I pretty much get all my protein from mycelium (Meati cutlets and Quorn grounds), eggs, and whey protein isolate, with plenty of healthy* saturated fats from butter, coconut milk, and heavy cream. Not that I'm a strict vegetarian, but I generally don't buy meat to cook at home anymore and no longer consider it important for a well-formulated keto diet.

I point this out because I've gotten the impression that many seem to view keto and veganism as opposite sides of a "culture war", and use that to justify reacting to one or the other with hostility. In reality, they're entirely orthogonal. One is a range of macros while the other is an ethical philosophy, and they aren't in any way mutually exclusive.

*: To preempt the usual comments on this, my current LDL is 54 and HDL is 57. At its lowest point a few years ago, my total cholesterol was exactly 100. I don't buy that saturated fat is necessarily unhealthy at all.
