I've not had problem with dairy or eggs, I was raised on a dairy farm in CT that sold both milk and eggs. Some people can't handle these products, and as you write, keto can still be doable. But there are also many women (and men) in the keto groups where I still hang out who "stall" above goal, eating what may be too many allowed high-fat foods. "Keto"... however that is defined, just doesn't work for them. And they are complaining about it, and moving on.
