If I remember correctly, eating a lot of eggs is the answer to fructose messing with the liver.

Yes I saw that about choline. I assume the keto people would know that (and eats lots of eggs themselves regardless), so still not sure what their gripe is.
They think the body runs better on ketones. But even when fasting for extended periods of time or on a completely carb free diet, the body maintains a certain level of blood sugar, because sugar is very important.
