whey alone, no. i suppose a cheap whey concetrate could if it was loaded down with enough crap. make sure your protein doesnt have added carbs.

dont forget the oldest diet rule in the book
yes, eating too much protein could knock you out of ketosis, espccially whey protein, but keep in mind that the body is dynamic and certain things must be happening for this to be a problem.
first, whey is highly bioavailable, so if you eat it by itself (as in no fats or fiber to slow it down), then it does cause a moderate insulin spike, but this is after it has already been turned into sugar (gulconeogenesis caused by glucagon which turned some of the protein into sugar due to the rapid absorption). the best way to minimize this effect is to mix it in with components which slow down absorption (flax or fiber) so as to minimize this.
the other variable which can cause you to leave ketosis, and the one you should really worry about, is eating too many calories. if you come within spitting distance of your BMR and you eat protein, the above mentioned effect will definitely knock you out of ketosis because your caloric intake is high enough to no longer require much ketone fracturing and instead, your body is metabolizing incoming foods. it is during this "metabolic break" that glucagon gets the upper hand and releases sugar into the system from the proteins you consume (including whey).
keep in mind though that it isn't that this isn't already happening, the thing is that once you eat enough calories to keep yourself alive with exogenous nutrients, your body gets a chance to re-stock up on its internal stores (something it's always doing) and since the body isn't needing your carbs at that moment because its busy eating your exogenous nutrients, well, glucose builds up again and no more ketosis.
(well, just for a little while, since your liver is depleted, you will go back in if you aren't too far past your BMR)
now keep in mind that im oversimplifying for the sake of illustration as the kinetics/dynamics of your ketone/glucose/atp metabolism are much more complex, but on a whole, this paints a fairly accurate picture of some of the process. remember that we are talking about a dynamic system (the body), dynamic energy sources (carbs, lipids, proteins), dynamic quantities (BMR), and physiologic deviations (how much glucose some have, how insulin/glucose/glucagon resistant or active some folks are), so some individuals will not see these effects "in their persons"
one opinion that i've developed through personal experience and through helping others is that getting knocked out of ketosis isn't the end of the world, in the long run, all that it really seems to mean is that for a few hours of the day, you didn't efficiently burn fat, that's all .... like a bump in the road, you slow down, you go past it, and move on...
I mean, i know that eating 1 gram of vitamin C will supposedly knock me out of ketosis, and i have verified this with a blood ketone meter, but as long as i keep my "eyes on the prize" (low calories), i dont stray from my weightloss goals.
the oldest diet rule in the book is the only rule that still cannot be broken (calories in < calories burned = weight loss)

i also covered a part of this discussion in another thread, and being the kind who does not like to copy-paste, i think you might enjoy reading the discussion ...
