ok, since this is posted here every freaking time there is an article about dieting in HN, let me stress this out:

A Ketogenic diet (per the actual medical definition and not from fitness gurus) is not low carb, adequate protein and high fat. it is high fat, little to no carbs and low protein. From medical recommendations, calories from fat should be in the 85-90% range. Most of the articles you read about the benefits of ketogenic diet is the MEDICAL definition and not the fitness definition.

Also, protein as a nutrient creates a similar insulin response as carbs.

(nothing against keto diets, but they just seem to be the hip diet of the moment and annoys me when this keeps being stated)

If you look at graphs comparing them you will see protein is greatly blunted compared to carbs.

The body being in ketosis is primarily medicated by the availability of liver glycogen, temporarily insulin spikes will at worst only pause ketosis. Protein can be converted to glucose via gluconeogenesis, but (compared to felines) the human body can't do much of this and its usually only an issue if someone exceeds the standard recommendation of 0.8g of protein per lbs of lean body mass by x2 or more.

Any diet that keeps your ketones high, ie keeps you in ketosis (assuming you are healthy) is a ketogenic diet by the scientific definition.

Actually, it depends on the protein. In particular, proteins rich in the amino acid Leucine (such as whey) are actually more insulinogenic calorie for calorie than white bread.

I was referring the blood glucose, that is what matters. Insulin spikes are short term in regards to their effects on ketosis and can be useful for nutritional transport and promoting anabolism while on a ketogenic diet.
