As I had Type 2 diabetes for a short time after a flu and because I studied veterinary medicine, I can assume to have a bit more data than you.
The assumption that there is no glucose used by your body when you are eliminating it from your diet is flatly wrong.
Firstly eliminating glucose and anything we can make glucose from (carbohydrates and protein) from a sustainable diet (= not using up your reserves) is next to impossible.
Secondly even when there is no protein and no carbohydrates in the diet, your body will claim the protein from your muscles and turn that into blood sugar.
Thirdly, some tissues in the body, especially the brain, just plainly need glucose. The body will make glucose, no matter what, even at the expense of destroying itself.
There is a lot of hype, marketing and simplification around ketogenic diets. Not all of that translates down to the actual physiology. Ketogenic diets are beneficial to diabetics, fasting will lower insulin tolerance, whether you are a diabetic or not. This is well known, and research is going on. There are even indications that fasting leads to more insulin production in Type-1 diabetic.
Can you reference any sources to confirm the body keeps producing glucose from protein once it has switched to ketososis (which you don't have to eliminate protein for, the diet just is to be lots of fats and some proteins) the brain always needs glucose and ketone bodies can't replace it completely? I don't mean you are wrong, you just are the first person I've met who tells there is glucose in ketosis (don't confuse it with diabetic ketoacidosis) and I'm curious to know for sure.
Note how both articles don't talk about fasting or ketogenic diets. Basic idea: even a low blood sugar level (let alone 0) is very very bad news. The metabolism will do its utmost to make glucose, even from amino acids. That's why even people who eat nothing don't have hypoglycemia all the time...
