Just throwing this out there, I am not sure of this myself. But aren't there studies where you could do without insulin shots if you avoided carbohydrates while feeding on protein and fat?
"The LC diet, which was high in unsaturated fat and low in saturated fat, achieved greater improvements in the lipid profile, blood glucose stability, and reductions in diabetes medication requirements, suggesting an effective strategy for the optimization of T2D management."
I haven't heard of any formal studies where they got off of medication 100%; I've only heard of n=1 studies (single person reporting) where that has happened. The most remarkable n=1 is this from a type 1 diabetic: https://www.reddit.com/r/keto/comments/2rnn9b/doctors_can_su... but in this case the person is still on it which isn't a surprise as they are type 1.
In short, not only are the self-reported anecdotes of a person with a bachelors in nutrition not adequate evidence of anything, but even formal studies are suspect. As far as my own opinions go I suspect that I would be inclined to believe what she says, but truths that mesh with one's preconceptions demand an even higher standard of evidence. Were I you, I would not be promoting this person's work, and I feel it was inappropriate as a response to the parent.
The brain can only run on glucose. Because of that, the liver produces glucose from 'whatever', including pure protein. Leftover glucose ends up in the body, which can only be dealt with insulin.
Now, things like alcohol attack the glucose emitted by the liver, as it must handle alcohol before anything else.
But no, at least for type 1s and t2's with severely degraded pancreatic function.
For me, I'm recent T2 but handling it well with protein and fats to great effect (-40 lbs, normal blood sugar) since December 7. I'm sticking to roughly 'atkins style diet' to a great effect, called "Eating to the Meter".
