our brain won’t die a few minutes without sugar, not even days. You should learn about ketones (which i’m sure you already know, why some ppl are addicted to spread misinformation?)
You would be incorrect https://en.m.wikipedia.org/wiki/Neuroglycopenia if your blood glucose levels dropped to 0, you would die pretty rapidly. It’s analogous to unmanaged Type 1 diabetes in a vague sense.
