I disagree with the author however on the following point:
"injecting insulin ~15min before you start eating would do wonders for neutralizing the BG spike, the issue is, nobody does it, because what if you then get a smaller serving at the restaurant or it gets delayed?"
My doc told me the same, which I think is insane. "Here is a hack that solves 80% of your problems but nobody does it, so don't bother." WTF?
If you get a smaller serving, order some bread or eat some of your emergency snacks you should always have. If it gets delayed, do the same. You don't need to cover the whole insulin dose, just delay the hypo a little bit.
Relax. We live in an industrial world where glucose bombs are available always and everywhere. You'll be fine.
Injecting 15mins beforehand has made my life so much easier that I would not miss it for anything.
Feel free to ask me anything.
