I once fell into a blog chain of newly diagnosed T2D diabetics, and it was horribly depressing to read how earnestly they struggled with the medical advice they were given. They dutifully ate exact numbers of carbs with each meal and the mandated snacks in between, then tried to "balance" with insulin.

All of them had their blood sugar blow up on them, got labeled "brittle diabetics" and were tormented by cravings and watching larger portions, because their blood sugar levels were all over the place.

One functional medicine book explained it as the trap that is Standard of Care. It mandates a minimum level of carbs to cover the insulin that is prescribed!

High blood sugars cause "inevitable complications" down the road, so nobody can get sued over that. While low blood sugars can kill, and that's something a doctor can be held liable over.
