T1D here who has a CGM, this is not true for me at all. Without _enough_ insulin on board spaghetti would start spiking my blood sugar ~20 minutes after consumption and the sky is the limit. With something like steak I could basically skip injecting insulin beforehand, but would need to inject later to deal with the delayed rise. The rise from protein in general is never anywhere near as drastic as from carbs, even the "healthy" carbs.

This can be measured scientifically:

Note that insulin level and blood sugar level are two independent things.

Sorry are you agreeing or disagreeing with me?

That Wikipedia article doesn't seem to cite very many studies. At least from my own perspective I can tell you that even after two hours of eating many kinds of meals your blood sugar can rise and you will need insulin to counteract that, either produced by the body itself or injected.

As an aside I would really like to know where the two hour postbrandial measuring for blood glucose levels etc. comes from as it feels completely arbitrary.
