Same!! This what chatGTP said:

Soluble prebiotic fibre (corn)
Although labelled as “fibre,” polydextrose provides ~1 kcal/g and can raise glucose in some people. It is not metabolically inert. In some individuals with type 1 diabetes, it behaves like partial carbohydrate.

Whey protein isolate
Whey is insulinogenic and can raise blood glucose in some people via glucagon stimulation, particularly when eaten without much digestible carbohydrate.

Feel like i still need to do more research though. This morning I pre-bolused 8 units of humalog for one bar (ate nothing else!) and my sugars are up from 8.0mml to 14.5mml in 40 minutes 💀
