Good day CT!
We have couple of type-1 diabetics talking about stuff like insulin sensitivity and effects of exercise etc.

We have slightly discussed this phenomenon you mention here. I must say what you say seems to be true in my case at least. Do you happen to know more about the subject or could you possibly point to a source of information conserning this?
I’ve read some insulin/peri-workout nutrition recommendations for high level bodybuilders and it took me a while to figure out why the insulin numbers seemed so high compared to the carb content. But then I realized that I’m doing more strength focused training and therefore requiring less insulin during workout, thus validating your point.
