Intermittent Fasting massively increasing insulin sensitivity? (T1)

So for the last few weeks I've been trying practicing intermittent fasting, though not 100% as I still have had some low sugars outside of my eating window where I have had to snack to bump up my blood sugar. But I have been noticing that my insulin sensitivity is practically double what it used to be (hence all the low sugars).

Anyone else have any experience with this?
