@Terry4 thanks for the input.
I too have no blood sugar problem with a 24 hour fast. It is my understanding that at some point in a fast your body has depleted all of its glycogen reserves.
After that balancing your basal insulin will depend on your body’s ability to produce glucose from fat. With my messed up metabolism who knows how well that signaling will work. Since Treshiba has a 48 hour activity level, and I still make some insulin, I may have a built in cushion if I skip a basal dose.
I noticed you mentioned Dr. Fung in another post. I saw somewhere that he recommends a longer fast of 5 or more days, initially for T2’s. Don’t know if I’m ready for that, but 36 hours seems doable, and might be beneficial.
