I wanna start 24 hour fasting, how can I adjust my body? Once I'm around 16 ish hours without eating, I start to really feel it. Might just be placebo, but if I force myself a bit further, kinda feels like my energy starts coming back a bit? Anyways yeah, how to do this safely?

I do deal with reactive hypoglycemia. If I eat a moderate amount of carbs with no fat or protein, I crash badly a couple hours later. If I eat low or high carbs with nothing else, I'm usually okay. Or if I eat any carbs with some good protein and fat I'm also okay

But considering I can go 16 hours without eating anything without issues, I can safely assume my pancreas is functioning normally and I can safely push further
