Story time.
2019 had yearly blood work done all normal. Decided to do IF to drop some weight. Been doing 16:8 since 2020ish. For 2 years now I’ve normal a1C of 5.1 & 5.4 but elevated morning fasting numbers 105-111.
Recently stopped doing IF and now my morning numbers have normalized.
Any science behind this?
Has this happened to anyone else?
Very simply put: you trained your body to use its own stores instead of expecting food during your fasting time.
When you stopped IF, your insulin & counterregulatory hormone responses re-aligned, and your body no longer anticipates that need to pull glucose from internal stores and release into the bloodstream in order to function.
(This is all of course assuming you have no medical conditions, take any medications or supplements, etc that could potentially negate or modify the bodily processes I mentioned above).
