OK, now this is weird. It's now 4 hrs since my muesli & my BG is now 4.0!
😱 Never had a reading that low. I'm confused!
Do you routinely keep a food diary, including carb count?
Sometimes when we "surprise" our bodies by having something we don't usually have; which for us would probably be something containing more carb than usual, we experience an extraordinary high. A second or third trial of the same food can often show the body coping better. That phenomenomenomenomenon is sometimes referred to as the "last meal effect".
Some folks find, like you, that if, again, eat something carbier, then test longer than the 2 hour point, they overshoot their starting figure. Some just a bit and some by a lot. On a one-off, those can sometimes be "justified" by meter variances, bringing the "real" numbers closer together, and sometimes it's actually so. It could be that with improved insulin resistance your pancreas panicked a bit and generated more insulin than it required. this time around. I don't know if such a named phenomenomenomenomenon officially exists. If it does, I haven't found a name.
Personally, I wouldn't draw any conclusions by your "today" experience. I would want to see if it is a repeatable phenomenomenomenomenon or one of those weird things that happen for no apparent reason.
It could be an idea to try to replicate today as closely as you can, by repeating your activity levels and repeat the food you have eaten all day, as cumulative effects can have an impact.
You're our very own lab rat.
