POW.
As long as your liver has glycogen and your body has hormones, it can pretty much do what it wants. It could very well have little to do with what you just ate of didn't eat.
This is the gaping hole in "eat to your meter" - not to mention the 10+ percent margin of error built into your meter. If you believe that readings are only related to what you just ate, you will have lots of false positives and false negatives. They could be related to what you ate BEFORE and/or some mixed up hormone signalling.
I can't keep consistent and good results unless I keep glycogen depleted. When it is allowed to build up, strange things happen for several days until I deplete it again.
I really only look at the total amount of glucose I'm producing from what I eat on a global basis and strive to keep it as low as possible (and that I'm getting sufficient energy between fats and carbs so my metabolism doesn't just slow down). I have to avoid fructose almost completely. This keeps me satisfied and all readings well within normal range - and keeps me med-free.
