I've always been a bit confused on how things work to be honest. At one point a few years ago I had a summer of being really careful, or what I thought was really careful, eating salads and the like and was pretty confident at my HBA1c test and was mortified when it went up to 64. So annoyed I was that I fell of the wagon completely and ate a lot of what's perceived as junk food for the next three months and was in a pretty dark place mentally. Next HBA1c three months later and it had dropped to 46! I was baffled and so was my GP! I'm certainly not advocating junk food by the way. Maybe I was eating more meat and not loading salads with sugary dressings or maybe a more hearty chicken/shish kebab (more meat) was filling me up so I didn't pick and snack?! I'm still confused!!
