OP should read the 'thin fit' thread, but essentially, I am in a similar boat, HBA1C 43. I am VERY interested to know more about the exercise/adrenaline response. I got a couple of freestyle libre sensors and wore them over the whole of December, including a trip to see the family in Mallorca and Denia (great for cycling). The biggest spikes in that time were seen not from eating but from exercise. I mean some fairly hard exercise, so 30-45 mins at threshold heart rate climbing in the mountains would spike glucose to 13, whereas eating a large bowl of cereal was <10. I do wonder whether my prediabetic results are down to this; in this case (in one respect at least) is exercise unhealthy? Or is that high sugar 'OK' because it's exercise? HBA1C might not tell the whole story in this case.
Doing this exercise however creates a great halo effect for the next day, if you do that every day it really controls spikes from food.
Well to try and answer two questions
The idea of 'Spiking' as I understand it, IS something diabetic AND non diabetic people do
THAT is normal.
The issue seems to be the longevity of the spike

I liken the body to a pot.
A fuel tank, if you like
Over time for those who build up resistance to carbs (type 2). The pot doesn't drain out as well at the bottom like it does for non diabetics .
At some point it begins to spill over as it's overfill drips then pours into our bodies.
Our poor body tries it best to mop it away and tidy up, by stashing it into places it shouldn't really be
(Mainly as fats wrapped around every organ and as the visceral fat around our bellies in particular )
And there is an argument that diabetes MAKES people fat.
V
FAT turns people diabetic .
At some point that stuffing away of fats causes issues and if left untreated begins the progressive nature of the illness of type 2
The solution for type 2's is
Follow doctors advise and slow but don't stop the decline
Follow a low carb diet and POSSIBLY slow the decline enough not to as big an issue as it could be .
I imagine well managed the decline might not even be an issue as other age related illnesses get us .
So exercise spiking ..normal.
Spiking after food ...normal.
But for type 2's it's the duration of the spikes that causes us damage .
Issue for type 2 is HOW to reduce the pot of glucose inside us
And how to slow or stop it refilling each time we eat .
I think of it as one step forward using up glucose versus 2 steps back if we add more carbs then our meters say we can handle .
The idea of the 2 mmols or less increase is where type 2's try to mimic a non type 2's glucose response .
A long winded reply, but I hope of some use seeing the difference between type 2 & non type 2.
Good luck finding your answers.
