Hi Jonty.
it's nearly always borderline type 2 with the NHS as they automatically assume most people are type 2 even when they might not be! Two fasting BG levels of over 7 mmol is diagnostic of diabetes so if you get consistent morning readings of 7 or above its actually enough to be diagnosed as diabetic.
Finding out ur pre diabetic though is good because it means you have time to turn things around before you need any meds or anything (presuming you are type 2 of course)
Also, everyone is different when it comes to tolerances. Flour is actually ALOT worse for my BG than sugar is! If I eat a wrap or something like that I am over 10mmol (hence why i don't eat them) but when I have the odd chocolate or something like that I rarely go above 9!
It depends alot on the fat content too... I ate a mars bar the other day (in rebellion, no excuses I'm afraid) and I was 9.3mmol afterwards but when I had a few chips one day at my mother in laws house (and I mean a few) I was 14.4mmol 2hrs later! That is literally how different people can be with diabetes lol
