Misty, you bring up an interesting point about
'borderline' diabetes. Many doctors will say if your fasting is between 100 and 125 that you're 'borderline'. It's the same thing with 'insulin resistant'. (That term probably describes all type 2s.) Personally, I also think it's all diabetes. Some people can still control diabetes with diet and exercise; others need oral meds and still others need insulin maybe with other meds. But it's all diabetes to me, too.
In all cases, I believe we benefit from food and lifestyle adjustment.
