It's the same ol', same ol' progressive disorder so many of us have, and now that you see the pattern in your family, you have a leg up in managing it.
She doesn't need to wait for a diagnosis - she can always adjust her diet and pursue a good exercise regimen, lose weight if necessary, and she can also get a cheap meter & a few strips to check herself now & then for postprandial spikes (after meals is one of the first places it begins to show). Levels in a non-diabetic person would stay between 70-120 regardless of their intake, and if she began seeing readings outside of that range - hightail it to the doc with her evidence on the meter. Whether or not she would want to keep a food journal now, would be up to her, but I think if she began to have any suspicions, then keeping track would be good as ammunition to show the doc.
If it can't be prevented, it can sure be postponed, and all it takes is eating/exercising as though she already has it. Right now all she has is the predisposition to it, but that can be thwarted sometimes for awhile.
