I hope so.
I've got my weight down, and my bg is regularly between 5 and 6, My cholesterol is better than it used to be, so if anything I'm a lot healthier than I used to be pre diagnosis.
The complications seem to be directly related to the effects of the glucose circulating around, so if you can keep this to a "normal" level, I hope you won't see any problems.
I suppose the big question is do the short term spikes cause major damage?
I test my un diabetic wife occasionally, and she has been in the 7's after eating, so I'm assuming the normal body copes with as least that, so avoiding anything over that short term seems to be a good strategy.
Whether you low carb, low GL, or any other way, eating to your meter seems the thing to do to avoid complications.
Exercise, healthy diet, and watching the weight should generally improve your chances of staying healthier as well.
