One's choice of diet and personal b.g goal is specific to each indivdual but i have found this site particularly useful as it offers alternative suggestions for control.
On diagnosis i was told to ditch all white carbs in favour of whole brown carbs and to limit those and, more, to always eat some form of protein with whichever carbs i did eat.
Currently i follow a much reduced carb regime but in no way is it a low-carb diet when compared to the low-carb version very popular with many members here. My blood glucose levels are usually pretty good, though.
I think it's a matter of testing, adjusting, experimenting and tweaking until you hit upon something you think you can live with and enjoy whilst maintaining acceptable b.g. levels. And even then, some days those levels can go all over the shop for no apparent reason! Exercise and general health seem to play a role here but even so, there are days when the body literally seems to have a will all its own!
Testing is the way forward - and gaining an understanding of how you feel at various levels - at which point do you start to feel 'low', for instance? Are you aware of feeling 'high'? It's good to try to discover that, if possible.
And as with everything, research, practice and ultimately, make an informed decision on how you want to control this disease. It's your body and you have responsibility for it, LOL. The only right way to deal with it is the way you feel happiest with.
