I think most of the confusion comes in what actually is a sensible diet. THEY, tell us low fat is healthy, but fats are neutral in diabetes. To lower your blood glucose you need to lower your carbs. That is anything that started off as a grain [bread, cakes, breakfast cereals, pasta, biscuits etc and most underground vegetables, like potatoes, parsnips etc and anything sweet. fortunately reducing your carbs will reduce your weight too.
In addition, it's helpful to reduce your total food intake. Except green leaves which you can eat as much as you like.
That's the simple version. If it works for you[ and it WILL],you can learn more as you go on. You wil be amazed at what delicious stuff there is left to eat.
Hope that helps
