actually this worked for me, I had high blood sugar and high blood pressure and I solved both with low carbs diet and eating healthy. It's like the article say, eating healthy will help no matter what but yeah it's hard to stop eating junk.
there's no junk food.
there's nothing junky in a hamburger. on the other hand, it is unhealthy if you eat hamburger every day or so.

here's american diabetes association recommending a normal healthy high-carb diet with low GI foods.
it is also advised, funnily, that fruit consumption shouldn't be restricted.
