I'm pre-diabetic, both parents were Type 2. My testing supplies are cost covered if I attended a series of 3 classes with self help diabetic instructors. I recommend you look into this in your area. I grumbled about going, but learned a few things from it. Some of my classmates were really in the dark about their health. One man thought a pop tart was an acceptable snack, for gosh sake. He was having low blood sugar episodes in the night.
Simple Carbs are are not your friend. Count them faithfully and cut where you can. A hamburger without the bun or even half a bun is a start. The amount of sugar in foods is staggering so I read labels a lot and choose the one with less sugar, of course. One example is yogurt, some brands are loaded with sugar, so leave them in the store. Eat meals at regular time, you body loves to be on a routine. 2 healthy snacks a day keeps blood sugar stable.
I never drink fruit juice, but have tomato juice at breakfast. Pump up your fiber diet. Watch the processed foods, really none are good for you. Simple home cooked is what's best for anyone, diabetic or not. Pay close attention to feet, so you don't get a sore, then you could be in for trouble. I never cut my toe nails, I file them about 2x a week after a bath. I deal with diet pretty well, now if I could just exercise more.
