At 200 pounds I'm guessing you want to lose weight. Although I don't know your age or height I'd guesstimate that you want to strive for around 1600 calories minimum (possibly more or less depending on your age, activity level, etc.) and an hour of daily exercise, in order to lose weight without losing your existing muscle mass. Exercise is one of the best things you can do as a diabetic, regardless of Type-I or Type-II. Not only does it burn existing blood glucose, it helps one lose weight, improves insulin resistance, enhances your mood and metabolism, and more.
Do your best to eat as low carb as possible. By doing so you'll need less insulin, have less chance of hypos, etc. Get the vast majority of your carbs from Vegetables, with the exceptions of Potato, corn and parsnips. Salad and green leafy vegetables are awesome. Avoid dressings/condiments/etc. with carbohydrate or sugars. Avoid refined products, especially anything made with 'enriched white flour' ...
In fact, do your best to avoid all flour, cereal, grain, rice, etc. Everything with carbs eventually becomes glucose, period. Most people controlling their sugars well are way under 100g of carb per day. The folks on this forum doing the best seem to keep it under 60g per day. That's a good goal to shoot for. (Yes, my signature says I eat more than that, but I eat more than most, and burn it all off, and then some...)
