That's not how type 2 works. The resistance is developed for unknown reasons and it continues to build over time. For a while, your body can compensate by producing more insulin to overcome the insulin resistance of your cells. You don't become symptomatic until your cells are almost completely insulin resistant. Your pancreas will continue to make insulin at crazy high rates, but eventually the cells that make insulin will die off (presumably from hyperactivity). This is the point at which type 2 diabetics need insulin.

As far as cutting sugar out of your blood - you can't. Your body tries to maintain 80-110 mg/dL of sugar in your blood. You NEED sugar. It's energy. In fact, sugar is the ONLY energy source your brain can use. The problem is when you're a diabetic, your body's cells can't take that sugar out of the blood to use it for energy. That's when you try to minimize your sugar intake, because if you don't, you can do irreversible damage to your nerves and vasculature.
