What is the best way to help improve my glucose levels ?

Exercise, Metformin: First, avoid carbs--simple and complex (complex carbs are metabolized into glucose). Exercise daily--you don't need to kill yourself--a 15 minute walk each day works wonders for blood sugar. Metformin is the drug of choice for diabetes--but is great for those with borderline blood sugars as well. It's one of the best weight loss drugs there is. It will not cause hypoglycemia.
