Welcome to the Forum!
Yes, dieting and diabetes is tough!
May I make a suggestion. Please read through the Blood Sugar 101 thread in the T2 Section. You may also like to take a look at the Carb Counting 101 thread. Since you are going to diet anyway, why not shoot for lower carbs. This will make a world of difference in your blood sugars and while you are controlling your blood sugar, with less carbs, the weight will just fall off. Just my two cents, your mileage may vary.
