If you want to lose weight AND reduce Bg numbers the best first step is to reduce your carbohydrate intake and your portion sizes. A little light exercise, say 30 mins a day also helps. Nothing too strenuous, just something that gets the Heart pumping ! You should soon see some improvements in both areas. .
Using that method, plus Byetta I have lost over 5 stone since January 2009. So it can and does work. NO, I do not low carb, before anybody asks or assumes....!
