1. Try a low carb & low glycemic index diet. Calories are important, but the number of grams of carbs/serving are more important. You might be suprised how little one serving is of some foods
2. Exercise at least three times/week. I am on my ellipitical for 35 mins at least 3 times/wk
3. Do your own research. There are some well meaning people on this board, but some of them don't know shit
After I was diagnosed w/ DMII my dietician put me on a low carb/low glycemic diet in addition to the oral meds I was prescribed. I can eat almost anything I want - I just had to eat the right foods & also cut down on my portions. I am 6' 3" and when I was diagnosed I weighed 218 lbs - not overweight at all - and there was no history of diabetes in my family. Now, four years later I weigh around 180 and my A1C is consistently below 7.
...Being diabetic is not a death sentence in an of itself. You just have to work at controlling your blood glucose levels & A1C and you'll be fine.
