First -I don't understand why people continue to pass along the myth that too many carbs causes DM and that cutting carbs to extreme levels is the way to go!
I can't pm you TK is saying
skin not found WTF? Anyway, 30 grams a day of CHO sounds terribibly low to me and I have never heard (in my educational learning) that cutting CHO intake like this will prevent DM2. You need carbs to function and 30 grams a day is impossible. I suggest you go see a
Registered Dietitian who specializes in Diabetes. Doctors are great for medical advice but they don't have the extensive background in food and nutrition like we do. In fact, the American Dietetic Association is trying to get a bill passed (I think?) where it will be required that we will be the main person to go to for nutrition advice and nutrition prescriptions.
Here is a book the American Diabetic Association suggests

Glycemic index.
Although low glycemic index diets may reduce postprandial glycemia, the ability of individuals to maintain these diets long-term (and therefore achieve glycemic benefit) has not been established. The available studies in persons with type 1 diabetes in which low glycemic index diets were compared with high glycemic index diets (study length from 12 days to 6 weeks) do not provide convincing evidence of benefit. In subjects with type 2 diabetes, studies of 2–12 weeks duration comparing low glycemic index and high glycemic index diets report no consistent improvements in HbA1c, fructosamine, or insulin levels. The effects on lipids from low glycemic index diets compared with high glycemic index diets are mixed.
Although it is clear that carbohydrates do have differing glycemic responses, the data reveal no clear trend in outcome benefits. If there are long-term effects on glycemia and lipids, these effects appear to be modest. Moreover, the number of studies is limited, and the design and implementation of several of these studies is subject to criticism.
Fiber.
I am not saying don't listen to your doctor but you NEED a second opinion for sure. I am not an RD YET so please go see the RD I have suggested for real, sound advice :P
HTH!
