Quoting Derpy the Duck:" So, I was diagnosed with GD. My OB gave me a meter, lancets, and strips. He told me he wanted to see ... [snip!] ... groups and quit asking questions. Maybe I'm freaking myself out for nothing. Thoughts? Advice? Idk. Thanks for reading. "
I was just diagnosed with GD as well. I've also been diagnosed as Insulin Resistant for the last 10 years. The diets are basically the same. So I can help if you'd like.
You want your numbers to be under 110-120 (your diabetic counselor will give you more information) but that is a rough guesstimate. A good fasting level will be anywhere from 60-80. You check 4 times a day. Once in the morning before you eat and 2 hours after every meal.
Diet wise, you want to avoid simple sugars as much as possible and you need to start reading package labels to tell you how many carbohydrates are in everything you eat. Again, your diabetic counselor will be able to give you specific numbers for how many carbs you're allowed in a day. Usually you will be allowed anywhere between 90 and 120 a day (30-40 a meal) depending on how bad your numbers are. You also want to cut any white, enriched wheat products out of your diet completely. That means switching to whole wheat pasta, brown rice, whole grain bread, etc. if you don't already do that. In general you can eat as much of any vegetable you want except for corn, and carrots as they are both full of sugar. If you're concerned that what you're eating may be too carb filled you can use this website as a resource www.carb-counter.org or you can always Bing or Google "how many carbs are in ___________. " When you're looking at packaged foods, you need to not only look at the carb content, but the sugar content. The more of the carbs are pure sugar, the more you will need to avoid that food to keep your numbers down.
I broke down and had a single serving of Lucky Charms for breakfast yesterday (according to the label on the package) and my numbers were HORRIBLE after breakfast. So, as much as you may want simple sugar, it may be best to avoid it all together if your numbers are really bad.
Good luck. I hope that you get into the diabetic counselor soon and can get a little more information.
