Hello! Welcome to medhelp. Sorry you haven't gotten an answer to your question. Sounds like you are a very thoughtful person about your health which is great and cograts on losing some weight. I'm working on that myself! I have gotten into the DASH diet. It's recommended by the American Heart Association and is great for your health. However, it's really for prevention of hypertension, it's also good overall. So, for diabetes specific, there ARE dietary rules to follow. Here is a link to diabetes.org that discusses eating choices. http://www.diabetes.org/food-and-fitness/food/what-can-i-eat/
You may find that source really helpful. But in general, eat plenty of fiber, whole grains, eat more vegetables, have protein at your meals, be careful of alcohol (as you are) and limit sugar.
Most important is to maintain a healthy weight and to exercise. Let me know what other kind of info you'd like! I'm happy to try to help!
Best diet for people with prediabetes is one that is lower in carbs, with adequate protein and healthy fats for energy. Some people follow paleo or keto type diets. These also can work well, and reduce blood sugars / requirements for medications. Please do educate yourself well on these. The current trend for ketogenic diet is limit carbs, adequate protein and enough healthy fats to make up energy requirements.
