Got blood work done for life insurance. My levels look like I have pre diabetes. What can I do to either lower my levels or prevent full blown diabete?

Prediabetes. Medications are not necessary for prediabetes, only lifestyle measures such as high fiber diet with complex carbohydrates, smaller more frequent meals, leaner proteins, regular aerobic exercise and weight training and weight reduction if necessary. Supplementing cinnamon and chromium can help as well.
