Sponsor's own description

This research will test whether a standard version or very low-carbohydrate version of the Diabetes Prevention Program better improves outcomes like blood glucose control and body weight for patients with prediabetes. Participants will have screening (includes blood draw) and baseline testing with a continuous glucose monitor. Once these enrollment steps are completed and the participants will be randomized to one of two groups: standard National Diabetes Prevention Program (NDPP) or a very low-carbohydrate version. In addition to the diet (12 months) participants will be asked to participate in hour-long weekly group classes over zoom. After four months in the program, classes will occur about every month to help participants maintain the new diet. There will also be check-ins and follow-up visits through out the study.
