Abstract
Past iterations of the Diabetes Prevention Program (DPP) have demonstrated success in reducing the risk of developing type 2 diabetes in high-risk individuals, including studies that focused on low-carbohydrate or ketogenic approaches. The program emphasizes dietary modifications, physical activity, and behavioral strategies to promote weight loss and improve metabolic health. While the traditional DPP focuses on a low-fat, calorie-restricted diet, there is growing interest in exploring alternative dietary approaches, such as vegetarian diets, which have shown promise in improving glycemic control and reducing cardiovascular risk factors. This study aims to evaluate the effectiveness of a 6-month vegetarian DPP in individuals with prediabetes. The study included 7 participants initially, but 2 dropped out, resulting in a final sample size of n=5. The program consisted of 16 sessions led by 2 certified DPP coaches, with a curriculum focused on education about healthy vegetarian diets, exercise, and lifestyle modifications. The primary results showed that while there was a slight decrease in weight and hemoglobin (Hb)A1c levels, these changes were not statistically significant, suggesting the need for further research with larger sample sizes and longer durations to validate these findings.
