Effect of Nutritional Supplements (Ivital Control) on Clinical Outcomes in Patients With Prediabetes and Obesity：a Randomized Controlled Study

This study aims to improve blood glucose and weight in patients with prediabetes and obesity through health education, nutritional supplement interventions, clinical evaluation, and close clinical follow-up.100 patients with prediabetes with obesity were randomly divided into 2 groups: life intervention group, nutritional supplement intervention group. All enrolled participants were recommended for routine diabetes lifestyle education according to the "Expert Consensus on Prediabetes Intervention in Adults in China". The duration of the intervention was 3 months. The investigators aimed to compare the differences in weight, glycosylated hemoglobin, lipids and other indicators of the two groups of included populations before and after the intervention. In addition, the investigators are to explore the effects of nutritional supplement interventions on glycolipid metabolism and body weight in prediabetes with obesity.
