The purpose of this study was to investigate the impact of combining aerobic exercise (AE) and vegetarian diet (VD) on blood pressure and body weight in adults with overweight and obesity. The PubMed, Web of Science, Scopus, and Google scholar databases were searched until February 2023 for English articles, and 1065 articles were found. Meta-analyses were performed to compare the impact of aerobic exercise and vegetarian diet on body weight, blood pressure in adults with overweight and obesity. Data analysis was performed using random effect model and weighted mean differences (WMD). The results of meta-analysis of 25 studies with 10192 adults showed that combined aerobic exercise and vegetarian diet significantly decreased in body weight [WMD=-4.63, p=0.001] , systolic blood pressure [WMD=-6.94, p=0.001] , and diastolic blood pressure [WMD=-4.5, p=0.001] , in adults with overweight and obesity. Aerobic training alongside vegetarian diet as a non-medication approach for weight loss and blood pressure control in adults with overweight and/or obesity. In addition, aerobic exercise and vegetarian diet with both types of duration (less than 12 weeks and more than 12 weeks) cause a significant decrease in blood pressure in adults with overweight and obesity.
