<qa>  What is the main reason for liraglutide?The objective of this study is to test the hypothesis that liraglutide commonly known as Victoza can promote an anti-inflammatory macrophage phenotype in human adipose tissue and blood, thereby reducing localized and systemic inflammation which are risk factors for cardiovascular disease and may contribute to hyperglycemia. This will be done after 4 weeks of treatment during which weight will remain stable, and again after 12 weeks, during which liraglutide-related weight loss occurs.
