NCT01755962

Brief Summary

This project is prompted by the urgent public health need to identify novel strategies to prevent cardiovascular disease (CVD) and type 2 diabetes (T2D). The higher prevalence of CVD, T2D, and metabolic syndrome in obese individuals is a major healthcare concern. Therefore, finding optimal intervention strategies to combat these growing epidemics is imperative.
