Chronobiology of Meal Timing: Effects on Vascular and Renal Function

Despite advancements in pharmacologic antihypertensives, hypertension currently affects 1 in 3 Americans and accounts for more than $50 billion of health care spending. Importantly, hypertension is the leading cause of cardiovascular (CVD) and kidney diseases (CKD). As a result, the AHA/ACC lowered the diagnostic criteria for hypertension to encourage earlier preventative lifestyle intervention. There is a critical need to identify and implement novel lifestyle interventions in individuals with early-stage hypertension to prevent the subsequent development of CVD and CKD. Chronotherapy that aligns behavioral cues (such as time of eating) with the body's internal biological clocks, has gained much attention as a potential strategy to prevent and manage hypertension, however, the underlying mechanisms are not yet fully understood. The purpose of this study is to investigate the effects of mistimed eating on blood pressure, kidney function and vascular function.
