There is strong scientific data that supports that short-term protein restrictive diets reduce surgical stress responses. The investigators are hoping to use the information collected from the blood serum and muscle tissue of healthy subjects to help understand the baseline and early changes in muscle energetic and cell-mediated inflammation. The study team hopes to use the data collected in this pilot study to compare with patients undergoing open abdominal aortic aneurysm (AAA) repair in a future study


Modulation of a patient's diet, specifically via short-term dietary protein restriction, can impact changes in cell energetics and dampen the normal subclinical inflammatory state. These changes can provide benchmarks for future research focused on using nutritional interventions aimed at improving the probability of a successful outcome following open aortic aneurysm surgery. The investigators will conduct a short term dietary restriction protocol to characterize these changes in a normal control cohort to be compared to patients which undergo surgery, to identify the optimal time points for sampling in the surgical population. These changes will be characterized by looking at inflammatory cells in the blood, proteins excreted in the urine, changes in microbiome signature identified by stool sample and oral swab, as well as changes in muscle energetics in small muscle biopsies.
