Immunomodulatory Effects of Fasting in Healthy Adults

"The study will consist of two days of eating a controlled habitual diet and one 36-hour period of water-only fasting with glucose monitoring as a measure of compliance. Water intake will be limited to 2 liters/day to prevent electrolyte abnormalities. Subjects will undergo 4 separate blood-draws consisting of an overnight fasted sample (Baseline), a 2-hour postprandial sample (Fed), a 36-hour fasted sample (Fasted), and final 2-hour postprandial sample after the fasting period (Refed)."
