Effects of Prolonged Fasting on Microbiome and HDL

Participants will undergo one day of habitual eating followed by 36 hours of water-only fasting and final day of habitual eating consuming the exact same diet consumed on the first eating day. Blood draws will be performed on Day 1 in a 10-12 hr fasted state and 2 hour postprandial state and again on Day 3 in a 36hr fasted state and a 2 hour post prandial state. Microbiome samples and blood glucose data will be collected throughout the course of the study.
