🩺 Plain-English Summary (8th-Grade Level)
This is a clinical trial assessing the effects of fasting on the immune system in healthy adults. Immune profiling, gene expression profiling, and flow cytometry on peripheral blood mononuclear cells (PBMCs) will be performed and we hypothesize that a period of fasting will alter the immune system in healthy adults.
