Official title
Pilot Study to Evaluate the Effect of Fasting and Refeeding on T-Cell Fate
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Background: Researchers want to better understand the body s immune response to calorie restriction. To do this, they are asking healthy volunteers to fast for 24 hours. Researchers will test immune response before and after fasting. Objectives: To explore the benefits of calorie restriction on immune health. Eligibility: Healthy volunteers ages 21 to 37 with a body mass index between 22 and 29. Design: Participants will be screened with medical history, physical exam, and blood tests. Participants will visit NIH after an overnight fast. Their baseline immune response will be taken. They will give blood and urine samples. Then they will be given breakfast. This visit will take about 2 hours. Participants will fast (not eat or drink anything except water) for the next 24 hours. They will return to NIH the next morning. Their immune response will be taken. They will give blood and urine samples. Then they will be given breakfast. Their immune response will be taken 3 hours later. They will give a blood sample. This visit will take about 4 hours.
