What can I expect to happen during the study?
We will ask you to visit our research center twice:
1. for an explanation of the study and about 4 hours of testing
...and about 2 weeks later...
2. for a full day of testing (7:00 am-4:30 pm).
Tasks: We will measure your body size, vital functions, and metabolism. There will be a 3 min physical fitness test, full-body radiology scan, taste tests and a forced exhale test. At home, we ask that you complete 3 diet activities and wear an activity monitor for 7 days. After a 12 hour fast, we will provide you a liquid meal and afternoon snack at the WHNRC. You will be asked to wear an electric monitor, answer 5 surveys about your lifestyle (food choices, physical activity, stress, etc.), complete 4 computer-based activities, and wear a tight blood pressure cuff for 5 min. We will also collect: breath, saliva, blood, urine, and stool.
