Study Background

The main question the Does What You Eat Affect Your Brain (WYE) study is exploring: Does the brain change after short-term diet changes, and can MRI detect these changes?

Participation will include 6 in-person study visits at UW South Lake Union (SLU): 1 screening visit, and if eligible, 5 study visits in the morning over 2 consecutive weeks, and 1 remote visit at 12 weeks. Procedures include blood draws, body measurements, x-rays, MRIs, questionnaires and eating only study foods for 2 weeks. The foods that are prepared for you may contain more or less than your estimated daily caloric need.
