Healthy Lifestyles in Bipolar Disorder: Bay Area Study (NCT06555406)

๐ŸŸข Recruiting Observational / Diagnostic ๐Ÿง  Behavioral & Psychological Program Sponsor: University of California, Berkeley

๐Ÿฉบ Plain-English Summary (8th-Grade Level)

The goal of this clinical trial is to understand how level of adherence with time-restricted eating (TRE) predicts change in diurnal rhythms (as measured using the amplitude of diurnal peripheral clock gene expression), and how those changes predict lower mania and depressive symptoms, and downstream improvements in quality of life. The effects of diurnal amplitude of clock gene expression is expected to remain significant when controlling for change in glucose tolerance and inflammation. Participants will be enrolled who are already receiving medication treatment for bipolar disorder. Participants will complete daily measures of eating, sleep and mood for two weeks, and then will be assigned to follow TRE for eight weeks. Symptoms and Quality of Life will be measured at baseline and during and after the food plan.

Who can join: To join this study, participants generally need to meet the listed inclusion criteria (12 items) and avoid the listed exclusions (9 items).

Location: University of California Berkeley โ€” Berkeley, California
