Outcome Measures

Primary Outcomes (4)

  • Number of Participants With Treatment-Emergent Adverse Events as a Measure of Safety and Tolerability

    At each follow-up contact (either by phone or in person), participants are asked about any changes to their health or physical function since the previous contact. The changes are documented on the adverse event log.

    Week 4

  • Adherence

    Adherence to the study intervention is measured using food intake time diary. Participants are considered compliant to the study intervention if he/she fasts between 14 - 18 hours per day for the duration of the 4 week study.

    Week 4

  • Retention

    Number of Participants who dropped out before the Week 4 clinic visit was completed.

    Week 4

  • Recruitment Yields

    Recruitment yields is measured by the number of individuals who were assessed at phone screening.
