Participant Flow

Participants were recruited based on physician referral at a single academic center between November 2020 and February 2023. The first potential participant screened for study eligibility was on December 3, 2020 (enrolled (randomized) December 17, 2020) and the last participant screened for eligibility was in February 2023.

Out of 85 potential participants screened for study eligibility, 61 met the inclusion criteria and were subsequently randomized to treatment. One participant was excluded from analysis because of an underlying muscular dystrophy known to affect body composition.

Measure
Standard of Care (SOC)
Participants will receive standard of care nutritional behavioral counseling and will be required to log their caloric intake through the use of a smartphone app. Standard of Care: Participants in this arm will receive nutritional counseling from the study dietician but will not be required to adopt a 10-hr eating window.
TRE + SOC
Participants in this arm will receive standard of care nutritional behavioral counseling and will implement a daily, self-selected, 10-hour window within which they must consume all calories. They will also be required to log their caloric intake through the use of a smartphone app Time Restricted Eating: Participants in this arm will adhere to a daily, consistent self-selected 10-hr eating window for the course of the study intervention period as well as receive nutritional counseling from the study dietitian.
