Overview
This study is being done to assess the feasibility and acceptability of a time-restricted eating intervention among postpartum women with overweight/obesity.
Description
Existing postpartum weight retention (PPWR) interventions have had limited success. Timing-based interventions, such as early time-restricted eating (eTRE), show significant improvements in cardiometabolic endpoints in non-postpartum cohorts. The purpose of the Time4Mom study is to conduct a pilot randomized trial of a postpartum-adapted eTRE intervention to test feasibility and acceptability of the eTRE intervention and trial protocol. We will also compare changes in clinical outcomes of interest and patient-reported outcomes between eTRE (intervention) and control groups.
This 2-arm trial will randomize 60 postpartum women to either Control or eTRE for 12 weeks (n=30/group).
