What this trial studies

This pilot randomized two-arm trial will enroll 60 postpartum women (6–16 weeks after a healthy singleton birth) with BMI ≥25 and randomize them 1:1 to a 12-week early time-restricted eating (eTRE) intervention or a control group. The eTRE approach is adapted for postpartum life and limits daily eating to an earlier daily window, while the control arm receives usual care. Primary aims are to measure feasibility and acceptability of the intervention and trial procedures, with secondary comparisons of clinical outcomes (weight and cardiometabolic markers) and patient-reported outcomes. Participants with major medical conditions, diagnosed eating disorders, recent extensive fasting, or other exclusion criteria will be excluded from enrollment.

Who should consider this trial

Good fit: Ideal candidates are postpartum women 6–16 weeks after a healthy singleton birth with BMI ≥25 who can consent, communicate in English, and do not meet any exclusion criteria.

Not a fit: Patients with major medical conditions such as diabetes or renal disease, diagnosed eating disorders, current use of weight-altering medications, frequent overnight shift work, regular long fasting habits, or current participation in another dietary/weight program are unlikely to benefit or are excluded.

Why it matters

Potential benefit: If successful, this could offer a simple timing-based approach to help postpartum women with overweight or obesity lose weight and improve cardiometabolic health.

How similar studies have performed: Early time-restricted eating has shown cardiometabolic benefits in non-postpartum adult studies, but applying eTRE specifically in postpartum women is relatively novel and not well tested.
