Study Details

Brief summary:

The TWIST 2.0 Study is a 12-month, 2-arm RCT in adults with recent weight loss. We will examine the efficacy of TRE on weight (Aim 1a) and fat mass (Aim 1b) regain, and describe changes in subjective appetite following a mixed-meal tolerance test (Exploratory).

Interventions and Outcome Measures

Arms

experimental: Time-Restricted Eating (TRE)

Participants assigned to the intervention: ≤10-hour/day time restricted eating.

active comparator: Baseline Advice Control (CON)

Participants assigned to receive baseline advice.

Interventions

TRE

Participants randomized to the TRE arm will be instructed to consume all food and beverages in a self-selected 10-hr eating window.

Weight-Loss Maintenance Advice

The CON arm participants will receive written baseline advice following randomization assignment that includes determinants associated with long-term weight-loss maintenance success (e.g., physical activity, and strategies to limit calorie intake).

Primary outcome measure

  • Absolute Body Weight Change [ Time Frame: Baseline, Month 6, Month 12 ]
  • Percent Body Weight Change [ Time Frame: Baseline, Month 6, Month 12 ]
  • Percentage of Participants with Successful Weight Loss-Maintenance (WLM) [ Time Frame: Baseline, Month 6, Month 12 ]
  • Absolute Fat Mass Change Measured with DEXA [ Time Frame: Baseline, Month 6, Month 12 ]
  • Percent Fat Mass Change Measured with DEXA [ Time Frame: Baseline, Month 6, Month 12 ]
