Summary
This systematic review analyzed 28 RCTs (n=2,156) comparing time-restricted eating (TRE) with ad libitum eating. TRE protocols (8-10 hour eating windows) showed modest but significant reductions in body weight (-1.6 kg), fasting insulin (-12%), and systolic blood pressure (-4 mmHg).
Key Findings
1. Average weight loss of 1.6 kg over 8-12 weeks
2. Fasting insulin reduced by 12% on average
3. Effects independent of caloric restriction in 40% of studies
4. 8-hour eating window showed optimal balance of adherence and efficacy
