Abstract
Ten observational studies and eight clinical trials were included in the systematic review.
- Four observational studies indicated a positive association between large evening meals and higher body mass index (BMI).
- Five observational studies found no association between evening energy intake and BMI.
- One observational study reported an inverse relationship between evening intake and BMI.
- The meta-analysis of observational studies revealed a non-significant trend regarding BMI and evening intake (P=0·06).
- The meta-analysis of intervention trials demonstrated no significant difference in weight change between small and large dinner groups (-0·89 kg; 95% CI -2·52, 0·75, P=0·29).
- Recommendations for reducing evening intake to achieve weight loss are not supported by the current clinical evidence.
