Effects of intermittent fasting combined with resistance training on body composition: a systematic review and meta-analysis

Methodology

Meta-analysis

Population

Studies comparing IF + RT vs non-IF + RT

Intervention

IF + RT vs non-IF diet + RT

Findings

Intermittent fasting produced similar body-composition changes to non-fasting diets when protein and calories were matched, alongside resistance training. Intermittent fasting is a viable strategy but not superior to continuous energy restriction; adherence remains the key determinant.

Outcome measures

Body composition (fat mass, lean mass)

Limitations

Limited studies; heterogeneity in IF protocols; varying RT protocols.
