Summary We performed a systematic review and meta‐analysis to investigate the effect of resistance training (RT) with and without caloric restriction (CR) on visceral fat (VF). PubMed and Scopus were searched to identify original articles published through December 2020. Standardized mean differences and 95% confidence intervals (95% CIs) were determined, and separate analyses were conducted for RT versus control, and RT plus CR versus CR only. Thirty‐four studies including 38 intervention arms and involving 2285 were included in the meta‐analysis. RT effectively reduced VF [−24 (95% CI −0.34 to −0.13), p < 0.001; I 2 = 4.17%, p = 0.40; 24 intervention arms] when compared with control. Based on subgroup analyses, reduction in VF was significant for individual with ( p = 0.04) and without ( p < 0.001) obesity as well as across medium‐term ( p = 0.001) and long‐term ( p = 0.002) interventions. Reduction in VF was significant for both middle‐age ( p = 0.03) and elderly ( p = 0.001) adults but was not significant for pediatric ( p = 0.08) participants. However, RT plus CR did not indicate superiority effect on VF [0.23 95% CI −0.04 to 0.51, p = 0.09; I 2 = 58.76%, p = 0.003; 14 intervention arms] when compared with CR only. Our results confirm that RT may be effective for reducing VF, but adding RT with CR was not associated with a greater effect for reducing VF.
