This systematic review and meta-analysis evaluated the influence of intermittent fasting (IF) in combination with resistance training (RT) on body composition outcomes. Studies examining IF vs. non-IF diets in individuals performing RT, published up to February 2021, were identified through PubMed, the Cochrane Library, Web of Science, Embase, and SCOPUS databases. Eight studies, including 221 participants were analyzed using a random-effects model to calculate weighted mean differences (WMDs) with 95% confidence intervals (CIs). Results indicated that IF had a significant effect on body mass (WMD = -2.08 kg; 95% CI: -3.04, -1.13), fat mass (WMD = -1.36 kg; 95% CI: -1.94, -0.78), body mass index (WMD = -0.52 kg/m²; 95% CI: -0.85, -0.19), and body fat percentage (WMD = -1.49%; 95% CI: -2.24, -0.74) relative to non-IF diets, without a significant effect for fat-free mass (WMD = -0.27 kg; 95% CI: -0.82, 0.28). The present systematic review and meta-analysis demonstrates potentially beneficial effects of IF in combination with RT for reducing body mass and body fat relative to non-IF control diets, with similar preservation of fat-free mass.

这项系统的回顾和荟萃分析评估了间歇性禁食（IF）结合抵抗训练（RT）对身体成分结局的影响。通过PubMed，Cochrane图书馆，Web of Science，Embase和SCOPUS数据库，鉴定了截至2021年2月发表的关于进行RT的个人中频与非中频饮食的研究。八项研究（包括221名参与者）使用随机效应模型进行了分析，以计算具有95％置信区间（CI）的加权平均差异（WMD）。结果表明，中频对身体质量（WMD = -2.08 kg; 95％CI：-3.04，-1.13），脂肪质量（WMD = -1.36 kg; 95％CI：-1.94，-0.78）有显着影响质量指数（WMD = -0.52 kg / m ²; 相对于非中频饮食，95％CI：-0.85，-0.19）和体脂肪百分比（WMD = -1.49％; 95％CI：-2.24，-0.74），对无脂食物（WMD）无明显影响＝ -0.27kg； 95％CI：-0.82，0.28）。本系统的综述和荟萃分析表明，与非中频对照饮食相比，中频与逆转录酶联用对减少体重和体内脂肪具有潜在的有益作用，并且保留了类似的无脂肪量。
