This systematic review and meta-analysis examined the synergistic impact of time-restricted feeding (TRF) combined with resistance training (RT) (TRF + RT) on body composition and metabolic health in adults, contrasting it with habitual eating patterns (CON) and RT (CON + RT).
Adhering to PRISMA guidelines, five databases were searched up to 28 April 2024. Randomized controlled trials or crossover trials assessing the effects of TRF + RT for at least 4 weeks in adults were selected. Data were pooled as standardized mean differences (SMDs) or weighted mean differences (WMDs) with 95% confidence intervals (CIs). The risk of bias was evaluated using the revised Cochrane risk-of-bias tool.
Seven studies with 164 participants were included in the final analysis. TRF + RT significantly reduced body mass (WMD -2.90, 95% CI: -5.30 to -0.51), fat mass (WMD -1.52, 95% CI: -2.30 to -0.75), insulin (SMD -0.72, 95% CI: -1.24 to -0.21), total cholesterol (WMD -9.44, 95% CI: -13.62 to -5.27), low-density lipoprotein cholesterol (LDL-C) (WMD -9.94, 95% CI: -13.47 to -6.41), and energy intake (WMD -174.88, 95% CI: -283.79 to -65.97) compared to CON + RT. No significant changes were observed in muscle mass, strength, or other metabolic markers.
TRF + RT, in contrast to CON + RT, significantly improved body composition, insulin, and cholesterol levels without affecting muscle mass or strength.
本系统评价和荟萃分析考察了限时进食（TRF）联合抗阻训练（RT）（TRF + RT）对成年人身体成分和代谢健康的协同影响，将其与习惯性进食模式（CON）和 RT（CON + RT）进行对比。
根据 PRISMA 指南，检索了五个数据库，截至 2024 年 4 月 28 日。选择了至少持续 4 周的 TRF + RT 对成年人影响的随机对照试验或交叉试验。使用标准化均数差值（SMD）或加权均数差值（WMD）及其 95%置信区间（CI）进行数据合并。使用修订后的 Cochrane 偏倚风险工具评估偏倚风险。
最终分析纳入了 7 项研究共 164 名参与者。TRF + RT 可显著降低体重（WMD -2.90，95%CI：-5.30 至 -0.51）、体脂（WMD -1.52，95%CI：-2.30 至 -0.75）、胰岛素（SMD -0.72，95%CI：-1.24 至 -0.21）、总胆固醇（WMD -9.44，95%CI：-13.62 至 -5.27）、低密度脂蛋白胆固醇（LDL-C）（WMD -9.94，95%CI：-13.47 至 -6.41）和能量摄入（WMD -174.88，95%CI：-283.79 至 -65.97），与 CON + RT 相比。肌肉质量、力量或其他代谢标志物没有显著变化。
与 CON + RT 相比，TRF + RT 可显著改善身体成分、胰岛素和胆固醇水平，而不影响肌肉质量或力量。
