Data Sheet 1_Effects of time-restricted eating on body composition and performance in athletes: a systematic review and meta-analysis.docx Ruting Lin (21169554) Yubo Wang (556762) Zhenyu Shuai (23095375) Kaixiang Zhou (1533451) Wenqiang Wu (643813) Clinical and Sports Nutrition athletes body composition Meta-analysis performance time-restricted eating Background<p>Time-restricted eating (TRE) has gained increasing attention as a dietary strategy for body mass management and metabolic health. However, its efficacy in athletic populations remains unclear. Therefore, this systematic review and meta-analysis aimed to examine the effects of TRE on energy intake, body composition, and performance in athletes.</p>Methods<p>Following PRISMA guidelines, the review was registered in PROSPERO (CRD420261291351). Six databases were searched from inception to January 10, 2026. Randomized controlled trials comparing TRE with non-TRE dietary patterns in adult athletes were included if they reported body composition or performance outcomes. Pooled effects were estimated as standardized mean differences (SMDs; Hedges’ g) with 95% confidence intervals (CIs) using random-effects models. Risk of bias was assessed using RoB 2 and evidence certainty using GRADE.</p>Results<p>Sixteen studies from 15 articles involving 245 athletes were included. TRE did not significantly alter energy intake (SMDpooled = −0.35, 95%CI: −0.77 to 0.07, p = 0.11). Compared with non-TRE dietary patterns, TRE resulted in small but significant reductions in body mass (SMDpooled = −0.27, 95%CI: −0.50 to −0.04; p = 0.02) and body fat% (SMDpooled = −0.39, 95%CI: −0.68 to −0.11, p = 0.01), while fat mass (SMDpooled = −0.23, 95%CI: −0.48 to 0.02, p = 0.07) and lean mass (SMDpooled = −0.16, 95%CI: −0.42 to 0.09, p = 0.21) were unchanged. TRE had no significant effects on aerobic capacity (SMDpooled = 0.04, 95%CI: −0.29 to 0.37, p = 0.82), muscular endurance (SMDpooled = −0.20, 95%CI: −0.52 to 0.13, p = 0.23), muscular strength (SMDpooled = 0.01, 95%CI: −0.25 to 0.27, p = 0.94), or power (SMDpooled = −0.12, 95%CI: −0.44 to 0.20, p = 0.47). Subgroup analyses suggested potentially greater reductions in body mass and body fat% among elite athletes, although between-subgroup differences were not statistically significant. Certainty of evidence ranged from very low to moderate.</p>Conclusion<p>TRE may represent a feasible dietary strategy for athletes seeking modest reductions in body mass and body fat% without clear detrimental effects on performance. However, evidence remains limited by small samples, short interventions, and methodological concerns, warranting larger, well-controlled, and longer-term trials across diverse athletic populations.</p>Systematic review registration<p>PROSPERO unique identifier CRD420261291351.</p> 2026-09-23T16:25:20Z Dataset Dataset 10.3389/fnut.2026.1956159.s001 https://figshare.com/articles/dataset/Data_Sheet_1_Effects_of_time-restricted_eating_on_body_composition_and_performance_in_athletes_a_systematic_review_and_meta-analysis_docx/33974440 CC BY 4.0
