Green tea (GT) is a common component of supplements known as fat burners. It has gained popularity as an ergogenic aid for weight reduction to assist with obesity management. This systematic review and meta-analysis aim to explore the effect of green tea ingestion coupled with exercise training (EX) on body composition and lipid profile in overweight and obese individuals.
Two independent researchers systematically searched the electronic databases of PubMed, Web of Science, and Scopus. Studies with a randomized-controlled design to compare the effect of green tea in conjunction with exercise training (EX+GT) versus exercise training alone (EX+P) in overweight or obese participants were included.
Of the 1,015 retrieved studies, 24 were identified to undergo full-text review, out of which 10 randomized trials met the inclusion criteria. EX+GT versus EX+P had a small and consistent effect on weight [Standardized mean difference (SMD) = -0.30, CI: -0.53 to -0.07], BMI [SMD = -0.33 CI: -0.64 to -0.02] and fat reduction [SMD = -0.29, CI: -0.57 to -0.01] and there was no evidence of heterogeneity across the trials. When compared to EX+P, EX+GT had no greater effect on lipid profile improvement [triglyceride: SMD = -0.92, CI: -1.30 to 0.49; LDL: SMD = -1.44, CI: -0.73 to 0.82; HDL: SMD = 0.56, CI -0.71 to 0.46; and total cholesterol SMD = -0.54, CI -0.85 to 0.13].
Current evidence suggests that green tea could have quite minimal additive benefit over exercise-induced weight loss. However, incorporation of green tea into exercise training does not seem to exert additional benefits on lipid profile and it warrants further investigations in the future.
绿茶（GT）是一种常见的补充剂成分，被称为脂肪燃烧剂。它作为一种减轻体重的运动辅助剂而广受欢迎，有助于肥胖管理。本系统评价和荟萃分析旨在探讨在超重和肥胖个体中，摄入绿茶结合运动训练（EX）对身体成分和血脂谱的影响。
两名独立研究人员系统地检索了 PubMed、Web of Science 和 Scopus 电子数据库。纳入了比较绿茶与运动训练（EX+GT）联合与运动训练（EX+P）单独对超重或肥胖参与者影响的随机对照设计研究。
从检索到的 1015 篇研究中，有 24 篇被确定进行全文审查，其中 10 项随机试验符合纳入标准。与 EX+P 相比，EX+GT 对体重[标准化均数差（SMD）=-0.30，CI：-0.53 至-0.07]、BMI[SMD=-0.33，CI：-0.64 至-0.02]和脂肪减少[SMD=-0.29，CI：-0.57 至-0.01]有较小且一致的影响，并且各试验之间没有异质性。与 EX+P 相比，EX+GT 对血脂谱改善没有更大的影响[甘油三酯：SMD=-0.92，CI：-1.30 至 0.49；LDL：SMD=-1.44，CI：-0.73 至 0.82；HDL：SMD=0.56，CI：-0.71 至 0.46；总胆固醇 SMD=-0.54，CI：-0.85 至 0.13]。
目前的证据表明，绿茶对运动引起的体重减轻可能只有很小的额外益处。然而，将绿茶纳入运动训练似乎不会对血脂谱产生额外的益处，这需要在未来进一步研究。
