We conducted a meta-analysis to assess the effect of green tea, caffeine and capsaicin supplements on the anthropometric indices in adults. PubMed/Medline, Scopus, Cochran and Web of Science databases were searched up to March 2017. Green tea significantly reduced weight by −0.65 kg (−1.10 to −0.20, P = 0.005), body mass index (BMI) by −0.26 kg/m2 (−0.43 to −0.10, P = 0.002) and waist circumference by −1.11 cm (−1.99 to −0.23, P = 0.01) but not percent of body fat (PBF) (−1.42%, 95% CI: −3.02 to 0.18, P = 0.08). Caffeine supplement had no effect on weight (−2.99 kg, 95% CI: −7.83 to 1.41, P = 0.18). We observed a significant weight loss after capsaicin supplement (−0.50 kg; 95% CI: −0.90 to −0.11, P = 0.01) but PBF did not change significantly from baseline (0.11%, 95% CI: −0.22 to 0.43, P = 0.51). Green tea and capsaicin supplements have a significant mild weight-lowering effect. On the contrary, it seems caffeine had no effect on weight.

绿茶,咖啡因和辣椒素补充剂对人体测量指标的影响:一项随机临床试验的荟萃分析

我们进行了荟萃分析,以评估绿茶,咖啡因和辣椒素补充剂对成人人体测量指标的影响。截至2017年3月,已搜索PubMed / Medline,Scopus,Cochran和Web of Science数据库。绿茶可将体重显着降低-0.65 kg(-1.10至-0.20,P = 0.005),体重指数(BMI)降低-0.26 kg /米2(-0.43至-0.10,P = 0.002)和腰围为-1.11 cm(-1.99至-0.23,P = 0.01),但不是人体脂肪(PBF)的百分比(-1.42%,95%CI:-3.02至0.18,P = 0.08)。咖啡因补充剂对体重没有影响(-2.99 kg,95%CI:-7.83至1.41,P = 0.18)。我们观察到补充辣椒素后体重明显减轻(−0.50 kg; 95%CI:-0.90至-0.11,P = 0.01),但PBF与基线相比无明显变化(0.11%,95%CI:-0.22至0.43,P = 0.51)。绿茶和辣椒素补充剂具有明显的轻度减肥作用。相反,咖啡因似乎对体重没有影响。
