CLA 用于 肥胖症
B 证据 至少一项随机试验支持这一结论，结果基本一致。Cochrane meta-analysis of 18 RCTs (n=807) found CLA at 3.2 g/day reduced body fat mass by 1.33 kg over 6-12 months without significant change in body weight, suggesting lean mass preservation. A 2-year RCT (n=134) found sustained fat reduction. Effects are modest and require long-term use.
