More studies studying CLA induced fat loss in humans have been published than referred to in this study. The large majority of high quality studies among these(meeting EFSA guidelines)do report fat-loss. However, the minimum time required to find such an effect in group sizes as most often used (10-20)is 12 weeks of daily exposure to CLA. This study had a duration of 8 weeks, and was therefore probably too short for finding a fat-loss effect of CLA in a study with this limited size.
