Althought CLA increases muscle and reduces fat in developing mice and rats, it does not cause weight loss in humans according to a 1999 study.
?In pigs and cattle and in laboratory rats and mice, CLA [Conjugated Linoleic Acid] can increase the amount of muscle and decrease the amount of fat the animals develop as they grow,? says University of Wisconsin?s obesity researcher Richard Atkinson, M.D. However this doesn?t seem to be the case in humans.
Atkinson and his colleagues gave 80 very obese people 3 grams of CLA per day or a placebo. After nine months the study was stopped when it became clear that those taking CLA were not losing any more weight than those taking the placebo.
?It appears that CLA is unlikely to be effective for inducing weight loss,? said University of Wisconsin?s CLA-discoverer and researcher Mike Pariza. However, as of 1999, Pariza still believes that CLA may help people gain more muscle and less fat during weight regain. The next article shows this is so.
