Is CLA conjugated linoleic acid effective for weight loss?
The results that made CLA popular where studies were done on mice (like most others) the issue from CLA is the source of CLA as an OTC supplement varies too much from company to company. The other issue which was not truly addressed was the amount of CLA needed for humans to see results. They say 3 grams per day but some studies I read about years back said the "mouse" studies actually were upwards of 6-8 grams per day which is costly and still not enough human testing to prove it made an impact on body fat.
Now from I remember it did have an anti-catabolic effect during lower calorie dieting so you kept more muscle while you lost fat do to diet and exercise.
I think it is a decent supplement just as a fatty acid but don't put too much stock in it burning off fat like it has been pushed for a couple of decades.
My 2 cents which in some small very poor countries that is worth about 1.6 cents
