Nandi12, One thing you have to remember is that these studies more than likely did not use 2000-3000mg of ALA.
Ahhh, kick ass point Quadsweep. If you go to GNC or local vitamin shop they will usually tell you to only take a handfull of ALA pills each day. Thats why i would assume these scientists are only testing with low amounts of ALA. If you read what people's results on this board you will hear a lot of"when i upped my ALA dosage to 3000mg a day the fat flew off", so maybe science is just slacking behind again and we need some new tests before anyhting is conclusive.
As for saying "X amount of people that are not insulin resistant....." I don't think any of us know how many people are. Over half of americans are obese (wasn't that the latest bit of "fat people" news?) so that makes me think its more people than you think.
