Obesity, exercise training, and BCAA supplementation: All that glitters (may not be) gold
TLDR: BCAAs supplements may harm insulin sensitivity in obese people making problems with type 2 diabetes worse.
Supplement companies would have you believe their supplements are the answer to everything, and BCAAs saturate the market but this study shows that they may have differing effects depending on body composition.
It is interesting that they may undermine insulin sensitivity in obese people. The drawback of this study is that it was done using mice however they would not ethically be able to do this sort of experiment on humans generally.
