Protein shakes bad for you..has anyone looked at this new research?

Hi all,

This article has me wondering if this research is legit or not. They are saying that BACCs compete with tryptophan which in turns leads to lower seratonin levels which can lead to obesity (due to lower satiety).

It appears as though they are talking about muscle building Protein Shakes in particular. They can contain BCAA's but I don't believe whey Protein generally does.
