Those are some big claims in that title.

And how could they be true when we have statements like:

“BCAAs stimulate the building of protein in muscle and possibly reduce muscle breakdown.”

“Valine is needed for your muscle fibers to fire, for tissue repair, and for the maintenance of proper nitrogen balance in the body.”

“Leucine stimulates muscle protein synthesis and may be the dominant fuel involved in anabolic (tissue building) reactions.”

Well, unfortunately, the claims in the title of this article are true.

They come from research studies done on BCAAs, while the above quoted statements come from marketers.

BCAAs, or Branched Chain Amino Acids, taken on their own regularly and over time, can have a significant effect on body fat creation, muscle gain reduction, kidney trouble, type 2 diabetes, metabolic syndrome, and obesity.

And it's becoming quite a problem. Just google "BCAAs side effects" or "BCAAs and Type 2 Diabetes" and you'll find much more than you wanted to.

But how can they say these things and how does this all work?

Let's dig in and see.
