Granted this was in rats I believe, and both groups were put on a hyper caloric diet high in fat. The leucine was simply added to the drinking water.
I'll check out some more studies on this, but I'm actually wondering if BCAA's, at least leucine which seems to be the most powerful mTOR activator of the three BCAA's, will increase fat loss or increase LBM even when you do get enough BCAAs through whey supplementation. But I don't know.
But BCAAs are certainly smart to take in addition to whey protein. From other studies I've seen that adding leucine to a whey protein shake plus simple carbs increases protein synthesis more than the whey shake alone.
My thinking has been that when you ingest amino acids in free form you might obtain a different biological response than loading up on the same amino acids from protein. Thinking being that if you shot down 7g leucine your body and receptors (like mTOR), are getting a higher substrate for the receptor than it would by slowly releasing the same amino acids from protein.
Arginine and it's reaction with the NOS enzyme f.ex.
Do arginine rich food types have the same benefits or able to elicit as powerful a response? Some doctors report success in studies using high amounts of free arginine to treat a host of symptoms, like moderate hypertension.
Others have failed to replicate that result.
Ok, now I'm drifting off.
