You would probably be severely deficent in all the other essential aminos. They're essential for life, lol. Not also to mention the all or nothing principle when it comes to muscle. All amino acids need to be present for muscle protein synthesis to occur (even though some are used more favorably than others). Doesn't seem like a healthy idea to me.
No offense, but wow. Yes you would lose muscle. First of all bcaas are not protein they are amino acids, three of the essential amino acids. You need to have all essential amino acids present to synthesize proteins, intake of non-essential amino acids is not absolutely necessary as the body can synthesize them itself. If you were to only consume bcaas they would be converted into pyruvic acid then changed to keto acid intermediates like CoA and fed into the krebs cycle, which produces ATP.
Amino acids can also be changed into glucose. To repair damaged tissue your body would have to remove the amino acids necessary from existing tissue (especially muscle), to build proteins more important in sustaining life.
This board is full of morons. How do you have ~2x as many posts as I and have not figured that out yet?
My advice: kick back and have fun with it.
Sooner or later people will either wake up, stop over thinking things, and start making progress again, OR they'll keep on going down the road they're on until they end up with a severe eating disorder. either way it's win-win for me!
Interesting to think about, but I'm not sure how effective this would be. There are still essential amino acids you wouldn't really be getting through your diet. I've never heard much about this type of massive bcaa loading. Try it and let us know!
Why tell him to try it? Essential amino acids are essential to LIVE and can only be provided by our diets. He would be putting his health on the line by neglecting them. There would be an endless list of health complications he could encounter if he had tried said protocol, not to mention possible death. Its honestly a really bad idea, really stupid. I replied "nicely" in my first post, but I can't believe someone would recommend trying it.
that's kinda why i pointed out the fact that there are essential aminos you wouldn't be getting. try it and let us know wasn't meant to seriously give this a go. but if he did, i'd want to know about it
