Protein...?

As we should know by now , the main amino acid which controls protein sythesis in skeletal muscle is leucine....

Well for those that didn't know
Leucine stimulates mTOR and muscle protein synthesis in both animal and human

The main things one need to build muscle from a workout are insulin, igf-1 and leucine.
The other amino acids are going to be oxidized or metabolized in the liver as the document explains.
So saying one should eat X amount of protein per day is simply incorrect. I would use a good bcaa + carb drink pre / intra / post workout
And follow healthy dietary recommendations after which.

Protein: how much and how often?
Layne Norton, BS Biochemistry, PhD candidate
Published:
January 2009


To find the optimal level of protein intake at a meal we must determine what the
optimal level of protein at a meal for stimulating muscle protein synthesis is. It appears
that maximizing skeletal muscle protein synthesis requires
approximately
~15g of
essential
amino acids
1,
2
.
It has been postulated that the amino acid leucine is responsible for the
stimulatory effect of dietary protein on protein synthesis
3
and 15g of essential amino acids
would contain 3.2g of leucine.
Thus
,
in order to determine how much protein from a specific
source is required to elicit the maximal response it may be useful to
also calculate howv much leucine is contained in the source.
One could then determine how much of the source
must be consumed in order to reach the leucine threshold. For example,
whey protein is
approximately 12% leucine
;
therefore
,
about 27g of
whey
protein would need to be
consumed to reach the threshold for maximal anabolism, whereas a source like chicken,
which has a protein content of about 7.5% leucine would require 43g of p
rotein to reach the
leucine threshold required for maximal stimulation
(Table 1
.
).
So it appears that the
maximum benefit level for protein at a meal varies dependi
ng upon the source of protein.
It
is important to note that most of these studies were done
on individuals who weighed
approxi
mately 155
-
165 lbs on average.
So if you weigh less than this you might want to
aim for the lower end of the threshold
;
whereas
,
if you weigh more you may want to aim for
the higher end of the threshold.

Theres so many to choose from its so difficult to decide, is there any brand everyone has a common ground on agreeing is good and effective? Obviously everyone has there preference. I'll need to invest in some casein also..my goal is to lean up stay the same size but cut in a lot, i do a lot of cardio so the cutting part wont be hard its finding the balance and not burning muscle which is tricky for me although i do lift as well, i want to get back to my strength (maybe not as strong as before) without getting too big
 
IMO and I think some one will agree with me if you are getting into taking protein do yourself and your wallet a favor pick a protein you heard the most about and seem to like/trust... everyone hear basically gave you there protein of choice lol as a newb it can be overwhelming but stick to the basics whey protein, isolate or concentrate just get one don't worry about casein for now (eat cottage cheese before bed almost all casein protein) as I have said before my list is price=100% ON whey.... Taste and mix ability= syntha 6..., the choice is yours bud
 
Thanks mate, i think when the time to buy some more comes im gonna have to try out ON 100% it also had loads of positive reviews on the site i checked so all those people cant be wrong..right?

You do understand that cottage cheese is LOADED with sodium so eating it before bed is not exactly what i would recommending to people
 
Then don't eat it.. I was just stating if you want to get casein before bed I think casein is over rated especially a newb, he just got the idea of spending 50$ on whey protein now people want him to spend another 30-50$ I know I wouldn't of done that when I started back in the day... Also they make low sodium cottage cheese just taste even more awful
