Layne Norton’s presentation from the International Society for Sports frequency to support maximal protein synthesis and muscle mass. Layne Norton, PhD. October 31, Watch The Video – So how does leucine stimulate skeletal muscle protein synthesis? Well first we need to. Layne norton suggest that to reach the leucine threshold one should will maximally stimulate muscle protein synthesis and that should work.

However, the real question is does eating more provide metabolic benefits?
That has yet to be seen. The problem with both of these is they do not account for recycling of the amino acids within various tissues, nor do they take into account that tissues like the gut turnover very rapidly and so much of the whole body flux of amino acids is from the gut.
Skeletal muscle morton over comparatively slowly and thus has much smaller effects on whole body amino acid fluxes. In proyein to get good information you have to look at fractional rates of synthesis and degradation within the skeletal muscle which 1 is much more difficult proteon more expensive 3 requires more skill and 4 requires a biopsy.
Thus it is often not used in studies. In our lab we are measure fractional synthesis rates. Two main questions we are looking at is 1 how much protein at a meal does it take to maximize protein synthesis?
This will likely be the crux of my PhD thesis. Layne, what is your take on omitting protein shakes and synthesix from daily consumption? True enough, most all powders are pre-disgested, manufactured dietary supplements, but I think the value of them cannot be denied. I think the biggest thing for me is wanting to include them for noorton two reasons: I eat eight times a day. At the suggestion of someone else, I cut out protein supplements at least for this first month to see how my body takes to itand am looking entirely to whole foods to get my protein intake.
The problem with that is that eating eight dynthesis food meals a day is musc,e really agreeing with my stomach, especially considering that I now have to eat more calorie dense meals.
So, for me, it is a big help convenience-wise, because I noryon time everything much better, AND get my protein requirement. And for the record, I have set my protein ratio at 2g of protein per 1 lb. My shakes normally ran 70g protein.
While I understand the importance of covering all bases by using whole food to make the best of varying amino acid profiles, do protein shakes certain products, anyway… my regulars were these type not have specifically engineered profiles that cannot be had through regular food, hence the importance of having them in the first place? I ask you because you are a highly regarded natural here on MD.

Musclee apologies for being long on words with my questioning, but that is just how I am. I think your protein intake is too high.
I have literally spent the last 8 years of my life studying protein llayne more recently my studies at the graduate school level have been spent studying protein synthesis and metabolism in depth. I would mitigate your intake to 1. Another example is vitamins. More is not better, better is better.
As far as having profiles that are better than whole foods, whey has probably the best profile in terms of bioavailability and leucine content and there is strong evidence that leucine is the only amino acid that can independently stimulate protein synthesis. I find that all protein products are pretty much useless as it is simple to get adequate amounts in a caloric threshold. Most people overconsume protein for no apparent reason other than paranoia.
I agree that most do over consume protein out of paranoia but protein proteij can be useful for convenience if nothing else, or if someone is a vegetarian, or has certain food allergies that may prevent them from getting protein from typical sources.
I guess what I am asking is some people believe more is better for protein but with leucine and other bcaas you get more protein intake as opposed to taking in a huge amount of protein in hopes that the level uptake is the same. Damn I confused my self. Does microwaving your meats degrade the protein? Cool thanks i just read a couple studies about it and wanted to get your opinion. But you are saying its not really a big deal anyways? It is absolutely no deal whatsoever.
You see proteins are long chains of amino acids that are linked together by peptide bonds. Heat and acid will both denature proteins which means they will unfold from this conformational state. The amino acids remain intact and are still available. Just to make my point that it does not matter if you denature a protein, look at what happens during digestion. Proteins are exposed to concentrated acid in the stomach 6 Molar Hydrochloric Acid which will denature almost ANY protein.
In the small intestine the denatured protein is then cleaved into individual amino acids, di, and tri-peptides. I have been adding Whey protein to my Oatmeal in the morning and I heat it up in the Microwave for about a minute. I was wondering if microwaving the Whey might cause it to breakdown? I believe I have answered this in depth before in this thread you might try searching for it for a more in depth reply.
Ive been doin no carb and im getting sick of the same foods! This is if using it on an empty stomach since its the fast uptake that probably is responsible for that effect.

Is it the same with BCAA: Can they be taken together with food or will that slow down and diminish the effect? In fact there was a study done looking at BCAA alone vs. Is it for the water content and its relation to how much your testosterone can go down when having too much water before bed? Is there a problem if I eat my regular 12 egg whites before bed besides bad taste?
Soy protein, any myths, truth or hidden dangers with it….? When someone has been in the sport supplement business as long as I have…well…I have the up most respect for Layne and Bodyfx2 and to debunk the myths of Soy seem needed! Soy has a bad rap. But this only happenes when soy consumed in huge amounts. Most studies on Human subjects show that this is false. So it is not as evil as most say it is. Small amount are helpful for males if taken. I am sure Layne can expand further as he is the man no pun intended.
They found no statistical difference; but muscpe were way better than wheat. Soy is actually pretty high in leucine Am J Clin Nutr. Consumption of fluid skim milk promotes greater muscle protein accretion after resistance exercise than does consumption of syhthesis isonitrogenous and isoenergetic soy-protein beverage. The first one certainly is interesting. I consider 2 scoops of soy as a pretty high dose. I believe most bodybuilders get residual soy through protein bars, meal replacements, etc where the concentration is pretty low.
At that concentration I eynthesis it is a problem. Is it because the body utilizes primarily BCAA during exercise? Because whey is in long peptides.
So the peptides digest slower yet assimilate faster?
Leucine: The Anabolic Trigger!
Just a curious question. Do you calculate the amount of protein coming from your carb sources along with your protein as your total protein count for the day. Does that sound right? I was wondering how well your body uses red meat, I know chicken is more Bio — available, but I cant stand it. My butcher sells the steroid-hormone free beef.
I eat 1 to 2 pounds of lean ground beef a day it seems to be working great. I was just wondering is my body actually able to use the protein effectively. I think they are both about the same. Layne your opinions if any at all on this new protein source for bodybuilders, gemma protein.
I did some checking and no its about the same. This is in terms of absorption rates. DO I nortkn it right? Its also plant ;rotein so I assume it also has isoflavones? I eat pre-workout meal a hour and a half before workout should i take whey with oats here too? I think whey post workout is prtein, but really i just use it whenever i need to get some extra quick protein in.
Do you believe there is an upper limit to how much muscle mass, naturally, a body can accrue? Meaning when you first start lifting you grow very fast for a period of time, then it slows, then the gains get slower and slower and slower. Is there really any benefit to using Whey hydrolysate.
I hear hydrolysates talked about so much but is it overhype? I also sybthesis protein shakes if i need to up my protein intake, as I find them a quick way to get protein in. What people forget to remember is that, all these supplements are good, but nothing beats good old nutrition which comes your food, chicken breast, eggs, fish, beef etc….
I like to mix whey powder with my oatmeal and wondered if the heat has a negative effect. Layne, What is the story with musvle fraction protein, ie: Is it a viable protein source?
Leucine: The Anabolic Trigger!
What are your thoughts and opinions. Research seems to suggest is may be a good alternative for casein. My understanding is that a protein was a BCAA. Can you clarify the differences for me? What makes one better than the other in certain time frames?
