    I guess what I meant was more along the lines of:"The suggested starting point is" then to move up or down from there. I was just surprised at the caloric differences it would make to go from 1:1 to .5:1Again I am obviously a newbie here.

    These have nothing to do with calories.  It's just the ratio of protein to fat.  For instance a 1500 calorie diet with a 1:1 ratio would be 115 g of fat and 115 g of protein.  If you were to use the .5:1 ratio it would be 88 g of fat and 176 g of protein.

    It seems that 20 grams for a meal doesn't make much sense if you're trying to hit 1g/1lb of muscle. If a guy is 200 lbs, with 175lbs of lean muscle.. the guy would have to have 8 meals spread throughout the day.Personally.. I don't think it really matters how much protein you eat in any given meal.. as long as by the end of the day you hit your target protein intake.. But one factor would be the rate of protein absorption, so maybe consuming a fast acting protein like whey and no fat, you should have 20g.. and protein synthesis lasts for a hour.. whereas consuming a steak.. you could consume 60g of it.. and you'd have protein synthesis throughout the rest of your day.does this seem accurate?

    What would be our take on this article? The article is a bit long so I'll summarize the key points herehttp://www.bodybuilding.com/fun/satternorton.htmUnderstanding the difference of slow and fast acting proteinFor whey protein it takes 20-40 mins to reach high levels of amino acids in our blood stream, and high levels for protein synthesis; whereas casein takes 3-4 hours.Taking them together, casein will affects all proteins consumed, slowing any fast acting proteins into a slower acting protein.Consuming protein to maintain elevated levels of amino acids doesn't stimulate protein synthesis. Meaning, you can have high levels of amino acids, where as the rate of protein synthesis can slow down, which doesn't lead to muscle mass; the rest of the amino acids would just get pissed out.So the observation is, to stimulate protein synthesis, you drive the intake of amino acids really high and really fast (whey intake), but 3 hours later the rate of synthesis tapers off and return to normal no matter what you do with whey.% Used up vs % ConsumedWhenever we consume any amount of protein at any one time, 50% of that protein goes to muscle tissue, 20% is incorporated into other body proteins, and the remaining 30% is oxidized. Protein breakdown is natural and usually comes next when there is elevated of amino acids and protein has been fully synthesized.Diet scheduleTo maintain high levels of protein synthesis (advantage of whey) and lower protein breakdown (advantage of casein), timing should be more concerned with when you take fast acting protein vs slow acting proteins, and shouldn't be relevant to the time of our workout.Step1: Take whey protein after consuming our first meal of the day. Having a meal suppress muscle breakdown. If we consume carbs in our meals.. which drives up our insulin, there will be a great anabolic affect. After whey protein has been assimilated, amino acid levels will drop; but not by much because of the meal.Step2: After 2 to 3 hours, consume a meal with slow acting proteins (casein). We wait for the amino acids to drop down a bit in the blood stream to restimulate protein synthesis again.Step3: Alternate between step1 and step2 from meal to meal.Conclusion:The level of protein synthesis is DIRECTLY related to the rate of change between levels of amino acids. So if our levels of amino acids is low, and we consume a large amount of amino acids, protein synthesis takes affect. If our levels of amino acids is high and we consume a large amount of amino acids, protein synthesis will NOT take affect. So we have to continuously raise and drop levels of amino acids throughout the day.This does not contradict the link I posted about consuming .82g/1lb of muscle. Because it only measured rate of protein synthesis after a meal, and does not mention the levels of amino acids within the body prior to a meal and after a meal.

    i agree with the conclusion there and it is why you do not want to continuously flood your body with aminos as you are not doing anything to help build muscle and are actually doing just the opposite as you need that drop..

    I've done it before and I noticed no difference.  Probably better off not doing it because the stress it would cause would cause you to go insane.

    okay got myself a casein shake. I will follow the diet as prescibed in my last post of flipping between whey and casein throughout my day. Each scoop at 24g of protein.. so this would give me 75g right off the bat. Assuming I have my whey at lunch with my bulletproof coffee.. then 2 hours later.. have my casein shake. Then I'll do another whey scoop after my work out… and another scoop of casein before I go to bed. I will still be eating meat whereever possible though (replacing my powder supplements).. as long as I hit 150g of protein by the end of the day.
