Protein deprivation and muscle building

[bettlejuice]

I was wondering of anyone had any experience with protein deprivation and loading?
I have a friend that swears by it.One day per week he cuts out all protein.He says that the following day he loads up protein again and his muscles literally soak it up.

and a lot of people swear by HIT.

Actually there is some truth to this. In the latest Rennie review he mentions that there is a saturation point, IE muscle can not soak up anymore, so one way to restimulate MPS is to reduce protein intake so that it can be "soaked up" again.

Quote[/b] ]Studies of the latency and duration of the effect of amino acids on MPS suggest that it takes 30 min for a stimulatory effect to be detected; thereafter the rate of
increase is rapid, and peak rates are obtained within 60 to 90 min (101). Then MPS falls back to basal levels despite the continued abundant availability of amino acids, suggesting that the system is full of protein and is no longer responsive to nutritional stimulation.

It is apparently similar to Carb loading that athletes do before competing.
Also interestingly what occurs is that due to the reduced protein intake the body actually "holds on" to the protein already within muscles as a defence mechanism.
This may go back to our very early ancestors when they sometimes went for days at a time without any protein source.When they finally consumed protein their bodies absorbed it and literally locked it in.
BoSox not sure about the scepticism,afterall if you haven't tried it how do you know it doesn't work?

I don't know if it resembles the carb loading process or about the body holding on to protein, the body actually uses what it needs and expels the rest. If you have anything concrete on this I would love to see it.

Here's another excerpt from that review that seems appropriate.

Quote[/b] ]Second, there is the problem of the habitual dietary intake of athletes who are subjected to much marketing and coaching information suggesting that they need to eat large amounts of protein in order to maintain or build muscle mass; this is a problem because habitually high rates of dietary protein intake lead to the induction of amino acid catabolic enzymes (particularly of the branched chain and aromatic amino acids) that decrease the deposition of dietary protein (162, 163). Until this effect abates (after reducing protein intake), there will be a tendency to exhibit negative nitrogen balance, so studies should not be conducted with rapid variation in dietary protein contents.

Sounds like somebody spent some cash on the Optimum Anabolics program (www.grow-muscle-now.com)...that's the "big secret" behind that program, protein cycling. You drop protein to 30g a day consumed just post workout, and you do this for 3 weeks, then you consume tons of protein for 3 weeks. The workouts do look somewhat interesting though.
