Since my question doesn't seem to be getting any replies where I first posted it, perhaps here it will.
"I'm really new to these forums but not new to lifting/dieting. However recently the suggested values of the RDA as well at further literature as well as constant debating with a close friend of mine has made be question just how much protein I should be ingesting. If the RDA recommends .4-.5 grams per kilo, for non-active and a max of .9 per kilo for highly active adults (body builders included) where did this idea of pushing the protein limit come from? I have found very little evidence or documented cases of people gaining much faster than one another with different protein intake levels. From my understanding the body can only properly digest 25-35 grams of protein per serving (which makes sense when you consider most high protein foods are just lower than that number.)
I do understand that there are some health benefits to having more protein in your system but it seems that there is a limit, not to mention of overload on the kidneys.
If someone could please provide me with links and such showing why/how as well as how much more effective consuming more protein is, it would be greatly appreciated.
I'm sure this has been discussed before but I am having trouble finding any straight answers that are well backed up with literature that supports such claims.
Edit: After a bit more searching, the closest artical stating such claims was this one Even there they say 1.6-2.0 grams per kilo."
