I asked one of the nephrologists (kidney docs) who works at the University of Pittsburgh about large amounts of protein being harmful to the kidneys. His reply was that there was no evidence that “too much” protein was harmful to healthy people. He said that the main reason that he restricts protein in patients with established kidney problems is not because it is harmful for their kidneys, but because if they eat large amounts of protein they accumulate larger amounts of protein breakdown products which is uncomfortable for them (since they cannot excrete them as effectively).[/quote]
Scott’s absolutely right, and that would not be the only inconvenient one would encounter. Even heathly bodybuilders could get drawbacks from prolonged protein overconsumption.
High protein diets causes accumulation of toxic metabolites like ammonia, causing you among other things to sweat with a stronger smell (in other words, you and your workout clothes will most likely stink).
High protein diets are also extremely dehydrating and, according to some researchers, can lead you in the long term (not that long) to become exceedingly efficient at breakingdown proteins by generating by default a more suitable ammount of protein-metaolism enzymes than what one normally has.
In turn, your excess consumption, eventually becomes your actually daily requirement because you’ll just need that huge amount of protein in order not to fall into muscle catabolism.
On the other hand, it has been demonstrated(Fu** I hate using this word) in quite a few studies that short term excess portein consumption leads to greater muscle growth. I suggest you look up articles from Torbjorn Akerfeldt about protein consumption cycling…he’s got a very interesting theory about how to benefit short term high protein diets without the long term possibly negative effects…
