I asked on the the MD's at our hospital (a nephrologist specializing in dialysis no less) about rhabdo. He said exercise is certianly a viable stimulus and he said it is most frequently seen in new military recruits. People un accustomed to exercise volume/intensity, sleep deprived and bad diet? he also mentioned that a viral infection (influenza) can really make things worse.
I was thinking aobut your original post here and the Zone supplies adequate protein, but not so much that one is overwhelming the kidneys, loads of veggies are at least a possibility for the net alkalanizing action. the Zone may be therapeutic in ways we never thought of.
