I have a suspicion that they may be eating too much protein it is possible to overwhelm your livers capacity to do the urea cycle and to turn nitrogen into urea which is our water soluble form of nitrogen from amino acids I talked about this in my ancestral health symposium talk and in the debate I did with Ted Nieman which is now on my youtube channel and was originally on Chris Belle's under better stronger faster podcast but the idea there is that all of our livers have an intrinsic capacity which is genetically determined to convert the nitrogen containing amino acids in our diets into urea and if we exceed that it can spill over into ammonia which is not a good thing perhaps in some people who are eating lots of protein the alt may go up as they're up regulating sort of the processing of amino acids in an adjustment phase
