Anon--
According to latest poll, we actually get about 2X placebo from the NSD (>60%).  That should be all the statistical significance that anyone would ever require to at least give the diet an earnest trial (or otherwise become happy).  It is human nature to almost hope that the diet does not work, but to not follow through with it and then claim it did not work for you is a major disservice to others who may be suffering much more than yourself and could benefit from the regimen.
Ebringer's LSD 
has been published in at least two peer-reviewed journals, along with results.  And, he travelled to San Antonio to deliver a free of charge 2 day lecture on AS in general and the results of his many years clinical success with the diet, specifically.
If you do not read 
all the appropriate journals, you might not know these things (I did not), and if you select only links to non-supportive and out-dated references you will never become aware of his work.  Fortunately for many of us we had one of his patients early on, willing to promote Ebringer's methods.
