My biggest complaint is the references made several times to his web page that is not working. The URL is for downloading documents needed to work through the process discussed in the book but the page is not available. They should at least post a redirect saying why it has been removed and where the documents may be found. You can however join their Health Club for a membership fee.
I am intrigued with the concept offered but can find no collaborating evidence to back the claims and no specific published research is provided [perhaps it is available on the missing link].
