Hmmmmm..... Have you read any of Dr. Erhets books? I don't think the Barefoot forum has ever really talked about metabolisim in lenght, but he refuts it. Even before I read his stuff I had a hard time understanding just how it would work, very "non-sensical" in my opinion. Look, eating is just FUN. It is, and it's a drug, PERIOD!! I have to laugh (and cry inside) every time I hear someone who hasn't eaten for 5 hours start talking about feelng weak, or light headed, or being irritable, and I think, "Druggie". LOL.
