If you want an example of someone doing RVAF for the long-term, then Iguana , who is still following the forum, is the person to check. Given that RVAF diets really got majorly (re-)started with Aajonus' books in the late 1990s, almost all other RVAFers are much newer.
Palaeophil was an enthusiastic poster, but, to be frank, like Nicola and a few others, he was not a genuine RVAFer. He was a dietary orthorexic,a neurotic, someone who is always looking for the "perfect diet" and who is never satisfied with whatever diet he is trying out - so that he, like Nicola, would regularly invent negative symptoms in order to justify moving to some other dietary paradigm. He was actually quite a clever character, and wrote some interesting stuff.
There is something quite normal about members disappearing. It has nothing to do with changing diets. A lot of it has to do with changing online circumstances, such as Internet forums dying out due to the smartphone/facebook etc.But the real reason is that most people get tired of defining themselves by their diet. Most turned to RVAF diets out of purely selfish reasons, they wanted to get healthy. Once their health was achieved, and all their questions were answered, there would have been little point in obsessing further about diet, and they could then move on to other things, while still sticking to a RVAF diet. In other words, from being a "RVAFer", they become just some guy/gal who happens to eat raw meat.That's just normal. The long-termers who stay here usually have other motives. I, for example, had a miserable number of decades of ill-health, with people blaming me for being lazy(i had chronic fatigue at the time)etc. etc., and my reasons for staying on this forum are mainly to help avoid others from experiencing the awful pain and misery I had to suffer for so long - and, also, over the years, I have found that many knowledgeable RVAFers on this forum, however short- or long-term, had discovered things on their own which helped either to improve my road to health-recovery or expanded my knowledge in other areas.
