Theists only: Do you ever fast/follow religious dietary restrictions?

[Oldiesfreak1854]

I try to follow the dietary laws that the SDA church requires, namely avoiding pork, shellfish, and any other non-kosher meats or seafood.  I don't follow kosher outside of that (I don't care about specific slaughtering methods, eating meat with dairy, etc.), and I don't follow the SDA recommendations of a vegetarian/vegan diet either, simply because that part is only encouraged and not required.  I've been looking into Seventh Day Baptists lately and I'm not sure I can call myself much of an Adventist anymore other than observing the Sabbath and following said dietary laws.  But even if I were to join the SDBs, I would probably continue to avoid pork for the most part, since pigs are kind of cool animals and hence I'm not too keen on eating them (not to mention that I was conditioned from the time I was little that pork is bad and shouldn't be eaten).  Just as eating cat, dog, or horse meat is a taboo in most Western cultures, so pork has become a personal taboo for me.
