In my opinion, I don't think there is ANYTHING that we can NEVER have again. In his Atkins for Life book, Dr. Atkins lists alot of those items that are "taboo" now, as things to have "in moderation" later in maintence. As in a life long program. Of course there are those items that may set you off on a wild binge you may need to avoid forever...just depends on your will power and what triggers you to over indulge.
