I'm debating whether I should aim to eat paleo 100% of the time or allow
occasional non-paleo eating (such as a non-paleo meal every few days as in
Cordain's book or a few bites of the family pizza or ice cream each day).
I'm wondering what arguments are for and against strict adherence, and what
other people's opinions are?

I'm thinking that occasional non-paleo would be a more sustainable diet
(feels less restrictive), however the longer I eat paleo, the fewer cravings
I get.  Any thoughts?

Thanks much!
