I don't like using the word paleo either. No one around here has ever heard of it so it doesn't really explain anything. Also, I am a Christian so saying I eat a diet based on evolutionary biology doesn't work too well. haha (and no, I don't want to argue theology here please)

Usually I say I eat "low carb/high fat" or that I "eat a traditional diet, we avoid grains, sugar and processed junk". Them sometimes I ask them if they have ever heard of Weston A Price, that dentist from the 30's? and I always direct them to Marks Daily Apple. :)
