good story! I never was a major evangelist IRL, no...but if people offered food or asked about my wt loss, I'd say, "I quit eating sugar and white flour" and if they asked more, I'd talk about paleolithic nutrition theories, insulin, etc, until their eyes started to glaze over. But only if they asked for it.

I think it's natural to be really excited about any new idea that works for us at first, to want to share the good news, but then most of us calm down and realize shoving any concept down others' throats is not a great way to help.
