I am a Christian, and evangelical one at that (meaning, I do believe that sharing my faith is an important part of practicing my faith) . . . I'm also a paleo evangelist. But in both cases I've learned that the best way to share what you believe in such a way that it is respectful and others actually want to hear about (rather than forcing it down their throats) is to just live like you believe it and share honestly when people ask you questions. If you share about real food with your friends and family and it catches on with a few of them, then they'll share it with their friends and family and on and on and hopefully, some day soon it'll reach the obese woman in her chair and she'll be at a place where she is prepared to hear the truth and she'll change her life for the better.
