I have a general policy of not explaining or promoting any way of eating to anyone. Not even my best friend has received the spiel about the wonders of happy eating. I'm through trying to inform, enlighten, and convert people to however I happen to be eating. I'm sure everyone around me is grateful. I used to be quite the evangelist.
I do think it's really freeing to be less self-conscious about what you eat. What a huge relief to realize that nobody cares. I used to think everybody in the room was watching me closely, and either impressed or disappointed with my choices. Delusional much? Even if someone does notice or comment, it's usually a casual observation and not a judgement. If someone does judge your food choices, realize that it says more about them than you. I try to remember that what other people think is none of my business.
Now that I've chilled out, I have no problem sitting down in front of people with a pint of ice cream and a spoon, or eating my chicken and strawberries at work when everyone else is having sheet cake. I eat whatever feels best and makes me happiest at the time. It's a massive relief to have "what I want" as the guiding factor and not "what they might think." If what you eat is influenced by what you imagine other people are thinking, it creates all kinds of weird fallout and delayed resentment.
