This, eating around others without eating things that are not on your plan, is something you ARE going to have to find a way to face. Soon. No, you don't have to do it by discussing how your diet has changed, you don't have to face it the way the rest of us did, but you ARE going to have to face it. You are going to have to figure out who is uncomfortable in the situation you describe; the other people, or you, and why.

I'm not suggesting you HAVE to tell anyone anything. You CAN find a solution that works for you. For instance, if you want to go the expensive route, when others want to eat out with you, you can bring them somewhere you can eat on-plan and offer to treat them, that way they're more inclined towards your suggestion of location. Or, make sure you know of several different places where you can eat on-plan, and talk one up for awhile until, the next time you and that friend go out, that one place seems the obvious suggestion.
