It's hard, b/c if you say you do poorly with grains, they find you some gluten-free brownies, and then you either feel bad b/c you have to explain why you can't eat them, or you feel bad b/c you ate them.
If there's any way for me to bring something to complement the meal, I'll do it, and try to make sure I can find enough meat and veggies, going easy on anything else. If not, I'll eat sufficient protein before I go (or maybe even a full meal), push things around and eat some bites while there, and just enjoy focusing on the social occasion. If it's someone who I think is open to hearing what I'm doing, I might explain it if asked; otherwise I'll just try to make what I'm doing completely non-obvious so I won't have to get into the details with anyone.
Hardest is staying a while with others. It's just hard for folks to wrap their brains around "no grains, no sugar," so I just say I'm doing low-carb and avoiding processed foods (so I don't get offered "low-carb" pasta! although that's no guarantee, sadly).
