I don't think it ever gets "easy." There will always be people in social settings trying to feed you food you don't want to eat. There is no getting around it. What gets easier, in my opinion, is that with time you get better at A. Saying no when you really don't want something and B. Accepting some of the things people give you as 80/20 without worrying too much about them. It is always important to not stress yourself out about it, which in my mind diminishes a lot of the benefit of eating this way.
