ok, i'll pick it up from the general topics board.
there was a post regarding houseguests on a restricted (low carb) diet and cooking for them. comments were made by a few, myself included, that indulging the guest's diet should be limited.
to expound on my views:
i believe in treating my guests well, but only to an extent. they get the good towels, i keep a nice guest room with good sheets, quality hangers in the closet, i stock my guest's preferred, if i know it, beverages, and so on. i also try to prepare meals/foods i know my guests will enjoy.
i draw the line, however, at accommodating people who are on very restrictive diets for lifestyle reasons. by that i mean that if someone is following atkins, south beach, or one of the myriad other fad diets out there for no other reason than to lose weight, i'm not going to be especially concerned about their restrictions. this is different from medically necessitated diets (for diabetes, diverticulitis, etc.).
i was raised to believe in being a good host, but i was also raised to believe in being a gracious guest. you treat the host's home and possessions as if they are better than your own. you tidy up after yourself (make the bed, hang the towels, etc.). and when served food, unless allergic or medically prevented from eating it, you take it thankfully and pretend to enjoy it even if you don't. you don't have to take a lot, and at family-style gatherings, you can skip some of the stuff you don't like. you do not, however, wrinkle your nose at something, or tell your host that you don't like something. when refusing something, a simple "no thank you" is sufficient. better yet, when it's nasty-ass canned fruit cocktail served for dessert, you say "no thanks, i couldn't possibly eat another bite after that wonderful meal."
as far as i'm concerned, if a guest is slavishly devoted to a fad diet, then it's up to that person to feed him/herself. i will attempt to meet their needs. in the instance of low-carb, i would make lean proteins, lightly-prepared fresh veggies and whole/complex grains. but if that's not good enough, i'm not going to worry about it.
guests should be able to adjust their wants enough to graciously accept what is generously and lovingly provided. it's only for a short period of time.
