From experience it seems that just mentioning them in your profile is OK. What's frowned upon and can be blocked, is if you started to post requests or demands in the forum.

Maybe a moderator can give a more detailed answer, but the general tendency is that merely mentioning it is not a problem, advertising it aggressively is however a problem.

I know someone who was skinny throughout her high school and collage years, and only started to plump up afterwards, from about 120 lbs to 160 lbs, slowly, over several years, and she realized it only at about 150 lbs, because she kept experimenting with new clothing styles, she now had a job and could afford new clothes, and she also gained mostly on her hips and butt, especially initially... so it was a shocking realization for her that she did gain weight, and that it was more than just a couple of pounds.

For those who are in the extra big sizes, it can be common to have trouble finding chairs with arms which can contain you, or even passing through narrower doorways or fitting into booths.

For those who are big enough that your size requires you to plan around it, what were the very first limitations you encountered?

It's so rare to see someone from Eastern Europe who was fat, has gotten even fatter, likes it and wants to keep going. Indeed, as you said, feeder culture seems dead in this region.

Just weight alone wouldn't be all that useful, because there are differences in both height and build, which would make someone super-obese and someone else merely plump, at the same weight.

What your body can do and where it can or cannot fit, would be a better criteria.

So, I would say it's where one starts getting bigger than most things are designed for. Chairs, cars, seats, booths becoming too small to fit into comfortably (or at all). Certain body positions and movements starts becoming very difficult or impossible (tying shoelaces, walking up more than a single flight of stairs without having to stop, etc.). The threshold would be when going through narrow doorways, fitting inside small cars and behind restaurant booths is still possible, but only with great difficulties. Where every physical activity is still possible, even if only for very short periods of time. A size which starts seriously affecting what one can or cannot do, but still not as big to make most activities impossible.

No, what would really be horrible is if she died at such a young age! If she needs to drop a little weight to stay healthy, than that should matter more than the fantasies and expectation of (to her) random strangers.

Strangely, most of my hobbies are quite active, and so the ratio of fatties is much smaller there than in the average population. As a FA this makes me happen across much less fat people than I otherwise would.

This made me think about what kinds of hobbies or activities are there, where the ratio of overweight attendees is really high?

Would be fun to see others' personal experiences.

You missed that I mentioned that she's very short, so she has to pull the seat forward for her legs to reach the pedals comfortably.

I know a woman who is quite tubby but not really all that fat. But she is short, and her belly almost touches the steering wheel. She can't push her seat back because then her legs won't reach the pedals, so she has to keep the seat quite far in the front, making very little room for her belly.

Indeed! The word phobia means an intense uncontrollable fear or hatred, but people are diluting it too much these days, using it on anyone who shows a mild dislike, or polite criticism, or even just unwillingness to show open support.
