I'd say it probably is more common among gainers. It's an aspect of feedism we can get into that isn't inherently sexualized.

What BMI calculator was that?

Wait, have none of you all encountered death feedists before?
There's a small corner of feedism that enjoys the health issues and struggles of extreme obesity. They aren't super common, but they're out there. Generally they're feedees who are into their own deteriorating health.
Not something I'm into personally, but you see them around on some social media sites.

So the Band Size (the number) is the size around your ribs below the breast.

The Cup Size (the letter) is the difference between the fullest part of the breast and the band size. It varies a little by company and country, but generally A-1", B-2", C-3" and so on. Generally the variance is after D and is in how often they use double letters/ the whole alphabet.

Because it's the difference in sizes a larger band size makes even fairly large cup sizes less impressive looking. It's how some of us are rocking large cup sizes without looking huge.

I'd say most likely it's over 600 with healthy lungs. But if you've got lung issues already it's probably possible much sooner. Your weight would just compound the existing issues.

Depends on the day
Work days 3-5k
Day off, less than 1k if I can help it.

Pizza, as long as I'm not having to pay for it.

Depends, if I have to do one for some reason then pushup. If it's which would I like the ability to do then pull up. Always been fat and never able to do one, so it would be novel.

Five miles once a week, 2.5 miles gets me to local fast food, so I could make it a worthwhile walk.

Vanilla shakes, I'm not a big fan of chocolate ice cream so chocolate shakes aren't super tempting.

Free seat on the airplane, it would allow more travel. Also without the rides most theme parks are pretty dull.

Either? Honestly it depends on what the bottoms are for the pool. Shorts are fine for the pool, but if it's a speedo I'd be a touch more hesitant.

Strangers, don't have to worry about judgement that I'm going to have to hear about. Select friends, a few know I'm a gainer. Not family, they'd couch it as concern for my health but I'd get lectured on my dietary choices.

Pop those shirt buttons, exposed belly is less embarrassing than exposed underwear or butt.

Ice cream everyday, I've not run since highschool so I might not notice the loss of ability for a while.

Wow there's a lot of factors that effect this. Tried this with a scale on 3 different counters and got 3 different weights.
10 pounds from the lowest counter
27 pounds from one that made the scale even with the bottom of my belly
46 pounds from one I can actually plop my belly on.
Same spring scale on all 3, my digital scale is too wide to sit on 2 of the counters.

I'm sure you would have groups hanging around the same size people, but it would be interesting to see the people who attracted a group by accident. Like someone in the 400 to 500 range whose gluttony tends to inspire the same in others would be super popular. Someone who inspires fatness in others by being your goal. They're not trying, it's just them.

Definitely feeling fat today. When I got into my car this morning the wheel was rubbing against my belly. I could push my seat back a bit so everything was fine until lunch. I may have tripled my usual order and stuffed myself at the restaurant. On my way home I had to undo my belt and my belly was rubbing against the wheel again for the drive home.
