I agree, though I wonder about correlation vs. causation. In my view, it's not so much being 500+ that is the problem as the lifestyle that gets you that big.
I know there is disagreement on how much of being that size is nature vs eating/habits for BBWs, but there is no way anyone gets to be 500+ lbs eating healthy and exercising moderately. (I mean, just about any model who reaches that milestone brags about all the "work" they put in to reach it. I've never seen one say "omg, how did I get this big? I barely eat anything" and actually mean it.)
I would posit that the thing that really is a problem for the 500+ lb ssbbw is their sedentary lifestyle and the food they consume. Probably mostly the latter: I know you can be active and get to 500+, though most probably aren't super active as it takes a lot to haul 500+ around, But even if you are active, you have got to be eating a lot of fatty, sugary or salty foods to get that big. I see no way for someone eating just fruit and veggies and some lean meat to get that big. And it is the effect of eating those foods that cause the problems like diabetes and clogged arteries.
Regardless of the actual cause, you are right about life expectancy of people being shortened by extreme weight. And I know on another thread, someone said they have seen lots of older 400+ lb SSBBWs. To that I would first question as to whether it is true, but the question I doubt he would be able to answer would be how long they have been 400+ lbs, as I doubt someone who is 500+ lbs in their 20s, let alone their teens, and stays that weight their whole life is going to live as long as if they had maintained a much lower weight.
