There's some truth to your body being resistant to the woes of morbid obesity if you were huge at a young age. That tends to be more true than not - your body while it's developing learns to overcome those maladies normally associated with it and better prepares you more than if you grew up thin or average and blob out later. Hell, look no further than MochiiBabii - girl sprinted towards 400lbs and got Covid, then had to tap out for good. Meanwhile someone like BoBerry was over 500lbs when she was in high school, is over 600lbs now, and is ostensibly living a good life.
That being said, the engine of your proverbial car wears out faster if you're pushing it to an extreme like that. You could have high performance but you're not going to last nearly as many miles as someone taking it easier on themselves. BigCutie Summer came to mind - she was over 500lbs all of her adult life and the second she got sick and hospitalized it was over. Supersoft might have more years left in her but I'm betting she's not going to see the end of the decade even if she about-faces. Continuing and even pushing her limits? Much more likely she keeps over in under 2 years.
