From experience, 500lbs is the line of no return.
300lbs is undeniably fat - you're not chubby or thick or husky. You're fat. You either like it, or are ambivalent enough it doesn't scare you the way it would other people. You can still participate in society, mostly, but the world doesn't have to stop to accommodate you.
+400lbs is definitely eyebrow raising for society. It's being unable to clothes shop at even Walmart. Its forcing you to slow down, forcing you out of normal society because you simply do not fit. It's modifying your habits, changing to more sedentary hobbies. It's having to take up 2 seats on a packed flight, impacting a strangers life when they find that plane full. But instead of letting all that mortification spark change, no, something pleasurable coils in your belly and whispers "its not that bad yet"
Thats a level of obesity you're not ready for. Trust me, and I barely dipped my toe in that class of obesity.
Simple things that you've taken for granted, things that have remained as your athleticism dwindled, now suddenly seem like Olympian feats. Waddling through a store? Might as well call the ambulance to wait for your inevitable collapse. An incline? No, silly, might as well call it Everest. Standing at the stove to cook? Bold to not have a chair nearby. Clothes for fat people? Ha, you've sized out of specialty stores. Now you need custom clothes. Getting off the couch? Now you gotta plan how many times you can get up and so you make those one or two attempts count by stacking snacks around you.
Once you hit 500lbs, and you ignore that tiny quiet voice saying, "woah, hey, lets slow down" and instead listen to that roaring hunger in your belly...
Well, you'll be able to tell us what 600lbs brings soon enough.
