Fat experiences

Anyone knows how is different acquired fatness from lifelong fatness? I mean if you were slim all your life and gotten fat like at 18, vs having been fat all your life, is there a difference between the shapes?

I imagine being fat your whole life, you are just used to it. Im open to learning if Im wrong though! As someone who used to be skinny and ate family sized meals to balloon up to over 300lbs, its an adjustment. Increasing appetite, struggling to get up, my belly getting in the way of things, and getting winded after a decent walk.

For me, it’s been quite the liberating release the past several years. I was quite the bony kid growing up. Could see my ribs until I was about 35. Having a belly and fat rolls gives me a kind of confidence in my physical presence I didn’t have when I was skinny. Same for my wife, who gained a bunch after her first pregnancy and grew into a lovely full-figured fatty 👍❤️

I've been fat or the very least chubby my entire life and its definitely something I'm relatively used to but I feel like it'd be hard for me to differenciate the two as I've never been on the other end of the spectrum

Thank you for your responses and experiences.
I wanted to know if you think theres a way to distinguish between a person who has been fat since childhood over a person who acquired obesity (☺️) after adolescency just with seeing their bodies

I have been at least chubby all my life. However, I got properly fat as a teen and young adult and then gained to become really obese in middle age. I definitly feel different now at my highest weight of 500 lbs. than when I was 300 lbs. 20 years ago. My appetite has noticeably gone up while my mobility has very much decreased.
