Just Looking:
clinically obese
Everyone will experience it slightly differently, but that line is right around when I started feeling it in a real way. Before then just felt like stages of chubby, but something I could hide.
I also stopped seeing my feet standing up. Bending over to tie my shoes has an actual obstacle and leaves me a little winded, XL starting to cut into my underbelly, things like that. Sucking in my gut has been doing less and less for a little while, but now it's completely pointless, all can tell, and from that point on, they only will be able to more and more.
The first time that there's undeniably zero doubt you got fat, is very fun though.
