I want to talk for a moment about a common narrative trope, "Person falls out of their normal life into a depressed state and after a timeskip emerges from it a comically exaggerated fat person."
I assume you can sense my "HOWEVER"
This trope is basically always "this person got sad, and then doubled their physical size in a month."
They're used in a "the FAT PERSON isn't the REAL YOU; it's you being LAZY and SAD but you can FIX IT" way.
1.) Your body is perfectly malleable as long as you Work For It
2.) The only cause of being fat is being weak (either weak-willed or physically weak)
3.) Fat people are pitiable
4.) Weight loss = redemption
Obviously not a 1:1 cultural comparison, but there is a strong similarity in "We're using an exaggeration of your reality to play to a normative audience at your expense"
