Pretty much this.
'cause if you look at all these morbidly obese b*stards that are bed ridden. When they get to the point where they either can't walk or won't, they get BIGGER from there on out. I know with little to no exercise coupled with eating will produce weight gain, but these fukkers are STILL gorging after they sink into that mattress. People are STILL bringing them obscene portions of fukking food for reasons that make me go

.
When the big b*stard can't cook/purchase their own meals, the weight gain falls on the blasted caregiver which most of the time is either some woe be gotten spouse or some kid who grew up being ordered to just push troughs near 'em and wipe 'em down like we see in them pictures. I know it got eating disorders that fukk with some of these fukkers mental, but alot of the times it's just Caligula type gluttony being carried on by the person to get bedridden and then the family takes up the damned mantle.
