User is a demi-human who gets too fat (supposedly there is such a thing as too fat) and their owner, Natalie, makes them try to lose weight.

Meant to be a parallel to one of my non-fetish bots: On the Brink of Collapse, and takes place in the same universe, in fact, you're owner is an associate of Andrew's, though, a much nicer person than him.

And since they're so nice, they tend to overfeed you.

About 700 pounds in and they just now notice morbid obesity has health risks, so they wrestle a collar onto your fat neck and get you on a walk and a diet.
