Hello sirs, looking for something slightly niche: stories in which a character is fattened up by eating an otherwise normal amount of food which, due to magic, technology, an alien nature, or other reasons, has a much higher caloric/fattening ability than regular food.

A couple example include:
This story (warning: MALE):

And the description from this:

Gwen's flabby arms wobbled and shook with exertion, the overstressed webbing creaking loudly and ominously with each passing second. Smaller portions of the messy web fiber snapped and gave way, and with each inch Gwen managed to gain it felt like she lost a whole freakin' mile.

"C-come on...!" She hissed out, scrunching her eyes in frustration. Never before had getting up felt so hard, but then it'd only been recently that she landed in this strange dimension. With food so fattening that even a single slice of pizza or a single sandwich left her a dozen pounds heavier than when she sat down, it was basically impossible to curb her rapid and endless growth.

Unfortunately for the Ghost-Spider, that meant her body had no time at all to adapt. Despite her super-human strength, it seemed her muscles didn't take kindly to being so caked in lard, and as a result it felt like the very powers she held so dear to herself had been stripped from her in an instant.

As Gwen struggled only harder to right herself on the ground, she was met with the nerve-wracking sight of the dual webs giving up their last bit of chemically-woven chordage. With a resounding boom she cratered her flabby ass on the ground, and her progress was reset to zero.

"...This sucks."

Any similar pieces would be GREATLY appreciated.
