Applejack admires a pony with a 'Healthy Appetite'.
Fat.
It's what you've known your whole life.
Couldn't exactly help it, your appetite never seem to be sated and you weren't the most active. Resulting in a physique of a giant, walking butterball. A fleshy sphere with four legs, a tail, and head stuck on it. Everything about your visage was thick. Face, cheeks, legs, everything. Most obvious however was your staggering large belly. Like you carelessly swallowed a exercise ball. Never appeared to sag or get flabby, but staying perpetually full does that to oneself.
Still, socially you had a nice life. No pony gave you flak over it, and even encouraged it occasionally. Name's like "Bottomless Pit" or "Garbage Disposal" where titles you had pride in than shame.

Breathing reduced to heaving, deep breathes. Waddling came to a crawl. Even your stance widened with newly added girth to your cauldron-sized tummy. You'd be surprised if it didn't scrape the ground after this.
Ending with fear that you'll explode from one more bite, you slowly take leave. "Over doing it" was far from how you felt while in a sugary-addled stupor.
Fat. No, Fatter.
Fattest. This was possibly the fattest you've ever got.
What exemplified your notion next was how your overly packed, taut abdomen wedged you between the door frame. Stuck. You binged to the point you couldn't slip through a door. Sucking it in
Summoning whatever strength you could, you stick both front hooves either side of the outer frame and push. Little by little your grossly overburden belly gave way
