Death by Gluttony

"If I eat one more piece of pie, I'll die!

If I can't have one more piece of pie, I'll die!

So since it's all decided I must die,

I might as well have one more piece of pie.

MMM -- OOOH -- MY!

Chomp -- Gulp -- 'Bye."

- -- Shel Silverstein, "Pie Problem"

Big Eater may be a common trope in fiction, but in real life even this behavior is not without immediate risks. Eating too much in one sitting can cause one's stomach to rupture, which has very unpleasant consequences. In real life chances of survival are 50-50, but in a fictional work it's usually portrayed as being lethal.

Sometimes in fiction, the person's body bursts, spilling out their stomach contents and entrails. This grossly exaggerated variation is usually Played for Laughs and by extension not always lethal.

Sometimes involves a Wafer Thin Mint. Compare Balloon Belly. May turn into a case of Death By Irony, particularly since the entire point of eating is to keep oneself alive.

 * In the novel The Natural, Roy has an insatiable appetite that finally comes back to bite him; after devouring 6 cheeseburgers for a midnight snack, his stomach finally gives out (it's unclear what exactly happened, but it doesn't seem like it actually ruptured). He was rushed to the hospital and ended up surviving, but it severely hurt the team's chances of winning the final game.
 * In "Monday begins on Saturday" by Brother Strugatski there is "A model of a Human unsatisfied by gluttony", which eats whatever it can reach (including two TONS of fish) until liferally exploding into pieces.

Live Action TV

 * 1000 Ways To Die has a bulimic model die this way in one episode.

Music
"Sambo had an uncle, an uncle very rich
 * This is one of the many deaths suffered by Sambo in the schoolyard song "More Work for the Undertaker":

Ten lemonades and ten ginger beers, and then he went off pop."

 * In Nethack, eating anything when satiated carries the risk of choking to death over your food. Choking on a fortune cookie makes a particularly humiliating YASD. Just for Pun, polymorphing into a metallivorous creature and gorging on too much gold makes the cause of death "eating too rich a meal."
 * Mr. Luggs from Luigis Mansion, he ate himself to death and continues to eat more even as a ghost.
 * Melvin Underbelly from Overlord. Not so much at first, but in the expansion, you find in trapped in an Ironic Hell where he's given food until he explodes and can't control himself to stop, only to be revived over and over again. Using Melvin as a walking time bomb is crucial to the puzzles in said abyss.
 * In the Atari 2600 game Mangia', one way to lose the game is to eat so much your stomach explodes. This is quite easy to do, what with your mother relentlessly serving more food to you.

 * Another one, however, has Homer in Hell, forced to eat all the donuts in the world as a sort of ironic punishment. Not only he eats them all, but he still wants more afterwards!
 * Futurama: This also happens to Bender in one of the Anthology of Interest episodes when Prof. Farnsworth makes him human, and one week later he finally eats himself to death.
 * A variation is also seen in one of the oldest Woody Woodpecker shorts, after he ingests a rather strong drink. Somehow it also propells him upwards like a rocket...

 * Happens in one episode of Slimer And The Real Ghostbusters, when two talking animal dogs eat a bunch of Slimer's dehydrated food pills.

 * For example, the snake that swallowed an alligator and exploded (or got ripped apart from the inside out).

 * Large dogs that scarf down huge meals, then roll over quickly during play, can cause their overloaded stomachs to twist too far, fatally obstructing blood flow to their digestive tracts.
 * Due to comparatively abundant, high calorie food that is cheap and readily available in most developed nations, health complications from gluttony is also comparatively common, but its a slow death that saps lifespan by inches for the most part. Stomach bursting episodes happen but are thankfully rare.
 * During the Siege Of Leningrad in WW 2, this was a real problem. Many undernourished people (especially children) died after being rescued, because they were allowed to eat too soon after evacuation; the technical term is "Refeeding Syndrome"
