!!Thin Characters

* Brittany from ''Literature/DimensionHeroes'' has been stated to fit into this trope, though it has yet to be seen.
* Anyone with paranormal powers from ''Literature/ShadowUnit''. Merely ''having'' paranormal powers doubles a person's calorie requirements, and actually using those powers burns even more calories.
* Tennyo, at [[SuperheroSchool Whateley Academy]] in the ''Literature/WhateleyUniverse''. It turns out her mom is a superhero with Energizer powers, and can almost out-eat Tennyo. The ''one'' time Tennyo's felt full is after consuming [[spoiler:a horde of demons]]. It's possible her BigEater habits are an effort to try and make up in quantity for some nutrient that Earth food lacks.
** Exemplars and, as mentioned, Energizer type metas are also prone to huge appetites.
* The players of ''[[http://community.livejournal.com/jla_watchtower JLA Watchtower]]'' one time got into a debate of "Which team would win an eating contest? Wally West and Jesse Quick or Gar Logan and Aurora Andersen?" Aurora is about 5'2" and small-built, but is also an animal-shifter like Gar is. Her metabolism resembles a shrew's, especially if she's been working her shapeshifting a lot. Good thing she's also the TeamChef for the Titans.
* This ''[[http://dogs.icanhascheezburger.com/2008/05/14/funny-dog-pictures-toast-with-jam-please/ Lolcats]]'' page.
* Like Creator/DougWalker in the RealLife example down below, WebVideo/TheNostalgiaCritic seems to live off booze, cereal and junk food but never gets spots or looks fat.
* The guys from ''WebVideo/EpicMealTime'', who routinely prepare massive dishes with five- (sometimes six-) figure calorie counts and then eat them on camera. What probably helps their frames is that Harley is rather tall and Muscles Glasses (a personal trainer in real life) is often hitting the gym.
* Ian and Anthony of ''Smosh'' both qualify, although Ian seems to be the bigger eater.
* In ''Roleplay/SurvivalOfTheFittest'', Reika Ishida is shown to be one of these in pre-game, judging by the fact that when she orders something from A&W she gets a large hamburger meal alongside some chicken all for herself, and ''then'' snags some of the KFC bucket her sister and a friend are sharing. Note that this is a 4'9 tall and 95 pound teenage girl. Jay Holland also shows tendencies of this when he orders six [=McDoubles=] that have fries ''inside'' them, small cups normally used for condiments to be filled with Oreo [=McFlurry=], four more burgers stacked together, a bunch of milkshakes, a large Pepsi, and coffee at a [=McDonalds=]. Though, he does use the justification that [[spoiler: he just survived a terrorist attack, so he has the right to get fat]].
* The ''Wiki/SCPFoundation'' has, among its specimens, [[http://scp-wiki.wikidot.com/scp-913 SCP-913]] AKA "Mr. Hungry", an apparently ordinary African-American man who requires "the recommended daily caloric intake for a normal human ''every 2 hours''", otherwise he falls into a trance in which he will [[ExtremeOmnivore eat any solid matter he can]] in order to sate his appetite.
* In ''Literature/{{Curveball}}'', whenever [[SuperSpeed Red Shift]] goes all out, his powers also accelerate his metabolism for the next few days, with a corresponding increase in appetite. In addition, if he's going to be traveling a long distance at high speed, he has to wear a special IV harness that pumps glucose and nutrients directly into his bloodstream (and he's still hungry afterwards).
* LetsPlay/{{Strippin}} jokingly refers to himself as a food disposal unit, and the premise of [[https://www.youtube.com/watch?v=SRhnGOA4Amc&channel=TheStrippin one of his challenge videos]] is to face off against Smiffy from LetsPlay/HatFilms in a burger eating contest, with the forfeit being that the loser is slapped with a half-eaten burger. [[spoiler:Smiffy wins]]. It is worth nothing that Strippin gets away with this since he is very well-built and does lots of exercise to counteract this.
** Since moving to LA in early 2014, [[https://www.youtube.com/watch?v=G_URAbY3IKE&feature=youtu.be this has started to catch up with him]].
* LetsPlay/{{Turpster}}, by reputation. Smiffy of LetsPlay/HatFilms says that Turps has bought an entire family bucket meal from KFC and eaten all of it, ''himself''. He and Turps have a gentleman's agreement that they will, at some point, do an eating challenge.

!!Fat Characters

* [[CloudCuckooLander Ronove]] in ''Roleplay/TheGamersAlliance'' eats a lot and always seem to stay hungry no matter how much he has eaten. His favourite foods are strawberry cakes and sand gnome legs.
* Terry Munford of Website/DeviantArt's script series, ''{{Chris}}''.
* The chefs from ''WebVideo/EpicMealTime''
* Menelaos from ''Literature/GreekNinja''. After having caused a row by insulting Japanese food in front of Daichi, later on he is gulping down ramen and enjoying it. When Dawson questions him on it, he replies: ''"I like it, just I need a lot to get full"'', as his main grievance was that the portions were too small.
* LetsPlay/SimonLane constantly jokes about this in LetsPlay/{{Yogscast}} real life videos, with a joke in "[[https://www.youtube.com/watch?v=hHmXtvbmE5g&channel=BlueXephos Kicky Kicky Flow]]" about his consumption of Jaffa Cakes.
* While [[Franchise/SuperMarioBros Mario]] isn't exactly fat, in ''WebVideo/TheSonicAmigos'' he eats all of his and Luigi's spaghetti offscreen. [[spoiler: Maybe.]]

!!Whole Species

* The entirety of the human race in ''Literature/TheJenkinsverse''. Humanity's dense bones and efficient muscles and organs mean that a human's dietary requirements are something like quadruple that of most other sapient, spacefaring species of comparable size. Humans abroad in the galaxy are forced to subsist on offensively bland and uninteresting emergency ration spheres in order to meet their basic nutritional needs, and usually at a rate which taxes the supplies of all but the largest ships and space stations.
