There is an ongoing gag about how much Liz Lemon loves to eat, especially junk food (perhaps because her life is so hectic she never has time for proper meals.) Liz also gets pretty violent when someone steals her food.
Jack also shows some stress-eating tendencies of his own, such as in the first season episode "The Baby Show", where Liz remarks to Josh that "Jack Donaghy is gonna kill me and then he’s gonna kill you and then he’s gonna fold us up in a pizza and eat us."
49 Days has the thin Ji Hyun's stomach constantly growling whenever anybody mentions food. She also never turns down an offer of dinner.
Mike Stivic from All in the Family, much to the irritation of Archie, whose fridge Mike is always raiding.
Fred of Angel is shown to eat a lot, despite being played by the waifishly thin Amy Acker. Lampshaded when, after breakfast with Gunn, he says "Where do you put it all in that little tiny body?"
The Flash (2014): Barry, due to being a speedster. In fact, it's a physiological necessity: He metabolizes food so fast that he'll collapse from hypoglycemia unless he consumes massive amounts of food at a time. Cisco Ramon at one point estimates that Barry would need to eat over six-hundred tacos daily to meet his food intake needs. In the crossover with Supergirl (2015), Barry states he needs to eat 10,000 calories.
Supergirl (2015): Kara Danvers also loves food and regularly consumes tons of it. Not being human, her body doesn't react the same way to it, and she stays thin and fit. This comes in handy, when Barry, who needs to consume tons of food to maintain his Super-Speed, wants to find a nice takeout place; Kara is happy to help. This annoys her human adoptive sister to no end.
Kara: Pass me that last potsticker. Alex: Uh, no. That one is mine. You've had four! Kara: If that potsticker is not in my mouth in two seconds, I will melt your face. Alex:[handing her the last potsticker] I hope you get fat. Kara:[chuckling] Not on this planet.
Best Friends Whenever: Despite having a slim build and impressive athletic prowess, Cyd often displays a love of food such as eating two lunches at once, always being hungry and eating halfway of chocolate from the garbage in "A Time To Rob and Slam".
On The Beverly Hillbillies, Jethro Bodine would eat any unguarded food (or what appeared to be food) in the kitchen. His typical breakfast was a large mixing bowl filled with Kellogg's corn flakes and milk.
D.I. Peter Carlisle in the BBC miniseries Blackpool is almost always eating, unless he's unhappy.
Agent James Aubrey from Bones. If a scene has him sitting down, it is almost guaranteed that he will be sitting in front of a spread of Styrofoam takeout containers (which he will invariably refuse to share with Booth). One episode had the team investigating the death of a TV food critic, and Aubrey acted like one of his heroes had been slain. He even had to resist eating week-old food out of the guy's van.
Upon being invited for dinner at the Summers home, Faith is ravenously shoveling food down her throat and sneaking food off of Buffy's plate. Slayers in general are big eaters, Faith was just the first one to demonstrate it onscreen. Apparently, Slaying makes them "Hungry and Horny". Given Faith's living situation, it's quite possible she hadn't eaten for a while.
Buffy is apparently more sneaky about it.
Giles: All I know is, the fate of the entire world may well depend on... (sees donut box) did you eat all the jellies? Buffy: ... Did you want a jelly? Giles: I always have jelly; I'm always the one who says "Let's have some jellies in the mix"! Willow: We're sorry... Buffy had three!
Brent and Lacey from Corner Gas. Brent even eats a bowl of pierogies in under 5 seconds and says it isn't his best time. He only took so long because Lacey fed him a big plate of chili cheese dogs before their eat-off in an attempt to fill him up.
Lindsay Messer on CSI: NY sometimes. In one episode, Danny asks if he can get her something to eat while she's processing evidence, and she asks for a whole list of stuff. Danny gets an Oh, Crap! look and she has to assure him she isn't pregnant again.
Jake Martin from Degrassi is introduced in the episode "LoveGame, where he scarfs down dinner quickly and is still hungry later. Possibly because he may have smoked earlier.
The Androgums in "The Two Doctors" had huge appetites and would eat just about anything, including their own species.
"The Christmas Invasion": Jackie's never-seen friend Howard, whose pajamas and dressing gown are loaned to the Doctor, apparently gets so hungry in his sleep that he keeps fruit in the pockets of said dressing gown.
"The End of Time": The Master has been revived, but he's... not quite right. One of many unsettling effects includes an intense, intense hunger. At a food stall, he orders everything they have in stock and devours it all at high speed. In another scene, he eats an entire roasted turkey within a minute.
Doom Patrol (2019) has Rita, who eats enough food for multiple people because being a Blob Monster (and effortfully focusing so that she does not revert into said blob) requires a lot of energy.
Jayne Cobb seems to spend more time eating or looking for food than another crew member of Firefly, more in the feature film.
"He's always eating! That's why they're so poor."
He has, on at least one occasion, called dibs on food abandoned by other crew members.
"Hey, free soup!"
At least part of it is because the average food for spacefarers is protein paste. As soon as any fresh food becomes available, even Inara becomes a Big Eater. Also, Jayne is massively muscular and is called upon not only to fight, but to move heavy objects and the like, and is constantly training, so he's losing/using a lot of energy.
In the pilot of CBS's The Flash (1990), Barry Allen, much like his nephew in the comics, was explained to burn calories at a tremendous rate and was thereafter shown constantly inhaling food. In one episode he's shown stopping a crime at a banquet, and when the people he saved look around after he speeds out, they notice the turkey (Not cold cuts, the entire bird) is gone. The next scene shows The Flash finishing off a drumstick.
Maris, normally mentioned as being so thin she can hide behind breadsticks and so self-concious about her weight she suffers a freak out if she gains a single pound, becomes this when she hits peak stress, just eating and eating and eating.
Daphne, briefly, during one arc (to cover the fact her actress was pregnant). She only acknowledges there's a problem when all three Crane men need to pick her up off the floor. Turns out it's because of subconcious feelings over her relationship with Niles. Once it's worked out, she's able to go back to her regular eating habits.
Joey Tribbiani from Friends. In "The One With The Rumor", he volunteers to eat a whole Thanksgiving turkey, which doesn't mean he'll stop eating until then (He calls it "warming up."). He eventually does eat the entire turkey, and still has room for dessert. "The One With Phoebe's Birthday Dinner" involving Phoebe's birthday dinner at a nice restaurant. Over the course of the episode, everyone, including Phoebe, leaves for other activities...except Joey. He's bummed at first but lights up when all of the already ordered entrees arrive.
Joey: Dinner for six for one? (to waiters) You guys are about to see something real special... (he even eats the birthday cake afterward) Joey: This is the best birthday ever!
In "The One Where Ross Got High", he even eats - and enjoys - Rachel's infamous Shepherd'sTrifle. He likes it so much that he sneaks around and eats the four uneaten portions that the others couldn't manage.
Joey: What's not to like? Custard? Good. Jam? Good. Meat? Good.
In the AU episode "The One That Could Have Been", everyone imagines what life would be like if Joey had married Monica, an excellent chef. Cue an imaginary scene where Monica is serving a table full of food to her now morbidly obese husband.
Steve from Full House, who is also captain of the wrestling team. Most of his scenes involve him eating or talking about food. One episode even shows him grabbing food from the Tanner residence before his dinner date because he wants to "warm up". This continues in Fuller House and he's still in perfectly good shape 20 years later.
Carly Corinthos Jax of General Hospital. Despite never being portrayed by an actress above a size four, Carly's love of junk — especially pizza and chips — is legendary. In 2009, junk food nearly becomes its own character when Carly's perilous pregnancy forces her to go on an all health-food diet. References are made on a near daily basis about how her husband and sons are keeping her from her beloved crap, and when Carly finally goes into premature labor, it's while on a clandestine trip to score an order of fries from her favorite bar.
A more modest though still unrealistic form of this ability is displayed by the waifish title characters of Gilmore Girls. Lampshaded when Luke comes over to Lorelai's house and looks in the refrigerator:
Luke: There's nothing in here but ice cream, candy bars, cookie dough, frosting — why are you not 450 pounds? Lorelai: I know. Scientists call it the Lorelai paradox.
In an early episode, Will takes a distressed Finn to an all-you-can-eat restaurant where they can talk. One shot shows their plates side-by-side: Will's contains a moderate, healthy amount of meat and salad/vegetables, while Finn's, which is the same size, is piled high and overflowing with everything you can think of. It continues to be implied in later episodes that Finn is a Big Eater: Brittany points out that "You have sloppy joes for lunch every day and think you can get away with it," and being ravenous between meals is the reason he ends up dedicating a week of his life to a Grilled Cheesus. Which he eventually eats. When it is at least a week old and has traveled back and forth between home and school, unrefrigerated, who knows how many times...
We later also find out that Coach Beiste eats a whole rotisserie chicken at every meal - until she's burdened with the musical, student council elections, football, etc, discovers that Breadstix delivers, and starts carbo-loading on enormous bowls of pasta. A damn' good trencherwoman, Shannon Beiste.
Miley Stewart's father Robbie Ray is very often seen at home raiding the fridge, and his expanding waistline is a Running Gag on the show.
Both Alex and Max from Happy Endings. It's more notable in Alex's case because she's tiny and petite, and Max is depicted as more of a fat guy, despite having a basically average build. Still, when the petite 5'3 girl and the 5'10 guy are eating roughly the same amount of food, you know which one is playing the trope straighter.
Iolaus from Hercules: The Legendary Journeys has a hearty appetite. Slaying monsters probably burns more calories for mortals than Demi-Gods.
Heroes: Sylar is often seen snacking on something and clearly enjoyed eating an entire pie by himself. A video montage was collected of how many times he's been seen onscreen with food. He also makes frequent references to food and his desire for abilities is often described as a "hunger".
Drop-In Character Nudge on Hey Dad..!. One of his major reasons for dropping-in seemed to be to raid Martin's fridge.
What boy on House of Anubis doesn't fall under this trope? It's most notable with Mick, Alfie, and Eddie.
Even the actors acknowledged Mick's tendency to eat; his eating scenes are written in the script. Apparently, the actor isn't much better, either.
With Alfie, not only does he always eat- he eats a lot. And it's rather messy, too. He's the one who once almost ditched Sibuna to eat Trudy's cookies instead while the students were under lockdown and not allowed to eat anything Victor didn't allow them to.
Eddie is nearly as bad as Alfie is, though at least he can separate his duties from lunchtime.
On How I Met Your Mother, Lily (played by the thin Alyson Hannigan) loves food. She once won a hot-dog eating contest ("29 dogs in eight minutes"), earning her the nickname "Lily the Belly." In a moment of Leaning on the Fourth Wall, a flashback to the contest had Lily standing up to reveal a swollen stomach—Hannigan was pregnant at the time and the writers decided to have some fun with the Hide Your Pregnancy trope by devising a way to show her actual baby bump.
I Think You Should Leave With Tim Robinson: "55 BURGERS, 55 FRIES, 55 TACOS, 55 PIES, 55 COKES, 100 TATER TOTS, 100 PIZZAS, 100 TENDERS, 100 MEATBALLS, 100 COFFEES, 55 WINGS, 55 SHAKES, 55 PANCAKES, 55 PASTAS, 55 PEPPERS, AND 155 TATERS!"
In From the Cold: To make up for the iron lost from her body morphing, Jenny gorges on foods rich in it after (largely meat).
Tuppy Glossop: I am not devoted to food! I have a healthy appetite.
Kousuke Nitoh on Kamen Rider Wizard. He practically eats anything and usually uses mayonnaise to top his food, even on food that wouldn't make sense with it. His Phantom is an even bigger eater, consuming Phantoms whole. In fact, he requires Nitoh to feed him Phantoms, lest he eats him next.
Kel from Kenan & Kel. In one episode, Kenan leaves Kel alone with the Thanksgiving turkey. He comes back a few minutes later and is horrified to find Kel has reduced it to bone.
Knots Landing: Michael's seemingly limitless appetite is a Running Gag from Seasons 6 to 8. His cousin Brian inherited this characteristic in Season 8 and the gag continued until his departure in Season 10.
Samantha Marquez on Las Vegas is Front of House's secret weapon during a hot dog eating contest against Back of House, despite Vanessa Marcil looking like she's never even touched a hot dog. Sam brags that her nickname used to be "Hummingbird" since she could eat twice her body weight.
Li'l Horrors: Aside from his stupidity, Duncan Stein's other major character trait is his gluttony.
Clark from Lois & Clark can put away a lot of food in one sitting. He especially has a particular fondness for junk food, leaving Lois to ask how he can eat all of that and still have a muscular physique, as well as if she can do it too. Of course, being Superman, he doesn’t have to worry about the consequences from all those excess calories.
The Longest Day in Chang'an: When he's first sent on his mission Xiao Jing is more interested in eating at every restaurant he sees than hunting the Wolf Squad.
In an episode of M*A*S*H Klinger tried to become a Big Eater when he learned that obesity could get you kicked out of the army. Like many of his hair-brained schemes, eight large salamis gives him a really bad tummy ache.
Radar can put away a lot of food. Justified seeing that he's supposed to be about 19, so his metabolism is probably still very high. He's noted as being one of the few people who doesn't seem to be put off by the food served in the mess tent.
Tommy was a Big Eater in one episode temporarily when the Monster of the Week, a Villainous Glutton, miniaturized itself and tricked Tommy into swallowing him; the idea was to act as a Trojan Horse to get to the Command Center, but it gave Tommy an uncontrollable appetite.
NCIS's Ellie Bishop, to the sheer amazement of her coworkers. Tony even suggests that the reason they've never met her husband is that "you had him with some fava beans and a nice Chianti". When he does finally meet the guy, his first question is "How the hell does she eat like that?" It's also practical, as she associates memories with food.
Similarly, NCIS: New Orleans's Meredith Brody, frequently seen wolfing down the delicious New Orleans food.
On Ned's Declassified School Survival Guide, there's a student known as "One-Bite" who can, as his nickname implies, consume any food item in a single bite, making him The Dreaded during lunch time. Once he actually left behind a small scrap of Ned's sandwich, but that was because he only took a "tiny" bite.
Sam from Nowhere Boys. In the first episode he's so hungry he eats cream for itchy crotch by accident (it's fruit flavored).
In a second season episode Sam is hypnotized by the school counselor. He's asked if he can recall the two weeks he was lost (in the other universe, which the boys are all desperate to keep secret). He says he can... then, hilariously, he proceeds to list under hypnosis everything we saw him eat in the other universe.
Counselor: (exasperated) Okay, can you remember anything other than food?
Sam: Yes.
Counselor: Good.
Sam: Jake's porridge. That wasn't food.
Otto from Odd Squad eats nearly anything and everything. His appetite is so huge that in one episode, "The Confalones", he manages to put away an absurdly large amount of food at the eponymous restaurant, evidenced by the stacks of plates littering the kitchen. The only thing he's shown to find disgusting is the egg salad pizza that Delivery Debbie and Delivery Doug create. Despite the amount of food he eats, however, all he has is a small pudge and mostly appears thin.
Omar, an Expy of Otto who debuts in Season 3, can also pack away a lot of food. The same goes for Oswald, who is a loose expy of Oscar. In "Raising the Bar", the two of them manage to pack away three pies in one sitting, and are still up for eating another pie. O'Wow even mentions that the two of them have eaten more pie than any guest the Graphing Headquarters has ever had.
Oprah has quite the appetite of her own, drinking one thousand juice boxes on the daily. When her former partner, O'Donahue, finds out, he's in complete shock, and by "The Voice" she's cut back to one hundred as her daily rations. Her opposite, seen in "O is For Opposite", is no slouch in the appetite department either, and manages to scarf down five egg salad sandwiches in one sitting. By the time Olympia and Otis catch up to her, she's happily chowing down on a tub of egg salad because Delivery Doug ran out of bread to make more sandwiches with.
In "Odd Beginnings", Omar, Opal, Orla and Oswald work together to eat their way out of a cinnamon bun trap that goes up to their shoulders.
Emma Swan on Once Upon a Time is always seen snacking on something. Justified in her Dark and Troubled Past as a foster child and runaway, she never could predict when her next meal would be, so she ate whatever she could get her hands on.
Emma: Where I come from, if you don’t eat fast, the big kids would swipe things off your plate.
Walter Denton on Our Miss Brooks. It usually manifests when he arrives at Mrs. Davis' house to drive Miss Brooks to school. He usually asks for and eats a Mountain of Food. This is always after having breakfast at home. As a teenaged boy, it probably comes with the territory.
Leslie Knope eats a massive amount of junk food, especially waffles, sugar, and whipped cream while managing to stay pretty slender.
Ron Swanson suffers from Testosterone Poisoning and has a manly appetite to match, particularly when it comes to meat and breakfast foods. Often to the consternation of waiters.
"Just bring me all the bacon and eggs you have. Wait. I'm concerned that you just heard 'bring me a lot of bacon and eggs'. What I said was 'bring me all the bacon and eggs you have.' Do you understand me?"
Person of Interest has Sameen Shaw, who is the smallest member of Team Machine, but is frequently shown eating and gets hungry easily.
Resurrection: Ertuğrul: Bamsi Beyrek embodies this trope. He may be a powerful soldier on the field, yet he typically won’t be satisfied to engage in military conduct unless he eats a large hunk of meat beforehand. Heck, he’s even been known to recover from serious injuries or conditions after getting his hands on some comestibles on a few occasions.
On Riverdale, much like in the comics, Jughead loves food and is always eating despite being played by the fit and muscular Cole Sprouse. He even managed to finish the entire cake for his birthday. Lampshaded when Archie laughs at Jughead's decision to go on a hunger strike.
The Coneheads from Saturday Night Live and their love of "consum[ing] mass quantities." In The Movie, the daughter eats a footlong Subway sandwich in about two seconds.
An episode of Stargate SG-1 has the team's metabolism boosted by alien devices. The sneak off base and go for steak. Jack orders three steaks and calls the waitress back with the "That's just for me" line while Carter and Daniel order the same. Then Carter adds And a Diet Coke. (When she gets the look, she explains that she likes the taste.)
From Stargate Atlantis, Dr. McKay is a big eater. He's not terribly discriminating, either — the only thing he doesn't like about airline food is they won't give him seconds. Except for any food including citrus, which he's allergic to.
Chuck Noblet in Strangers with Candy is constantly eating at his desk, which turns out to be foreshadowing for "Feather in the Storm" when we find out he's bulimic.
Tiny, pubescent Eleven from Stranger Things practically inhales Eggo waffles and in one of her first appearances, cleaned up a basket of fries, burger, and ice cream; justified in she is psychic and replenishing her energy.
Dean Winchester of Supernatural eats constantly and spends most of his life sitting in a car, but still manages to look as toned as Jensen Ackles. All the "Dean eats constantly" jokes have been getting slightly jarring recently because Jensen Ackles looks like he's lost even more weight while Jared Padalecki (the one who's never seen to be eating) looks like he could bench-press him easily.
Leviathans are found out to not only want to turn humans into livestock, they also want to kill anything else that might eat humans because there's only seven billion of us.
Ninja Sentai Kakuranger has Seikai, whose appetite actually gets exploited by Gakitsuki, the Monster of the Week for Episode 7, who enters Seikai's stomach and forces him to eat nonstop, eventually causing him to bloat until he reaches kaiju size. The rest of the episode revolves around getting the Youkai out and returning Seikai to normal.
Latka Gravas is sometimes featured as this: Louie once asked the cabbies to take one chocolate from a box. Then Latka began to eat the entire box except for one chocolate. Louie then lampshaded this:
Louie: I said "take one". Latka: I thought you said "leave one".
Latka's wife Simka also appears to be this, as Latka himself remarks that one thing he loves about her is that she eats like a pig.
Julius Nicholson from The Thick of It: "A man cannot live on Jaffa Cakes alone — I've tried".
Trick: Ueda Jiro, physics professor, ate a year's worth of rice in one day, then later in the episode (chronologically) ate a pot of rice that had been meant for over a dozen people.
Twin Peaks: Fit and slender Agent Cooper is always gorging himself on large quantities of unhealthy food. He orders a very large and unhealthy breakfast at the Great White North in an early scene. He matches the local cops in eating large quantities of donuts. Most notably he belts down the local diner's pies at every opportunity. The sheriff marvels that he must have the metabolism of a hummingbird.
Veronica Mars: Wallace Fennel, as he's a basketball player who needs the energy:
Wallace: The day of the back-to-school athletics banquet there were spirit boxes in our lockers. There weren't any brownies in there, but there were cookies. Veronica: Did you eat one? Wallace: I ate six. Veronica: That's my Wallace.
The West Wing: Ainsley Hayes — the trope namer for Blonde Republican Sex Kitten — likes to finish her statements with, "Are you going to finish that?" and a common Running Gag is her hunting for something to eat. That said, she doesn't eat as much as most people on this page.
Pat Sajak and Vanna White really go out of their way to sample local cuisine whenever Wheel of Fortune tapes on location. This was even referenced on a Clip Show (the 4,000th nighttime episode), which showed footage of Pat and Vanna indulging while "Eat It" played.
Alex Russo of Wizards of Waverly Place. Her parents run a sub shop, and she often takes customer's orders for herself or finishes off their leftovers. She sometimes takes the dispensers from the tables in the shop and empties them directly into her mouth. She keeps an assortment of inappropriate food in her locker at school, including pizza, popcorn, milkshakes, whipped cream, and maraschino cherries.
Alex's Boyfriend, Mason can be this at times due to being a Werewolf. In one episode, he consumes all of the meat in the sub shop almost instantaneously without any ill effects.
Word of Honor: Ye Baiyi eats so much that an astonished crowd gather to watch him eat.
On the Mexican telenovela Amigas y rivales, Irene is a fat girl who eats al the time, to her own frustration and also to the frustration and disgust of her friends, especially her best friend Tamara and Luis, the boy she's in love with. Irene does this as a self-defense mechanism after her father's suicide, and also when she is sad, depressed, anxious or afraid. Seeing the boy she loves dating her best friend and even mocking her obesity only makes the situation worse.
Ñoño from El Chavo del ocho, obviously as a joke that he’s fat. He generally competes with Chavo as the most glutton character. In his case is for the exact opposite reason; Chavo is glutton because he’s poor and is always hungry, Ñoño is glutton because he is rich.
One episode of CSI dealt with a man whose brain did not process "full" signals from his stomach, and therefore constantly felt hungry. If he was not physically restrained, he would eat every morsel of food in the house and continue foraging for more. (He died of a ruptured stomach in the wake of an eating contest.)
The Dukes of Hazzard features one of the more famous comedic archetypes: Boss J. D. Hogg. He's not only a Fat, Sweaty Southerner in a White Suit, but the show frequently demonstrates his big appetite, either by displaying a big meal he's about to eat or by showing him reaching for something else to eat.
Uncle Phil from The Fresh Prince of Bel-Air. Just listening to him fantasize in the midst of trying to lose weight will tell you exactly how much he likes to eat.
Friends: Monica Geller was shown to be like this as a child, most likely related to her numerous compulsive tendencies. Her parents were even once shown asking her to eat excess Thanksgiving leftovers when they ran out of space in the fridge and the show presented this as a typical request.
Bob Duncan from Good Luck Charlie has a huge weight gain from his obsessive eating always digging on food for whatever the reason and is made fun of by his family (mostly Gabe) for this. He also can be manipulated with Food as Bribe. However, over the course of the series, Bob starts to lose weight and gains a Heroic Build.
One of the defining characteristics of George IV on Horrible Histories. During Georgian Come Dine With Me, he is the only able to eat the curry. He then looks at everyone else's unfinished portions and asks "Are you going to eat that?".
How I Met Your Mother has Marshall, though he's mostly big because of how strong and muscular he is rather than his eating.
It seems to run in his family. A Thanksgiving episode with his family has his fiance Lily learning how to make a seven layer salad from Marshall's mom, which include 16 cups of mayonnaise.
Don Wilson on The Jack Benny Program, although not nearly to the extent of how he was characterized in the radio version.
Bertram the lazy butler from Jessie is massively overweight and is always napping and rarely doing his job. He even has trouble reaching for the remote because it's "too far". He also orders much food and invades the fridge many times.
Smul from Studio100's Kabouter Plop series is the biggest gnome and is always seen eating sweets and cookies. But what he really loves eating is tarts and cake.
More "moderately overweight" rather than "fat", but Law & Order: UK's DS Ronnie Brooks is one, enough for it to be a Running Gag — his partner and supervisor tease him relentlessly and anyone who wants a favor knows to bring him a snack. There's a legitimate explanation for this — he's a recovering alcoholic and has replaced his craving for liquor with one for sugar.
Lost's Hurley is a compulsive eater and extremely overweight. Since the DHARMA products were discovered in Season 2, he has been seen hoarding food and gorging himself at times. This was needed to Hand Wave the common question of why Hurley was not losing any weight despite being stranded on an island, but also added to the character's Back Story.
Adam Richman from Man v. Food. His rigorous exercise just barely keeps him in Hollywood Pudgy territory.
Monk features an evil version of this trope in the massive form of Dale "the Whale" Biederbeck, an Information Broker and Corrupt Corporate Executive who is both an Evil Genius and so enormous (800 pounds for the majority of the series — and this is the lowest his weight has been for some time) that he has been totally immobile and confined to a bed for eleven years. It's revealed that Dale, already 400 pounds to begin with, fell into a horrific depression after his mother died and coped with the pain by eating non-stop—apparently he would call restaurants and have them deliver every single item on their menus. Even after being put on a special diet and looked after by a personal physician, Dale is still shown devouring huge quantities of food whenever he gets the chance.
In Mystery Science Theater 3000, it's not uncommon for Joel, Mike and the Bots to portray heavyset characters as this trope. Of special note is the Novicorp Chairman of Overdrawn at the Memory Bank, whose rotund and greasy look make him look like he's constantly hungry — the first riff out of anyone's mouth when he fully shows up and a lackey asks what they were going to do when Aram Fingle's body is lost is Crow booming out "EAT!"
Sylvia Fine on The Nanny crosses the line between this and eating machine, especially in the episode where she subs as a nanny while Fran is on jury duty.
Niles: Sylvia, did you say you wanted waffles or pancakes?
Sylvia: "And", I said, "And".
Fran is not far behind Sylvia, neither is Yetta nor Fran's dad. It's a Fine Thing.
Ron: Just give me all the bacon and eggs you have... Wait, wait. I worry what you just heard was, "Give me a lot of bacon and eggs." What I said was, "Give me all the bacon and eggs you have." Do you understand?
According to the book Pawnee: The Greatest Town in America, four times a week Ron eats a meal at JJ's Diner called the "Four Horse-Meals of the Egg-Pork-alypse", which consists of a 12-egg scramble, bacon, ham, sausage, hash browns, chicken-fried steak, and a huge stack of buttermilk pancakes.
He can also eat a party platter meant to serve 12 people in four minutes.
At some point, he starts scouring various restaurants he's visited with Tom to make sure there's no personal information about him out there; the one we see him visiting is one where he won a spot on the wall of fame for eating 51 eggs in one sitting, "Couldn't cook 'em fast enough, the last ten were still in the shell!" And then, after taking his picture off it...
Ron: Let's go.
Tom: ...where are we going now?
Ron: I've eaten a lot of food, at a lot of restaurants! *aside* Why is everyone else so bad at eating...?
Sadakatsiz: Suna, the Güçlüs' nanny, is a chubby woman whose weakness is food. And whose it wouldn't be when you work for a rich family? While not an overplayed trait (her being good with kids being far more prominent), it can sometimes be seen in light-hearted moments. Especially when the Güçlüs' drama becomes too much. For example, when Derin is too unhappy to eat due to marriage problems, Suna silently eats the fruit pie slice Derin rejects (along with the rest of the pie, really). When Derin's mother Gönül goes to grab another slice, she finds none and teases Suna for it. On another occasion, Gönül's friend Cavidan brings spinach pies to cheer Gönül up (she is upset over her daughter slowly ruining her own life). Suna offers herself to take the cake to the kitchen, only for Cavidan to refuse and jokingly say that Suna will surely eat all the pies before anyone else has a chance.
Newman on Seinfeld is frequently shown eating massive amounts.
Pretty much everyone on The Sopranos, bordering on Food Porn. They're eating in every episode: big, heavy, Italian meals of pasta and meat and sauces and alcohol.
Kirby the Security Guard from The Suite Life on Deck keeps a stick of butter in his pocket because he doesn't like gum.
Tales from the Crypt: Charlie, in the episode "Dead Right", given how grossly overweight he is. It's even pointed out on the news, after he's arrested, convicted, and executed for Cathy's murder, that his last meal was the largest any Death Row inmate has ever had.
Wizards of Waverly Place: Jerry is very lazy and likes to eat food out of the garbage. He even rigged the Family Wizard Robe to have an unlimited supply of hoagies in the left sleeve.
Young Sheldon: George Sr. has a voracious appetite and is the fattest person in the Cooper household.
was collected of how many times he's been seen onscreen with food. He also makes frequent references to food and his desire for abilities is often described as a "hunger".
