Axe Cop eats nothing but cake and wish food, but he's always incredibly fit and ready to fight crime. Then again, it might be subverted: he only sleeps two minutes a day, and spends the other 23 hours and 58 minutes fighting crime. He must burn calories like Guy Montag burns books.
Brother Complex: As a side-effect of her new body, Rose has become this, first exemplified when she makes a large order at a fast food stall... then asks Jack what he wants.
In Charby the Vampirate Menu is constantly hungry and getting food is a constant concern for him. He once ate a meal intended for everyone in the cabin, when there were sixteen of them. While he occasionally gains a little weight in his stomach after gorging himself it goes away very quickly as his constant hunger and burning through food is a side effect of being a werewolf.
Craving Control's lead character was a coed named Lalia, who was implied to actually have a binge eating disorder, but you wouldn't know it from her slim, extremely busty figure. This was eventually subverted as in one of the last strips, eighteen years of overeating finally caught up to her and she woke up with thicker hips and a noticable pair of love handles. Guess she finally ran out of room for fat in her breasts.
Diamond Tiara. Granted it's usually her cat Dazzle who eats more but she's no slouch. In two such instances where she becomes a cat, she has to work off the weight she gained from overeating.
Imp when he's also turned into a cat also becomes one when he helps Diamond finish off Torpedo.
Furry Experience: Cat is a seemingly 90-pound girl who makes sandwiches out of entire bread loaves, eats them in one gulp, and can polish off a tub of ice cream in five minutes [1].
Muko from Furry Fight Chronicles can eat a lot. She even tried to exploit this by becoming a competitive eater.
General Protection Fault: Fooker is well-known for having a truly rapacious appetite at times. Normally, he seems to have standard desires for food, but when it comes to some kinds of junk food, especially pizza, he can put enough away to put the Flash to shame. He's twice now nearly driven a pizza place (run by the same guy) out of business due to eating all of their merchandise and earned multiple lifelong banning for it.
In Gnoph, hosts to Gnoph symbiotes have to eat large amounts of food. If they use too many Gnoph powers without eating enough, the Gnoph will start to consume body tissues for energy. Abbey, who grew up homeless and was therefore never able to get enough food, is anorexic to the point of Body Horror.
Later, at a roadside pancake place the girls stop at on their road trip, Grace became one of only four people to eat the entire Pancake Mt. Doom Meal. This consisted of a dozen flapjacks, a variety of fruit fillings, sides of bacon, sausage, hashbrowns, three kinds of syrup, and your choice of eggs. The best part is that "Andy Debtman, Eater of Food" from Man Engulfs Food arrives to take on the challenge, and stands in front of the Wall of Fame filming his introduction when Grace's photo is added.
If you look carefully, the Beat Panel has Andy still staring at Grace's photo after her photo was put on the wall. Given that the three other photos on the wall are of notably large people, he's probably in a bit of shock to see such a skinny person polish off the huge meal and retain her appearance.
Cadi from Hexenringe has enough of an appetite that she doesn't mind grabbing someone else's chow in this episode.
Tiger in Housepets! is a parody of Garfield who consumes more food than should be possible under the laws of physics, never mind biology.
Shin-Ae of I Love Yoo. At the beginning of the story, Shin-Ae is very food-motivated, however, this is toned down in later episodes.
Molly and Galatea, the pink furry peanut butter monsters in The Inexplicable Adventures of Bob! both have very high metabolisms (they grew from infancy to maturity in a month's time, and are fleet-footed enough to outrun a bear at full gallop) and will eat enormous quantities of any kind of food. Molly has reservations about eating peanut butter, though, saying it makes her feel "kinda cannibalistic".
The aptly-named Hungry Nun from Little Nuns is almost always eating. Her being thin despite this is justified, as she's also a Passionate Sports Girl.
Lardee from My Milk Toof who is a milk tooth ate a chicken.
Iki from Off-White likes to wolf his food down. It's a wonder his pack mates tolerate this behavior, considering he's useless when it comes time to hunt.
Dee from PHD, who even sneaks out in the middle of an exam to get food.
Seekers: Giselda will scarf anything that is set in front of her. Especially when it doesn't belong to her.
Very early in The Senkari Freija apparently eats 3 Burgers without breaking stride. Possibly justified as being a full-time Action Girl she burns through a lot of energy.
Sluggy Freelance: Other characters often make reference to Gwynn "scarfing down" some sort of food or another (which she always angrily denies), but despite having eaten more recently than most of the rest of the cast, she's the first to get hungry when they're all trapped in the ass of hell. Well, first human, anyway.
Supermegatopia has the minor villain Piranha Girl, a genetically modified super-villainess who suffers from a rapacious hunger that sees her regularly eating twice her own body weight in a sitting, yet still being a slenderly built woman. Oh, and that hunger has apparently led her to eat people.
Justified in Surprising Octeal. Main character Suzanne Incirrina mutated to have four octopus arms and as a consequence is a heavy eater.
Thaumaturge: Befitting a webcomic that prides itself on its Shounen roots, Nomen's appetite is through the roof.
Too Much Information (2005): the kittens. They're just ordinary-sized kittens, but there doesn't seem to be any limit to how much they can consume. Nor do they appear to have much in the way of discrimination, either, since they'll happily devourer anything in the kitchen.
Vampire Girl: After Levana becomes a mortal, and is able to actually eat food that contain certain seasonings that she doesn't have to worry about potentially killing her (like garlic for instance), pizza not only becomes her favorite food, but she is able to eat several slices in single sittings, and has even noted in her diary that during one such sitting, she lost count of how many slices she ate after her twelfth.
Robin DeSanto of It's Walky! eats tremendous amounts of candy, as a justification of her Super-Speed. Both her Super-Speed and Big Eater habits have been played down (But not removed!) since she moved to Shortpacked!.
Walky had occasional Big Eater moments as well, usually involving his favorite snack food DoritosNachitos. At one point it's revealed that this is all Walky ate back then.
Joyce also eats more than she should be able to and maintain her figure. When Walky eats similarly, he starts to gain weight.
Being a gluttony demon, Damien from White Dark Life is typically seen eating a snack and never changing in size. In fact, the only time he gains weight is when he becomes an adult and(logically) becomes taller. His daughter is more of a big drinker given her love of Orange Juice.
Fat Characters
Shannon from Bloody Urban. Has been known to clear out entire vending machines in minutes, and has eaten classmates whole as a child. Though he was forced to let them out afterwards.
Stump from Beyond the Canopy is nearly always depicted with food in hand.
Bridgette's Belly: Excluding pregnancies, Bridgette does tend to fluctuate between a little chubby to a much more heavyset frame, at least in the early strips.
Emerald Jaegar, from Heartcore, is shown ordering food for at least three people, then eating it all herself.
Other Daryl Wolf in Housepets! is overweight, which is the main thing that distinguishes him from his brother, Daryl Wolf. He also once beat Tiger (see above) in an Eating Contest, and his reaction was to ask how many hamburgers he could get for the prize money.
Ana and Bree from Kurami. Bree is known to take "all-you-can-eat" to extremes, while one Halloween strip has Ana buy a massive pile of candy only to admit it's all for herself.
Tim of Looking for Group got sick and puked his lunch... which turned out to be a live oryx.
Youko from Muertitos and Tsugumi from Gorgeous Princess Creamy Beamy. Both comics are drawn by the same author, who has an admitted preference for fat chicks.
S-Class Hero "Pig God" from One-Punch Man is Big Eater taken to the level of a superpower. He can eat a seemingly limitless amount of food, seems to be able to process anything "organic", can distend his jaw to fit truly massive items, and kills monsters by swallowing and digesting them. Whenever one of his meals is shown, it's a literal tower of dishes.
The titular character of Rosianna Rabbit is quite pudgy and frequently shown to love eating food. One strip even has her fail her New Year's Resolution to eat healthier due to continuing to eat junk food and winding up even more obese by December.
Jeremy from Split Screen. Eats as a coping mechanism. Weight fluctuated through the comic's run but was never below "pudgy" — save for flashbacks.
Hyper Hippo. Like most speedsters, she has to eat a lot to fuel her powers; unlike most speedsters, she does store the extra energy as body fat (she is an anthropomorphic hippopotamus).
There's also the gluttonous canine sorceress Red Stephie from the side comic Crushed: The Doomed Kitty Adventures.
Mad Scientist Dr. Nesbit displays a huge appetite for donuts during her stint in the Weasel Boy comics, where her current "evil plan" is using a machine that drains energy from the city's power grid and converts it into donuts. She causes several city-wide blackouts in the process of creating small mountains of donuts, which she eats singlehandedly, visibly packing on poundage as a result of her gluttonous indulgence. True to form, as a Mad Scientist, she brushes off an observer's comments about her weight, assuring them it's a temporary side effect that will be undone when the donuts revert to energy... completely ignoring that fat cells are created to store energy for the body's use.
In Zeus' Godly Goodtime,Fat Princess' gluttony gets the better of her when she eats King Dedede's birthday cake. Evidently, she didn't learn her lesson, because she then goes on to eat Sweet Tooth's ice cream.
The titutlar character of Tony Comics is a huge glutton, whose shown being capable of consuming huge amounts of food at a time and even sleep-eating in one comic. One comic even mentions that as a brown bear, he eats pretty much everything.

It's Impossible to Tell
Rowan and Murphy from Boy and Dog are both average-sized and both love their food. Rowan apparently has two breakfasts, brunch, and elevensies, while despite pretending not to be hungry, Murphy likes food as well.
Dazzle from Diamond and Dazzle will eat any kind of sweets, even if he's already full. Needless to say, his weight has fluctuated throughout the comic.
Professor North Dakota Jones of Irregular Webcomic!, who has been known to order for two at all-you-can-eat restaurants and can go on about food for hours given the opportunity. You can't tell which heading he's under because he's Built with LEGO and thus appears to have exactly the same build as every other character in the "Cliffhangers!" theme.
After only two adventures, it is evident that the knight protagonist from Legend of Legendary Mighty Knight is primarily motivated by food. The knight crushes some brigands so that they can eat an entire banquet themself (that was meant for someone else, no less).
It's mentioned that a lot of the people in the agency in Manly Guys Doing Manly Things are this, to the point it's deconstructed: they've run so many all-you-can-eat restaurants out of town that the Commander and Ganondorf beg Jonesy not to tell the rest of the guys about the one they're currently at. It's placed in this category because there's people of both types in the agency.
As with her animated counterpart, Pinkie Pie from Slice of Life eats impossibly huge amounts of pastries, baked goods, and sweets, but never gains any appreciable weight over other ponies.
Pinkie Pie: "Betcha I can eat three cakes at once!" Pumpkin Cake: "You're on!"
Pebble from Pebble and Wren can eat a lot in one sitting and really loves his food. He does get full, but it takes a lot of food to fill him up.

Princess Kaira from Restaurante Macoatl switches from being chubby to being thin depending on the storyline.
Big Ben from Weak Hero can eat six slices of pizza at once and obsesses over the chicken at his local fast-food stand. While he is stocky, as his nickname would suggest, he burns off all the food by exercising so that he's muscular instead of overweight.
