->"So I'm on a diet... Big deal. You know what a "diet" is, don't you? '''It's "''die''" with a "T," that's what it is!'''"
-->'''''ComicStrip/{{Garfield}}''''', [[http://www.garfield.com/comics/vault.html?yr=1978&addr=780830 August 30, 1978]]

A character is sneaking out to the kitchen for a midnight snack. He is careful not to wake up his wife or else he'll get caught. The minute he opens the refrigerator, he suddenly hears footsteps, so he turns around just in time to see his wife standing [[RightBehindMe behind him]] with a stern expression on her face. The wife then promptly puts her husband on a diet for trying to raid the refrigerator at night.

This is a type of episode that shows up in almost every form of media. When a character is caught trying to eat more than he usually does, he will promptly be put on a diet, or the character decides to go on a diet himself.

!'''Examples'''

[[AC: {{Anime}} and {{Manga}}]]
* There is one in ''Manga/KamenNoMaidGuy''.
* ''Manga/AzumangaDaioh'''s Yomi is seemingly always on a diet. Her [[ADayInTheLimelight Day in the Limelight]] episodes often feature her trying several unsuccessful diets.
* Usagi tried to go on a diet but failed in an early ''Manga/SailorMoon'' episode that involved the villains taking energy from girls who were obsessed with getting thin.
* There is also a ''Anime/YesPrettyCure5'' episode where Coco goes on a diet because he got fat (although you never really see the difference in his human form) from eating too many cream puffs.
* ''Anime/PantyAndStockingWithGarterbelt'' has one in which, thanks to a Ghost, Stocking finds herself gaining weight (something that never happened before, considering [[GagBoobs all the fat she consumes goes to her breasts]]) and starting a [[MemeticMutation DIETO]].
* One episode of ''{{Manga/Gintama}}'' features most of the major female characters having become obese within the same time period and enrolling into a fat camp. They all go back to normal at the end of the episode after eating laxitive-laced chips.
* Episode 8 of ''Anime/TamakoMarket'' focuses on [[spoiler:[[TalkingBird Dera]]]] taking a diet, as he has been overly obese to carry out his duties.
* As every episode in ''WebComic/AxisPowersHetalia'' is only five minutes long, that one is more of a diet skit. [[BigEater America]] gets worried about his weight after a casual comment by England. After he spends the skit asking different nations for diet advice, a note says that what America doesn't realise is that the reason for his rising weight isn't actually fat, it's muscle.
* Chapter 64 of ''Manga/GekkanShoujoNozakiKun'' has Sakura and Mikoshiba trying to lose weight out of fear that they've become fatter. They first attempt to simultaneously exercise their arms whilst doing their manga work, then they have Mayu help them with their work-out routine. It's all for nought when they go to Nozaki's house and see that he's baked a cake for them.

[[AC: ComicBooks]]
* ''ComicBook/{{Asterix}} and the Chieftain's Shield starts out with Vitalstatistix being put on a strict diet and sent to a health spa. We see the results near the end, where he's gone from 'round' to 'stick'. However, on his way home he samples food from the best inns, returning to his original girth.

[[AC: {{Literature}}]]
* The Dursley portion of ''Literature/HarryPotterAndTheGobletOfFire'' involves Dudley being put on a diet. Unfortunately, the Dursleys decided that to accomodate Dudley, everyone ''else'' needed to participate, including Harry (the ''last'' person who actually needed such a thing).
* ''Literature/JellyBelly'' fits the bill for its first half, subverting the trope once Ned gets serious and realizes cutting out junk food isn't as torturous as he thinks it is.

[[AC: LiveActionTV]]
* ''Series/{{Roseanne}}'':
** One PlayedForDrama series of episodes, where Dan is put on a diet following his heart attack. It eventually leads to the largest fight Dan and Roseanne ever had on the show.
** In season two it's played for humor as usual, with Roseanne insisting they both go on a diet after she has trouble fitting into her pants. Dan seems to do fairly well, but Roseanne ends up nearly cracking after watching three food commercials.
* A major plot arc in ''Series/{{Frasier}}'', as Daphne started gaining weight after she got together with Niles. She was put on a regimen and eventually sent to some sort of fat camp. This storyline was a clever trick used by the writers to mask the fact that Jane Leeves was actually pregnant.
-->'''Niles:''' She's just lost [[LampshadeHanging 9 pounds, 12 ounces]].
* In one episode of ''Series/ThePartridgeFamily'' Danny is teased for being fat, goes on a diet, and loses like 10 pounds, all without being noticibly slimmer. According to Danny Bonaduce's biography, it was not a pleasant episode to film.
* In an episode of ''Series/EverybodyLovesRaymond'', Marie decides that everyone needs to eat healthier. Unfortunately, it was the Thanksgiving Special...
* ''Series/GilligansIsland'' had an episode where the Skipper revealed that he'd probably rejoin the Navy if he ever got back to civilization, then found out he was overweight and went on a diet.
* On ''Series/{{MASH}}'':

** In a humorous inversion in the same episode, Klinger begins eating everything in sight after he finds out he can be discharged if he's overweight.
* ''Series/{{Glee}}'' had an episode where Sue made Mercedes go on a diet in order to remain on The Cheerios. Sadly, this so-called "diet" resulted in Mercedes obsessing over her weight and starving herself, prompting Quinn to intervene.
* PlayedWith on ''Series/BabylonFive'': [[DaChief Garibaldi]] is ordered by Dr. Franklin to go on a restricted diet (or rather... a ''[[InsistentTerminology food plan]]'') because of various problems his body is suffering due to the after effects of being shot InTheBack by TheMole in an earlier season. Meanwhile, [[TheCaptain Captain Sheridan]] is ordered to eat what he considers "Rabbit Food" because he has gained ten pounds since his previous exam. [[TheLancer Commander Ivanova]] is ordered to eat more because she is suffering nutrition deficiencies because she doesn't eat enough healthy food; in addition, this is messing with her recovery from her broken foot (from the previous episode).

* The Ronnie Barker one-shot "One Man's Meat".
* An episode of ''Series/TheSuiteLifeOfZackAndCody'' has Cody trying to help the hotel's chef lose weight. He manages to do it by telling him not to think of it as a diet, but a lifestyle choice. Additionally, Zack (who had become a glutton for sweets in the episode) is also put on a cold turkey diet, until his mother realizes it's too extreme and agrees to allow a small amount of sweets to curb his temptation. Meanwhile, one of London's socialite friends tells London she's fat and that Maddie is too skinny, so London spends the episode starving herself and working out, while Maddie gorges on food. London becomes exhausted from a lack of food and Maddie becomes too bloated to wear a dress for a model show (despite not appearing any bigger than normal), and the two accept their bodies when the socialite is revealed to be stuffing her bra full of toilet paper.
* There is one episode of ''Series/{{Poirot}}'' called ''Literature/EvilUnderTheSun'', in which Literature/HerculePoirot has to go on a diet at the Sandy Cove Hotel on Miss Lemon's orders after an incident at an Argentinian restaurant has sent him to a hospital where he is declared "medically obese". [[spoiler:It turns out at the end that the incident is not obesity or his health problems but food poisoning--nine cases of it in fact (Poirot's was one of them), so the restaurant had to be shut down until it can work out the food poisoning bit.]]

[[AC: NewspaperComics]]
* ''ComicStrip/{{Garfield}}'' has numerous strips where Garfield is put on a diet by Jon, and sometimes by Liz. In the earlier years of the strip, 'Diet Week' was a regular theme, explained by [[WordOfGod Jim Davis]]'s claim that when ''he'' goes on a diet, so does Garfield.

[[AC: Professional Wrestling]]
* Happened a few times in relation to light heavyweights, where there is a weight limit.

** During the build-up to ''WrestleMania 19'' in 2003, Matt Hardy was feuding with WWE Cruiserweight Champion, Rey Misterio. Smackdown GM Stephanie [=McMahon=] told Matt that if he could get down to the 220 pound weight limit (Matt weighed 227 at the time), she would make their match at WrestleMania a Cruiserweight title match. Matt then wrestled matches wearing a Sauna Suit under his ring outfit.

* ''WesternAnimation/OggyAndTheCockroaches'' has had two episodes: "Oggy's Diet" and "Dee Dee's Diet".
