->''Put in as much sugar as you possibly can...I'm about to use my brain, so I need all the sugar I can get.''
-->--'''[[MadScientist Kokonoe]] [[DrinkOrder orders coffee]]''', ''VideoGame/BlazBlueContinuumShift [[CapcomSequelStagnation EXTEND]]''

Thinking requires energy, right? [[TheSmartGuy Some]] [[TheProfessor characters]], [[InsufferableGenius of course]], do more thinking than others. These characters will need to have a quick pick-me-up on hand, and most decide to eat some sweets. Perhaps the origin of this trope is the idea that showing a character eating sweets is a way to give the viewer clues as to his hyperactive nature, and it is harder to show the genius's mental hyperactivity on screen than another character's physical hyperactivity. [[TVGenius Geniuses on TV also tend toward the socially immature]] [[CloudCuckoolander and]] [[AbsentMindedProfessor the]] [[MadScientist eccentric]], and showing them eating candy may be a clue to this. Even if a genius character isn't [[SweetTooth constantly binging on sweets]], if he has a TrademarkFavoriteFood, it is likely to be sweet in flavor.

Actually TruthInTelevision: the brain uses glucose as its primary source of energy [[http://en.wikipedia.org/wiki/Hypoglycemia and not getting enough is bad]]. Therefore, if you need to make your brains work a lot, you may need ''at least'' some sweet food...

Contrast IsItSomethingYouEat, where a character reveals his [[BigEater love of food]], and his [[TheDitz idiocy]]. Compare MustHaveCaffeine, which often overlaps.

* Skuld in ''Manga/AhMyGoddess''.
* Professor Nova in ''BattleAngelAlita''--pudding.
* Once ''Manga/{{Bleach}}'''s Ikkaku bribed Urahara with a lollipop, Urahara was seeing happily eating it with no problems.
** Orihime Inoue is a GeniusDitz who ''loves'' doughnuts, according to the latest manga arc.
* ''Anime/BurnUp'''s Nanvel Candlestick: a world-renowned, award-winning inventor who ''demands'' Godiva chocolates and other sweets before she can work on anything. She ''never'' misses her three-o'clock snack, or her After-Dinner Dessert.
* L and Mello from ''Manga/DeathNote'' both ate sweets ''constantly''. (In Mello's case, he was always ominously biting into some chocolate.)
* Spanner from ''Manga/KatekyoHitmanReborn'' loves lollipops and [[IncrediblyLamePun chain-eats them]].
* Itachi Uchiha from ''Manga/{{Naruto}}'' plays with this trope. His favorite food is cabbage and ''onigiri'' (rice balls) with seaweed, but his hobby is visiting sweet shops.
* Nousou from ''Manga/ElfenLied'' is seen regularly eating [[LawyerFriendlyCameo "Pocky"]].
* The Professor in ''Manga/{{Nichijou}}'' can always be expected to either be eating junk food of some kind, or trying to get someone to give her some.
* In ''Manga/PokemonSpecial'''s Sinnoh arc, Professor Rowan is shown to have a fridgeful of sweets in his lab in Sandgem. In one early scene, he devours a cupful of sweets in less than 5 panels...and asks his lab assistant if he could also have the untouched serving.
* Yakumo Saitou from ''Literature/PsychicDetectiveYakumo'', though it differs between versions: in the Oda Suzuka manga, it's ice cream and muffins, and in the Miyako Ritsu manga, it's doughnuts.

[[/folder]]

[[folder:Comics]]

* ''ComicBook/TheIncredibleHercules''' Amadeus Cho needs sugar to power his HyperAwareness. He prefers chocolate, to the point that he fills the Olympus Corp building with chocolate vending machines and instructs employees to report any shortages immediately.
* ''ComicBook/{{Chew}}'' takes this trope to new levels with characters who literally become geniuses when chowing down.
* The Chief of ''Comicbook/DoomPatrol'' is [[OmnidisciplinaryScientist an expert on many topics]], but gets very cranky if he doesn't have his chocolate.

[[/folder]]

[[folder:Film]]

* In the original cut of ''Film/{{Ghostbusters}}'', Dr. Egon Spengler's sweet tooth was a little more obvious. Still, it can be noticeably observed throughout the final product. (Venkman rewarding him with a candy bar, munching on a box of Cheez-Its, and of course, the Twinkie.)
** In ''VideoGame/GhostbustersTheVideoGame'' (which, according to WordOfGod, is canon) it's explained that, growing up, Spengler's parents fed him nothing but "brain food" (fish, eggs, potatoes, etc.) and thus his love of junk food borders on fetishistic.
* In ''Film/GodOfGamblers'', one of the titular genius gambler's distinctive traits is his love for chocolate (with a distinctive way of eating) which he keeps even after he got amnesia. The chocolate-eating habit is followed by his students in later movies, and, in one particular movie, an impostor (though he eats the wrong kind of candy and has a different way of eating).

[[/folder]]

[[folder:Literature]]

* Dumbledore from ''Literature/HarryPotter'' loved all sorts of candies, and the passwords for his office were always names of sweets. (Even something called Cockroach Clusters in one case.)
** The exception being Bertie Botts' Every-Flavored Beans, seeing as he always seems to have the misfortune of eating one of the nasty ones.
* This is one of the first things we learn about [[GadgeteerGenius Laura]] in the ''HIVESeries'':
-->'''Laura:''' These people seem to know that the way to a girl's heart is through her stomach.
* The title character in ''Literature/{{Swellhead}}'' by Creator/KimNewman has a first-class brain and is never without a sweet snack to hand.
* The mentats in ''Literature/{{Dune}}'' use sapho juice to boost their already considerable mental abilities. It is described as cranberry-colored and highly energetic, so it is probably sweet. Baron Harkonnen's "twisted" Mentat Piter De Vries also eats spice (which tastes a bit like cinnamon) like candy. The Baron doesn't mind paying for Piter's extremely expensive addiction since it helps him control Piter.
* Much to the disgust of [[TheWatson his partner]] Captain Hastings, Literature/HerculePoirot preferred hot chocolate to tea and liqueurs to cocktails.
* Lord Auditor Georg Vorthys from Creator/LoisMcMasterBujold's ''Literature/VorkosiganSaga'' is regarded as one of the Barrayaran Empire's top experts on Engineering Failure Analysis and has a Professor Emeritus post at Vorbarr Sultana University. He is very fond of desserts and makes regular trips to local bakeries to ensure that his supply of pastries does not run low. He also keeps a stash of cookies in his study.

[[/folder]]

[[folder:Live Action TV]]

* In ''Series/DoctorWho'', the Doctor loves his Jelly Babies. The Second Doctor was the first to mention them, but "would you like a jelly baby?" was the Fourth's CatchPhrase. The Eighth, Eleventh and Twelfth Doctors and Creator/JohnSimm's Master have homaged it.
** The Doctor seems to also like ridiculously sweet tea:
*** In one of the ''AudioPlay/BigFinishDoctorWho'' audios, it's revealed that the Eighth Doctor habitually takes his tea with six sugars. It might be more accurate to say he takes his six sugars with a spot of tea, really...
*** In the Fourth Doctor ''Magazine/DoctorWhoMagazine'' comic strips, it was revealed he took his tea with "just" ''eight'' sugars.
*** In "Death in Heaven", we see the Twelfth Doctor dropping handfuls of sugar cubes into his teacup. It's unclear how many he takes as the camera cuts away without him seeming to have finished, but he's shown putting in at least seven.
* Jarod from ''Series/ThePretender'' runs on PEZ.
* Dr. K of ''Series/PowerRangersRPM'' has actually sent the Rangers on shopping trips to the candy store. Her purchases are so large, the rangers must use a cart.
* Reid from ''Series/CriminalMinds'' always seems to be munching on something unhealthy, especially when he's thinking. It gets to be a RunningGag--the team will be investigating a crime scene without any obvious food sources, and then Reid will pop up in the background, having located a vending machine or snagged a piece of leftover birthday cake.
* In ''Series/{{NCIS}}'', both Abby and Gibbs seem to run on caffeine rather than sugar, though those Caf-Pow's are probably loaded with both.
* ''Series/{{Fringe}}'': [[MadScientist Walter Bishop]] loves his sweets: it's hinted at that he associates different types of desert with different Fringe Sciences.
* Brenda Leigh Johnson in ''Series/TheCloser'' has a thing for processed sugar products, as well as (unsuccessfully) trying to cut back. In one episode, her team gives her snack cakes to help with the case.
* The ''Series/{{Leverage}}'' team tech-geek Hardison loves his orange soda and gummi frogs.
* The entire point of the competitive dessert cooking show ''Series/SweetGenius''.

[[/folder]]

[[folder:Video Games]]

* In ''VisualNovel/ApolloJusticeAceAttorney'', Ema Skye conducts her forensic investigations while snarfing down her Snackoo's.
* Kokonoe of ''VideoGame/BlazBlue'' is a MadScientist DeadpanSnarker who is usually drawn holding a lollipop. Her lab, when the player finally sees it, has a few sweets laying around, too.
* While not a "genius" in the traditional sense, the ''Videogame/KingsQuest'' guide says that Graham has a big sweet tooth.
* Caillou from ''VideoGame/RecettearAnItemShopsTale'' is a child wizard who keeps an eye out for promotional mud pies and used to go to church for the candy.
* Professor Rowan from ''VideoGame/PokemonDiamondAndPearl'', although it isn't obvious. You first find out that he has a thing for candy if you check out the refrigerator in his lab at the beginning of the game. (It's ''full'' of sweets.) Later, when after you beat the game, you can find him in the lower floor of the Veilstone City Department Store; if you speak to him, he complains about the Rage Candy Bars still being out of stock before he speaks to you.
* Maxima from ''VideoGame/TheKingOfFighters'' is a GeniusBruiser {{Cyborg}} who unabashedly admits his love for sweets. Justified, as he's also a {{Technopath}}.
* Lemres from ''VideoGame/PuyoPuyo'' is a particularly interesting case. He's a senior mage from a neighboring school whose fame as the Comet Warlock is publicized for attaining his status before he even graduated school. Lemres also has a great affinity for sweets, and has a nigh endless stock of them and freely shares them among his peers. The twist? According to him, candy and sweets ''fuel his magic power''. In 20th anniversary, we get an episode of what happens if he abstains from having any sort of candy. It isn't pretty.
* According to ''VideoGame/MegaManBattleNetwork'', ChildProdigy Chaud takes his [[MustHaveCaffeine coffee]] with twelve sugars.

[[folder:Western Animation]]

* ''WesternAnimation/AmericanDad'' has one of the two CIA scientists who is more than willing to give away classified and potentially dangerous technology if offered Francine's brownies.
-->'''Francine:''' I brought brownies\\
'''Scientist #2:''' BROWNIES!!!\\
'''Scientist #1:''' ...He makes it hard to negotiate.
* ''WesternAnimation/TheMarvelousMisadventuresOfFlapjack'': in the episode "Skooled", Flapjack discovers that he can get candy (a task around which the entire show is centered) for correctly answering questions that the teacher asks. Despite never having been depicted in any sort of educational setting before then (he was raised by a whale) , Flapjack is able to answer the vast majority of the questions the teacher asks and it isn't long before he's so stuffed with candy he can't eat anymore and is unable to move. This does not deter him, however. After answering yet another question correctly he instructs the teacher to place the candy on his cheek, declaring that he'd get to it later.

[[folder:Real Life]]

* The human brain largely runs on sugar (among other things). Long periods of intense concentration burn through this sugar at a faster rate, making minor sugar cravings common for people involved in such work.
* Few would question that UsefulNotes/GeorgeWashington was a military genius, and, according to [[Series/GoodEats Alton Brown]], he spent $200 on ice cream over the course of one summer, "and this was a time when $10 could buy you a ''really'' fast horse."
* In his autobiography, Stephen Fry spoke of a long enduring love for sweets, especially as a child.
* Andy Warhol was known for this. He visited pastry shops daily, sometimes buying an entire birthday cake for himself. He often refused more substantive meals, one time explaining to Tom Wolfe, "Oh, I only eat candy."
* According to an interview conducted by the BBC in the 1990s, if StephenHawking were [[http://www.bbc.co.uk/iplayer/episode/p0093xb2/Desert_Island_Discs_Stephen_Hawking/ stranded on a deserted island with a very limited selection of luxuries and amusements]], one of them would be [[http://en.wikipedia.org/wiki/Cr%C3%A8me_br%C3%BBl%C3%A9e creme brulee]].
** This is also referenced in the BBC drama ''Film/{{Hawking}}'' (with Creator/BenedictCumberbatch).
--->"I'm going to eat crème brûlée and a huge number of chocolate truffles, and fight very hard to get you to see how wonderful Wagner is and how Brahms is not so wonderful."
* According to an interview by the New York Times, [[http://www.nytimes.com/2011/07/24/magazine/the-brilliance-of-dwarf-fortress.html?_r=4&pagewanted=all& Tarn Adams]], unstoppable creator of ''VideoGame/DwarfFortress'', hydrates primarily with soda, especially while he's working.
* Julia Medvienekov, the WrenchWench from an untitled R&S production, is a mechanical genius who can frequently be seen eating chocolate.
