-->-- '''Morgan Spurlock'''

''Super Size Me'' is a 2004 documentary made by Morgan Spurlock, which follows him as he attempts an experiment to only eat UsefulNotes/McDonalds food for 30 straight days.

This experiment is used as a framing sequence as Morgan takes a cross-country look at the various facets of fast-food culture in the United States, including its effects on the human body over a sustained period of time, diehard fast-food fans, the use of processed food in the American public school system, and the impact of fast-food on American society and business.

[[AC:The rules of Morgan's experiment are:]]
# For 30 days, he can't eat or drink anything that isn't on a [=McDonald's=] menu.[[hottip:*:Including water and soft drinks.]]
# He must eat three meals a day -- breakfast, lunch, and dinner.
# He must consume everything on the menu at least once.
# If a cashier asks Morgan if he wants to "super size" his meal, he must agree.
# He will attempt to walk about as much as (or rather, not substantially more than) a typical U.S citizen, based on a suggested figure of 5,000 steps per day.
# He must consume everything on his plate.

As a result, Spurlock ends up suffering from various health problems, such as lethargy, depression, headaches, a reduced sex drive, heart palpitations and weight gain. However, Spurlock completes the experiment, and concludes that fast-food can have incredibly damaging effects on the human body if eaten consistently and constantly, as well as stating that the experiment was an extreme case.

The film was generally well-received, and earned over $11 million dollars (against a $65,000 budget) at the box office. Soon after this documentary was released, [=McDonald's=] stopped offering the super-size option for their meals and introduced a 'Go Fit!' meal. Contrary to the popular belief that [=McDonald's=] instituted these changes to save face after the movie came out, they actually started phasing out the super-size in early 2004 (the film was released in May of that year) and had already been market-testing healthy alternatives. Unless [[UsefulNotes/ConspiracyTheories McDonald's was spying on Spurlock]] while he was filming the documentary, the release of this film was entirely coincidental.

''Super Size Me'' inspired a great deal of criticism from the scientific community, including several counter-documentaries (such as ''Film/FatHead'') which pointed out serious flaws with Spurlock's film.

!!Tropes applying to this documentary are:

* BigBad: (literally) [=McDonald's=]. Though other companies are criticized, the Golden Arches take the spotlight in the blame of the obesity epidemic.
* BigEater: Shows the consequences of such.
* DeepFriedWhatever: In an extra feature on the DVD release, Spurlock visits a fish and chip shop that also experiments with deep-frying candy bars. Since Morgan is still on his [=McDonald's=]-only diet while they visit, he defers to his cameraman.
* DocumentaryOfLies:
** The idea of showing the food to be fattening is undermined by the imprecise methods. Spurlock's doctor states in the film he was eating about 5000 Calories a day (twice what he should be), but there's no exact log of the items and quantities he was eating. There's no way to tell how many of those Calories came from oversized portions in [=McDonald's=] available meals or ordering too many of them. If he was following the rules as stated it shouldn't be anywhere near that.
** Spurlock's physiological reaction to the diet--vomiting, headaches, mood swings, decreased sex drive, etc.--were likely as bad as they were because he had been vegan for years before started the experiment. Regardless of prior health, anyone going from that kind of diet to eating exclusively [=McDonald's=] is going to have a more extreme reaction than someone already accustomed to meat and fried foods. A [[http://www.nationalreview.com/article/214753/soso-so-good-interview number]] [[http://www.al.com/entertainment/index.ssf/2015/08/meet_the_science_teacher_who_l.html of]] [[https://www.sott.net/article/126285-Supersize-me-revisited-under-lab-conditions people]] [[FatHead have tried]] and failed to replicate the results of his experiment, suggesting that his weight gain and visceral reactions were simply the result of an abrupt lifestyle change.
** The liver damage that Spurlock's diet allegedly gave him seems a ''lot'' less damning after Spurlock later revealed that he's had very lengthy struggle with alcoholism since his teenage years.
* DoesThisRemindYouOfAnything: A number of critics compared the vomiting scene to the way heroin addicts often throw up when using their drug of choice. Spurlock seems to be saying that fast food is just as addictive as heroin.
* EverythingIsBigInTexas: Present and discussed when Morgan goes to Texas, the fattest state of the Union in absolute numbers and the one where he is offered a "Super size" more often.
* FanBoy: Spurlock visits renowned Big Mac fanboy Don Gorske, who achieved notoriety for eating at least one Big Mac a day for well over a decade. Unlike Spurlock during the film, Gorske's health has been unaffected because he only eats the Big Macs; he doesn't eat the french fries or drink the soda.
* FastFoodNation: Morgan Spurlock's documentary paints America as obsessed with [=McDonald's=] and the titular super-size option, to the point of health risk without care by the corporation.
* GranolaGirl: Spurlock's girlfriend.
* IndestructibleEdible: One of the DVD extras had him put [=McDonald=]'s food products in jars and see how long it took them to go bad. The fish sandwich was the first to go, lasting only a couple of days, the various burgers lasted about two weeks before becoming moldy. The french fries on the other hand were completely unchanged (at least visibly) after ''ten weeks'', at which point they were accidentally thrown out by an intern.[[note]]It should be noted that this could be explained not because or preservatives or anything scary, but because french fries are thin enough to not retain any water, and bacteria, mold, and mildew can't grow without water; similar to how a slice of bread in a plastic bag will grow mold but one left sitting on the counter will merely dry out and get stale.[[/note]]
* LastSupperSteal: One segment is a painting that shows grotesque caricatures of various fast food mascots set up like ''Art/TheLastSupper''.
* {{Leitmotif}}: [[https://www.youtube.com/watch?v=ryynfuEkZeI Takes after the film's title too.]]
* NonmammalMammaries: One of segments explained that [=McNuggets=] were originally made from chickens with larger-than-normal-breasts. This was demonstrated with an animated chicken with pendulous breasts so big that it had to walk with a cane.
* SceneryCensor: At one point, Morgan is interviewing someone while they have lunch at [=McDonald's=]. A [=McDonald's=] bag is placed to conceal what the interviewee was eating: A [=McDonald's=] salad.
* ShoutOut: [[WesternAnimation/LooneyTunes Bugs Bunny and Sylvester]] make cameos in the parody art of "The Last Supper".
* SoundtrackDissonance: The "Blue Danube Waltz". [[spoiler: During scenes of gastric bypass surgery.]]
* ThinkOfTheChildren: One of Spurlock's interview subjects is an attorney building a case against the fast food industry. The attorney explains that his particular focus on [=McDonald's=] is because of their focus on children: the [=PlayPlace=] playgrounds, birthday parties, the Happy Meal, the advertising mascot Ronald [=McDonald=]...
* VomitIndiscretionShot: Spurlock force-feeds himself a Super-Sized meal and almost immediately pukes it back up again.
* AWeightyAesop: This is the point of the film, where Morgan Spurlock goes on a [=McDonald's=] diet for a month. It doesn't turn out well for him.
