''Super Size Me'' is a 2004 documentary made by Morgan Spurlock, which follows him as he attempts an experiment to only eat 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.

[[folder: 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. [[SuspiciouslySpecificDenial They claim that these changes were unrelated to the documentary's popularization]].

!!Tropes applying to this documentary are:

* ArtisticLicenseBiology: Morgan admits that he practically never ate out before making the documentary, and that he normally barely even eats meat in his evening meals because his girlfriend is a vegan chef. It's inevitable that somebody who goes from this kind of diet to eating nothing but [=McDonalds=] will have a much more extreme reaction than an average person who eats fast food in moderation. If eating a Super Size Combo made ''everyone'' vomit, do you really think they would keep offering it?
* BigEater: Shows the consequences of such.
** Although they also show Don Gorske, who eats one (or more) Big Macs daily, and is rail-thin. He doesn't touch the french fries or soda though, so he's still ''way'' behind Morgan's intake levels.
* 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: [[Film/FatHead Another documentary film maker]] has accused him of outright fraud in his results; indeed, Morgan has refused to make his food logs public, possibly because even basic math indicates that he could not have followed his own rules and consumed 5,000 calories per day as he claimed. More scientific and less informal studies have found it impossible to replicate his results. It doesn't help that eating 5,000 calories per day of absolutely any sort of food, with limited exercise, is bad for you ''because eating excessive amounts of food while avoiding exercise is what causes all weight gain.'' If [=McDonald's=] food is bad because eating 5,000 calorie's worth of it every day harms your body, then ''all food ever'' is bad.
* DoesThisRemindYouOfAnything: A number of critics compared the vomiting scene to the way heroin addicts often throw up when first using their drug of choice. Spurlock seems to be saying that fast food is just as addictive as heroin.
* 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. In contrast to the film's message, it shows that the Gorske is actually in perfect health because he only eats the Big Macs; he doesn't eat the french fries or drink the soda.
* 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.
* LastSupperSteal: One segment is a painting that shows grotesque caricatures of various fast food mascots set up like "The Last Supper".
* 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 McDonalds. A McDonalds bag is placed to conceal what the interviewee was eating: A McDonalds salad.
* SoundtrackDissonance: The "Blue Danube Waltz". [[spoiler: During scenes of gastric bypass surgery.]]
* SpaceWhaleAesop: The scene of Spurlock vomiting in the parking lot after his first Super-Sized meal. It probably has less to do with [=McDonalds=] being unhealthy, and more with Spurlock forcing himself to eat every single last bite of the meal long past when he was beginning to feel unwell. Who knew that if you force yourself to keep eating when you're already full, and feeling sick to boot, could result in throwing up?
* SuspiciouslySpecificDenial: Meta-Example. sometime after the movie debuted nation wide, Mcdonalds got rid of their Super size option on the menu, stating that it was not this movie that influenced the decision......
* 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 Sperlock goes on a McDonalds diet for a month. It doesn't turn out well for him. (And he was blatantly disregarding the warnings of his physician by doing it.)
