The great fallacy: Does ‘Super Size Me’ hold any educational value?
Morgan Spurlock’s 2004 documentary Super Size Me starts with a clip of children singing out the Fast Food Rockers’ ‘Fast Food Song’. “McDonald’s! McDonald’s! Kentucky Fried Chicken and a Pizza Hut!” they sing, before fading out to a quote from McDonald’s founder Ray Kroc that reads, “Look after the customer and the business will take care of itself.”
The irony—we’re supposed to think. The irony of the founder of the biggest fast food chain in the world decidedly putting their customers before their product, knowing that, if people feel well looked after, profits will never be an issue. Super Size Me leaves little room for ambiguities, hitting the subject of obesity hard, saying America has “the biggest people in the world, congratulations!” It even flashes up a flag of America, demonstrating how obesity numbers have doubled since 1980. The culprit? Fast food. More specifically, McDonald’s.
In this story, the big bad is the nation’s heavy reliance on such chains, which corrupt children with bright colours, catchy jingles, targeted products and even trusty mascots who live in the wonderful world of McDonaldland. But out to expose it for the fallacy it is, is Morgan Spurlock, whose venture hinges on the extremes: eating nothing but McDonald’s for 30 days straight, to prove the toll it takes on the body and the mind.
Super Size Me was a global smash upon release. It set a standard for discussions about healthy living and better lifestyles, drawing attention to the harms of excessive fast food eating while presenting a real, lived-in demonstration of what happens when you fall into the traps of an industry that profits from mass consumption. It quickly became a staple in schools and universities as a vital lesson in the dark side of the hospitality industry while shining a light on America’s obesity problem.
Some say it’s also the reason why McDonald’s phased out its Supersize option just six weeks after its release. The company said it was part of a plan to focus on healthier choices; others claim there’s no way there wasn’t some underlying connection to all the points raised over a month earlier by Spurlock. The point is: it did well to scaremonger in the broader discourse about villainous global chains, making people think twice about their own eating habits and how it was affecting them.
But while these are all legitimate touchpoints in the ongoing conversations about food and lifestyle, however dated, does the concept behind Super Size Me actually fall through? When you consider the extremity of Spurlock’s investigation and the potential discrepancies that weren’t then known to the viewer, does the documentary still hold weight, knowing everything we know now?
‘Prompts more questions than answers’
If you’re to take Super Size Me on face value, which, understandably, most people do, it can be seen as a highly educational insight into the dangers of overeating fast food. These are all highly valid points to consider in conversations about modern eating habits and health, and how we should all do better to exercise a good balance between so-called “treats” and more “sensible” options.
Spurlock shows us from the get-go how it’s all going to work, with GP visits taken on camera to give credence to the physical toll his diet will take. We’re let in on how the “game” works: he can choose anything he wants on the menu for the 30 days, but if asked if he wants to Supersize his meal, he has to say yes.
Over the month, we witness Spurlock as his physical and mental health decline (a particularly noteworthy climax occurring when he leans out of his car to vomit), while showing how the impact on his mindset strains almost every corner of his life. Since 2004, however, there has been one obvious criticism about this entire premise: Is it too unrealistic to land in the way it was intended? And does its science fall short for the purpose of entertainment value?
According to pharmacist Deborah Grayson, who runs Practice With Confidence, Super Size Me might have held value once, but it’s a little more complicated now. “There’s no denying that Super Size Me played an important role in getting people talking about food, health, and the influence of the fast-food industry,” Grayson tells Far Out. “At the time, it was quite provocative, and for some viewers, it was likely a wake-up call.”
She continues, “But from a healthcare perspective, particularly with what we now know two decades later, it’s not a film without its issues. The health effects Morgan Spurlock experienced – rapid weight gain, changes in mood, liver stress – are broadly consistent with what we’d expect from a highly processed, calorie-dense diet over time. So yes, in that respect, the film reflects some nutritional truths.”
However, while this might be true, Grayson also argues that “the way it presents them isn’t especially balanced,” adding, “He deliberately chose to overeat, consuming around twice the recommended daily calories, and avoided moderating his intake, which isn’t representative of how most people engage with fast food. One of the biggest concerns is the lack of transparency in his approach.”
The lack of transparency, according to Grayson, centres around the fact that we don’t get insights into the “full picture of his baseline health,” nor are we made “properly aware” of the fact that his choices, like saying yes to the “Supersize” option everytime, were “intentionally extreme”. At the same time, Grayson claims that “there’s also no meaningful involvement of qualified healthcare professionals in the film, and that’s a missed opportunity for proper education.”
This, underscored by the fact that the conversations have long moved past where they were in 2004, makes Grayson feel it’s “dated when compared with today’s public health conversations”, more broadly proving that “the context is more complex than ‘eat this, get sick’.” What about educational institutions using the documentary as a source text for these conversations in 2025? In Grayson’s eyes, it’s okay to refer to, but only “as a starting point, not a source of nutritional truth.”
This way, it can start the necessary conversations about “food marketing, corporate responsibility, and dietary habits,” bolstered by more updated “public health guidance and expert input”. Without that, Grayson highlights, it runs the risk of “reinforcing stigma” or “spreading misconceptions” about health: “Its value now lies more in prompting questions than providing answers. If we want young people to really understand nutrition, we need to be giving them facts, not fear.”
‘A shift in dietary guidance’
It’s clear, therefore, that there are a number of different things at play here: on the one hand, Super Size Me no doubt starts important conversations and draws attention to how fast-food companies manipulate their marketing efforts for monetary gain. However, the intensity of Spurlock’s tactic and the lack of expert insight raise other questions about its credibility, especially now, when conversations have shifted significantly.
Dr Tom Curtis, the Clinical Head of Obesity at Voy, echoes Grayson’s criticisms, focusing on how, when Super Size Me was released, such conversations were in their infancy. “When Super Size Me was released, obtaining clear nutritional information was often challenging, and public understanding of terms like ‘calories’ could be limited,” says Curtis. “Today, while there’s an abundance of information, discerning credible advice from the myriad of online sources presents its own difficulties.”
He continues, “The food industry, which at the time of the film was introducing some salads alongside high-sugar items like the McGriddle, now engages with more nuanced discussions about ‘ultra-processed foods’. However, as the British Dietetic Association (BDA) clarifies, food processing itself isn’t inherently negative; the nutritional quality is the critical factor, and some processed foods can offer benefits – a perspective not fully explored in the film’s primarily anti-fast-food stance.”
He also highlights how the film’s “exposure of aggressive marketing tactics, particularly towards children, and the widespread availability of less healthy food options” are still effective points to consider, as they show “the ongoing challenges of our ‘toxic food environment’.” Still, he argues that “approaches to health and weight management have significantly evolved,” saying that Super Size Me “depicted a reliance on the extensive diet industry and invasive surgical procedures like gastric bypass for severe obesity.”
Concluding, “Today, the development of effective weight-loss medications offers a significant, less invasive therapeutic option for many, reshaping discussions around personal responsibility and medical treatments. This progression accompanies a shift in dietary guidance: from the film’s emphasis on the alarming quantities of fat and sugar consumed by Spurlock, to a greater focus on overall balanced dietary patterns.”
‘Still relevant in educating people’
As a counterpoint during the documentary, we see Spurlock meeting with Big Mac record holder Don Gorske, who eats multiple Big Macs every day, culminating in over 34,128 total during his life so far. The main takeaway here is that, despite his diet, Gorske still seems to maintain a healthy weight and good mental health, showing a different side to Spurlock’s findings that challenge the entire premise.
Still, despite the counterargument and the possibility of Super Size Me losing its educational value over time, some argue it’s still relevant, including Step by Step founder Sarah-Jane Clark, who says that the issues raised haven’t disappeared, making Super Size Me more relevant than ever. “Super Size Me is still relevant in educating people about the health damage that ultra-processed foods can cause and their highly addictive ingredients,” she says.
Continuing, “My hometown, for example, has an obesity rate that is way above the national average. Our town is full of drive-thrus, takeaways and processed food outlets. The correlation is no coincidence. I attended a meeting at our local council entitled ‘a whole systems approach to fighting obesity’, and at this meeting, we discussed the rise in liver damage and “fatty liver disease “in young adults under the age of 25, caused by junk food consumption.”
On the educational value of Super Size Me, Clark concludes, “Unless we educate young people about the damage that these foods that are often seen as ‘treats’, these shocking figures will only increase. So, the film should be shown in schools and colleges as part of the curriculum so young people can make a more informed choice about the harmful chemicals that they consume and the damage that they can cause.”
