Depending on who is doing the eating, living off nothing but burgers and McNuggets has wildly different outcomes.
Just when McDonald’s thought it may have found its very own Jared Fogle—the “Subway Guy”—to prove you can go on a steady diet of Mickey D’s and still be healthy, here comes news that eating too many Big Macs may be more like declaring war on the good bacteria in your gut.
Ever since the phenomenon of the popular documentary Super Size Me more than a decade ago, plenty of Internet memes surrounding the question of “What crazy things happen to your body when you eat a ton of McDonald’s?” have been spawned. The sheer ubiquity of the once indomitable fast-food chain swiftly made it the lumbering target for everything that’s gone wrong with how we eat, and thus, the prime culprit behind Americans’ ever-expanding waistlines and related health issues.
But last year, a high school science teacher from Iowa became a viral sensation by touting an all-McDonald’s diet that allowed him to shed more than 60 pounds in six months. It started as a class project: John Cisna challenged his students to come up with a diet consisting entirely of food from McDonald’s yet still within the federal government’s 2,000-calorie-a-day guideline for adults, and he gamely became the class guinea pig.
