A recent viral Reel on Instagram prompted by a piece in The Times declared that the French are “getting fat because they don’t know what’s in their burgers.” It’s the kind of quote that lands neatly: a jab at the French, a wink at fast food’s global creep, and a tidy explanation for a much more complicated issue—one this gourmand certainly wasn’t about to swallow. In reality, as the latest health surveys show, the picture is far more nuanced.
Obesity is Rising in France
According to the Obepi-Roche epidemiological survey, obesity rates in France have doubled over the past 25 years. Today, 17% of French adults are obese, and nearly half the population is overweight. Specifically amongst 18- to 24-year-olds, (aka Gen Z), rates have quadrupled compared to their predecessors in the 1990s. Childhood obesity is also on the rise, with stark disparities along socioeconomic lines. The trend is impossible to ignore.
The rise is not evenly distributed. Northern and eastern regions such as Hauts-de-France and Grand Est show significantly higher rates, while wealthier regions like Île-de-France remain below average. Socioeconomic status plays an outsized role: working-class professions have nearly double the obesity rates of white-collar professions, and children from disadvantaged backgrounds are far more likely to be overweight. This isn’t just about what’s on a plate, but about where people live, how much time they have, and what food they can afford.
Fast Food’s Rapid Rise
In recent years, France’s relationship with fast food has undergone a dramatic transformation. Once viewed as a distinctly American import, burgers, pizzas, and wraps have now become part of the country’s eating habits. According to new figures, three out of four French people eat fast food at least once a month, and overall consumption has jumped by 30% in just the past five years.
The numbers are reflected in the expansion plans of global chains. McDonald’s, which has already become a big part of the French culinary landscape, is preparing to open 50 additional restaurants nationwide. The goal is clear: to ensure that virtually every household in France will be no more than a short drive away. France is currently McDonald’s second-largest market after the U.S.
But it’s not only McDonald’s. The French fast food market overall is projected to surpass €45 billion by 2028, fueled by younger generations who are more likely to grab a sandwich or kebab on the go than sit down for a multi-course family meal. Despite France’s rich food culture and access to some of the best produce in Europe, many young people choose to eat fast food. According to a BFMTV survey, 59% of 15- to 24-year-olds report going to fast food restaurants, compared to about 37% of the overall population. The traditional sit-down repas is fading in favor of eating fast food on the move.
The Role of Labeling and EU Rules
The Times piece argues that EU regulations let fast food chains obscure ingredient lists, making it harder for consumers to know exactly what they’re eating. There’s some truth to that: while grocery products in France must display nutrition facts and now even carry the color-coded Nutri-Score system (rating food products on a grade of A to E), restaurant meals and fast food items aren’t always held to the same standard.
Still, the idea that French consumers are oblivious is misleading. This is a country where people debate the provenance of cheese, study the terroir of wine, and discuss their dinner plans with the farmers selling seasonal produce at local markets. The real issue isn’t ignorance, but the increasing accessibility, affordability, and marketing of ultraprocessed foods.
But it must be noted that fast food isn’t always the cheapest option in France. A standard McDonald’s or Burger King menu runs between €9 and €12, while budget menus hover around €5–6. By contrast, a fresh sandwich from a boulangerie typically costs €3–7, and a plat du jour at a neighborhood bistro averages €12–15. In other words, a Big Mac meal often costs as much, or more, than a sit-down daily special, and nearly double the price of a bakery sandwich. The convenience of fast food may explain its popularity, but from a strictly financial perspective, traditional French options can be just as affordable, if not cheaper, adding another layer of nuance to the French obesity question.
Public health experts call for stronger nutritional education in schools, stricter regulation of junk food marketing (particularly to children), and policies that expand access to fresh and affordable produce beyond wealthy city centers. France has already taken steps with Nutri-Score labeling and campaigns around eating foods that are moins transformé (less processed), but the system needs reinforcement to work.
A Food Culture that Can Adapt
The French paradox, once shorthand for slim figures sustained by butter, wine, and cheese, is changing. France, like much of the world, is grappling with modern food systems, inequality, and lifestyle changes.
But if there’s one thing French food culture has proven over centuries, it’s an ability to adapt: from military rations to haute cuisine, from village markets to global chains. This challenge will be no different. France doesn’t need 50 more McDonald’s to define its future. What it does need is a balance with policies that support healthier living, and perhaps a cultural nudge that swaps an occasional apéro for a spin class or an outdoor workout in one of Paris’s many parks. Equally social, infinitely better for your health, and still très français.
Because let’s be honest: the French passion for food will never disappear. And that’s exactly why this debate deserves more than a headline about burgers.
