For decades, Italy has been celebrated as the birthplace of the Mediterranean diet — a lifestyle centered on vegetables, legumes, whole grains, olive oil, fish, and fresh ingredients that has long been associated with good health and longevity. Today, however, many health experts say that image no longer reflects reality.
Italy is now facing a growing childhood obesity crisis, particularly in the country’s southern regions. The World Health Organization (WHO) reports that Italian children are among the most overweight in Europe, and communities around Naples have some of the highest childhood overweight rates in the country.
In a recent BBC article, 17-year-old Salvatore knows firsthand how devastating severe obesity can be. Weighing approximately 170 kilograms (375 pounds), even simple daily activities have become difficult. Walking is a struggle, tying his shoes is nearly impossible, and his scooter has repeatedly broken under the strain of his weight.
Doctors say his condition has become so severe that he cannot yet undergo bariatric surgery because the procedure would be too risky. Instead, physicians have prescribed a GLP-1 medication to help reduce his appetite and lower his weight enough to safely undergo surgery in the future.
His story reflects a larger trend that obesity specialists across Italy say they are seeing with increasing frequency. According to bariatric surgeon Dr. Sonja Chiappetta, the age of patients seeking treatment has dropped dramatically over the past decade.
Where severe obesity once primarily affected middle-aged adults, many patients are now teenagers, some as young as 16 years old. The increase has led to greater demand for bariatric procedures, which reduce stomach size and help patients eat less food.
For many young people, however, surgery is only one piece of treatment. Doctors often recommend weight-loss medications, nutrition counseling, and long-term lifestyle changes before surgery becomes an option.
So, what happened to the much-touted Mediterranean Diet? Researchers say Italy’s eating habits have changed substantially over the past several decades.
The traditional Mediterranean diet that once emphasized fresh produce, beans, seafood, whole grains, and olive oil has increasingly been replaced by highly processed foods, oversized portions, sugary drinks, and calorie-dense convenience meals.
Longevity researcher Dr. Valter Longo estimates that only a small percentage of Italians still consistently follow the traditional Mediterranean eating pattern.
Instead, he describes today’s diet as revolving around what he calls the “five Ps” — pizza, pasta, potatoes, protein, and pane, the Italian word for bread.
Even familiar foods have changed. Pizza, once relatively simple, is now commonly topped with fries, sausage, fried foods, and other calorie-rich ingredients that significantly increase its nutritional impact.
Pediatric obesity specialists say one of the biggest challenges is that many parents don’t realize their child has obesity. Children often arrive at medical appointments because of symptoms such as stomach pain, digestive problems, or chronic coughing, while excess weight goes largely unnoticed by their families.
Doctors explain that obesity usually develops gradually through everyday habits rather than one unhealthy meal. Frequent snacking, sugary beverages, highly processed foods, limited fruit and vegetable intake, and oversized portions can slowly contribute to unhealthy weight gain over time.
Many parents believe their children are active enough because they participate in sports or recreational activities. While physical activity is important, experts emphasize that exercise alone often cannot offset poor dietary habits.
Health professionals say cultural attitudes toward body weight can also delay intervention. In some Italian families, a child with rosy cheeks or extra weight may still be viewed as healthy rather than at risk for future medical problems.
Teachers have noticed this disconnect as well. Some educators report concerns about students whose weight may affect their health, yet conversations with families do not always lead to concern or action.
Experts believe schools can play an important role by teaching children about nutrition, hoping those lessons eventually influence family habits at home. Several regions of Italy have launched educational programs aimed at improving children’s nutrition knowledge.
One initiative in Naples will reach more than 17,000 students across dozens of schools while also providing resources for parents. The goal is to encourage healthier eating habits throughout the household rather than focusing solely on the child.
Not every student believes education alone will change behavior. Some teenagers acknowledge they already understand what foods are healthy but continue choosing junk food because it is convenient, appealing, and widely available.
Others believe nutrition education can still make a meaningful difference by helping young people understand the long-term consequences of their choices. Recognizing the complexity of obesity, Italy became the first country in 2025 to pass national legislation officially recognizing obesity as a chronic, progressive, and relapsing disease.
The law reflects a growing understanding that obesity is influenced by many factors beyond willpower, including genetics, biology, environment, food availability, culture, and socioeconomic conditions. This shift encourages healthcare providers to treat obesity as a medical condition requiring comprehensive care instead of simply blaming individuals for their weight.
For teenagers like Salvatore, these interventions represent more than weight loss; they offer the possibility of improved mobility, better health, and the opportunity to participate more fully in everyday life.
As Italy works to reclaim the healthy traditions that once defined its cuisine, healthcare professionals hope a renewed focus on nutrition, education, and comprehensive medical care can help reverse the growing childhood obesity epidemic before another generation is affected.
