Italy’s child obesity crisis is hitting hardest in the south, where doctors say old food habits and new temptations are reshaping a generation.
Italy’s child obesity crisis is widening, and doctors in the south say the problem is now hitting children at alarming levels. In parts of Campania, more than 40% of eight- and nine-year-olds are overweight, while the town of Ponticelli, near Naples, has gained a grim reputation as one of the world’s child obesity capitals. The country that once sold the Mediterranean diet to the world is now confronting a generation far removed from it.
Seventeen-year-old Salvatore is one of the most severe cases. He weighs 170kg and struggles to walk, tie his shoes or even use his Vespa scooter properly. He is waiting for life-changing surgery at Betania Hospital in Ponticelli, where Dr Sonja Chiappetta has spent 15 years treating patients with serious obesity. She says her patients used to be mostly adults in their fifties, but now teenagers as young as 16 are coming through her door. Salvatore cannot have the operation yet because his weight makes it too dangerous, so doctors have given him a GLP-1 weight-loss injection first.
The rise in obesity sits in sharp contrast with Italy’s long image as the home of healthy eating. The Mediterranean diet, rich in vegetables, legumes, olive oil, whole grains and fish, was built into global fame after US physiologist Ancel Keys and his wife Margaret Keys linked southern Italian eating habits with low rates of heart disease in the 1950s. Today, experts such as Valter Longo of the University of Southern California say the traditional diet has largely disappeared, with only about 10% of Italians still following it. He describes the modern pattern as pizza, pasta, potatoes, protein and pane, the Italian word for bread.
“Italy’s child obesity crisis is hitting hardest in the south, where doctors say old food habits and new temptations are reshaping a generation.”
Doctors say the consequences are visible in clinics and schools alike. Naples paediatrician Roberto Berni Canani says he has treated children as young as two or three who already weigh 25kg. He says many parents do not realize weight is the underlying problem when they bring children in for coughs, stomach pain or diarrhoea. In one example, 10-year-old Francesca eats bread with Nutella for breakfast, sponge cake as a snack, pasta with lentils for lunch and chicken for dinner, while her mother says she will not touch vegetables. Her parents insist she is active through gymnastics and dance and have not seen her weight as an issue.
Teachers and health workers say the habits are reinforced at home, at school and in a culture where a chubby child is often seen as healthy. Schools in old buildings often lack space for proper physical education, and a regional nutrition programme is now reaching more than 17,000 students across 25 schools. Italy also passed a national law in 2025 recognizing obesity as a chronic, progressive and relapsing disease, and Campania is now testing new approaches, including a controversial fast-mimicking diet for 300 overweight adolescents. Some specialists support the idea, while Berni Canani warns that restrictive diets could raise the risk of eating disorders and other harms. The bottom line is that Italy’s child obesity crisis shows how fast a nation’s food culture can change when healthy habits lose ground to convenience and excess.
