The World Obesity Atlas 2026 shows that India, China and the United States account for a large share of the global obesity burden, indicating that the country currently faces malnutrition and childhood obesity.
At the same time, global childhood obesity rates have increased dramatically, from about 4% in 1975 to nearly 20% in recent years. For the first time, the number of obese children globally exceeds those of underweight, marking a major shift in health trends. It also warned that while many countries have taken steps to tackle childhood obesity, progress has not kept pace with the scale of the problem, calling for stronger action on food regulation, physical activity and access to care.
Experts say this is not just a cosmetic problem, but a serious health issue. “Childhood obesity is on the rise due to an imbalance between diet and physical activity, where children consume more calories and exercise less. This is not a cosmetic issue but a disease with long-term risks like diabetes, heart disease and other lifestyle issues,” said Dr. Rajesh Hardgavat, professor, Department of Endocrinology, AIIMS.
This increase is driven by easy access to high-calorie foods, sugary drinks and ultra-processed products, as well as reduced physical activity and increased screen time. Urban lifestyles, a reduction in outdoor play spaces and an increasing reliance on digital devices are further exacerbating this trend.
The trend is also evident among younger children, with overweight increasing even in children under five. Experts warn that the condition often persists into adulthood, increasing long-term risks and increasing the future burden of non-communicable diseases.
