India's obesity crisis could swell to 450 million by 2050

A new study published in The Lancet warns that India’s overweight and obese adult population could reach 450 million by 2050. Childhood obesity has already surged by 244% over the past three decades, signalling a growing public health crisis. The rise is closely linked to rapid urbanisation and changing dietary habits across the country. India’s shift from traditional, nutrient-rich diets to processed, energy-dense foods is a key driver of the problem. This change, known as the 'nutrition transition', has been accelerated by globalisation, rising incomes and urbanisation. Urban food environments, filled with cloud kitchens and late-night eateries, make high-calorie, low-nutrient meals more accessible than ever.

Overnutrition is now a major concern in cities, where obesity rates climb with age, wealth and urban living. The ICMR-NIN Dietary Guidelines for Indians highlight that 70% of caloric intake comes from carbohydrates, while protein and essential micronutrients remain inadequate. This imbalance contributes to a rising burden of non-communicable diseases (NCDs), which now account for 61% of India’s disease burden.

The 18-59 age group, a critical segment of the workforce, is particularly at risk of early-onset NCDs such as diabetes and hypertension. Poor control of these conditions reduces productivity and strains healthcare systems. The crisis is shaped by multiple factors, including workplace culture, food systems, socio-cultural norms and gender disparities, as explained by the socio-ecological model.

In response, India has launched initiatives like Eat Right India, Makkalai Thedi Maruthuvam, POSHAN Abhiyaan and the Public Distribution System to tackle malnutrition in all its forms. Yet, the Global Food Policy Report 2024 estimates that global food system failures cost $12 trillion annually, with India facing escalating healthcare costs due to NCDs. The projected rise in obesity and related diseases poses a significant challenge to India’s health and economic stability. Without effective intervention, the country may see increasing healthcare expenditures and reduced workforce efficiency. Current programmes aim to address the issue, but the scale of the problem demands broader systemic changes.
