A Nation of Contrasts
India is grappling with a phenomenon known as the "double burden of malnutrition," where significant portions of the population are simultaneously undernourished and overweight. Recent national health data paints a stark picture of this duality. According
to the latest National Family Health Survey (NFHS-6), the share of both underweight and overweight adults is increasing. For women aged 15-49, those with a below-normal Body Mass Index (BMI) rose to 19.7%, while the share considered overweight or obese surged to 30.7%. Men in the same age group reflect a similar trend, with underweight individuals increasing to 19.7% and overweight or obese individuals climbing to 27.3%. This means a shrinking percentage of the population falls within the 'normal' weight range, creating a complex public health challenge.
The Great Urban-Rural Divide
This nutritional imbalance is not uniform across the country; it is sharply divided by geography. Urban centres have become hotspots for obesity, while rural areas continue to struggle with higher rates of undernutrition. In urban India, 42.8% of women are now classified as overweight or obese, a significant jump from previous surveys. In contrast, rural women have a much higher prevalence of being underweight (22.5%). This divide is largely driven by lifestyle and economic shifts. Urbanisation often brings more sedentary work, greater access to high-calorie processed foods, and changing dietary habits. Meanwhile, rural populations, while also seeing a rise in obesity, still face greater food insecurity and limited access to diverse, nutritious diets.
Poverty's Double-Edged Sword
Socio-economic status is a powerful determinant of nutritional outcomes in India. Traditionally, poverty has been directly linked to undernutrition, as lower-income households struggle to afford sufficient and high-quality food. This remains a grim reality, with undernutrition heavily concentrated among the poor. However, a new trend is emerging where economically weaker sections are also becoming vulnerable to overweight and obesity. This is often due to the affordability and accessibility of energy-dense but nutrient-poor processed foods. Wealthier households, on the other hand, show a much higher prevalence of overweight and obesity, highlighting how lifestyle and dietary choices change with economic prosperity.
The 'Nutrition Transition'
At the heart of this issue is India's ongoing "nutrition transition." This refers to a societal shift away from traditional, plant-based diets towards diets higher in fats, sugars, and processed foods. While India has made progress in reducing child stunting and underweight figures over the decades, the rate of improvement has been slow, and child malnutrition remains a serious concern. Simultaneously, the consumption of ultra-processed foods has skyrocketed, contributing to the rapid rise in obesity and related non-communicable diseases like diabetes and heart conditions. This transition means that many households may consume enough calories but lack essential micronutrients, leading to a complex form of malnutrition where individuals can be overweight yet undernourished.
