Obesity by algorithm: How delivery apps are rewriting childhood
A survey by the Centre for Science and Environment found that 76% of children had access to fast food outlets in their neighbourhoods, and 12% consumed it more than twice a week. Household expenditure data show a steady rise in processed foods and beverages in urban India, even as cereal consumption declines. With over 750 million smartphone users, delivery services bypass both the kitchen and the school gate. The algorithm becomes an invisible decision-maker, shifting taste and habit without ever appearing in the health conversation. India's obesity crisis is no longer hidden in statistics -- it is visible in every classroom, every delivery app notification, and every child’s plate. Childhood in India’s cities is being reshaped not only by screens and social media, but by what arrives at the doorstep wrapped in plastic and cardboard. The daily meal, once a shared ritual anchored in care, is increasingly replaced by algorithm-curated convenience. For children, food now arrives through notifications, discounts, and auto-suggested menus long before hunger even announces itself. What looks like choice is in fact code-driven appetite, and what looks like abundance is often malnutrition in disguise. In the same classroom bench, one child may struggle with chronic fatigue caused by iron deficiency while another exhibits early signs of obesity and metabolic stress. Recent metropolitan school studies indicate that nearly one in three students is already overweight or obese. A 2023 meta-analysis estimated pooled overweight and obesity prevalence among urban school children at 19-23%, with higher rates in private schools. By 2030, India is projected to have more than 27 million children and adolescents living with obesity, accounting for roughly 11% of the global burden. At the same time, National Family Health Survey-5 data reveal that among girls aged 15-19, anaemia prevalence exceeds 59%, while among adolescent boys stands it stands at nearly 31%. This coexistence reflects the double burden of malnutrition -- a generation both overfed and undernourished, driven not by scarcity but by calorie-dense, nutrient-poor diets. How the algorithm shapes appetite: Food delivery platforms have become powerful actors in the urban food system. Their algorithms are not neutral -- they amplify foods that maximise profit, often those high in sugar, salt and unhealthy fats. Through visuals, time-bound deals and personalised nudges, children are repeatedly steered toward the same narrow spectrum of ultra-processed food. A survey by the Centre for Science and Environment found that 76% of children had access to fast food outlets in their neighbourhoods, and 12% consumed it more than twice a week. Household expenditure data show a steady rise in processed foods and beverages in urban India, even as cereal consumption declines. With over 750 million smartphone users, delivery services bypass both the kitchen and the school gate. The algorithm becomes an invisible decision-maker, shifting taste and habit without ever appearing in the health conversation. Overlaying this landscape is the rise of health washing. Foods marketed as “baked,” “multigrain,” or “protein-rich” often remain nutritionally poor, but these labels soften perception. Delivery platforms now curate alleged healthy menus that serve more as reassurance than reform. Parents attempting to make better decisions find themselves navigating a marketplace engineered to blur the distinction between nutrition and promotion. India generates over 3.5 million tonnes of plastic waste annually, much of it from food packaging. Delivery meals commonly involve multiple layers of non-recyclable waste -- plastic trays, foam insulation, aluminium foil, sachets and disposable cutlery. Between 2016-17 and 2020-21, reported plastic waste generation increased by more than 40%, with metropolitan cities contributing disproportionately. Each meal delivered adds to landfill pressure, clogged drains and carbon emissions. What begins as dietary convenience multiplies into environmental stress, worsening urban pollution, groundwater contamination and ecosystem degradation. Children’s dietary shifts thus feed both a health crisis and an ecological one.
