India's new urban worry — rising overnutrition
A recent article in Nature that studied the prevalence of Metabolic Dysfunction-Associated Fatty Liver Disease (MAFLD) among IT employees in Hyderabad had alarming findings: 84% of the participants had fatty liver, indicating MAFLD, and 71% were obese. This striking statistic underscores a larger, more insidious public health crisis that is emerging in tandem with the growth of India's urban economy. The underlying drivers are chronic stress, excess salt intake, disrupted sleep patterns, and prolonged sedentary routines, particularly among those in the technology sector. IT companies often tether employees to their desks by offering free kiosks stocked with snacks that fall short of nutritional standards.
Urban India's crisis
India is grappling with a paradoxical nutritional landscape. While undernutrition remains a concern in many regions, overnutrition is now rapidly escalating in urban centres. In 2021, India ranked second globally in overweight and obesity prevalence. The trend is particularly evident in metropolitan IT corridors, where professionals are unwittingly becoming the face of a silent metabolic crisis. India's double burden of malnutrition — rampant undernutrition coexisting with overnutrition — is reflected in its low ranking on the Global Hunger Index.
According to the World Health Organization (WHO), noncommunicable diseases (NCDs) were responsible for 74% of global deaths in 2019 (it was 61% in 2000). These diseases disproportionately affect low- and middle-income countries, including India. WHO's 2024 World Health Statistics warns that NCDs and obesity are increasingly prevalent in the most economically productive segment of society. Without substantial policy interventions, regions such as South-East Asia are unlikely to meet the 2030 Sustainable Development Goal (SDG) targets to reduce premature mortality from NCDs.
In Tamil Nadu, the 2023-24 STEPS Survey paints a stark picture: over 65% of deaths in Chennai are attributable to NCDs. While the NCD cascade of care has shown improvement, there are significant gaps.
Among those receiving treatment for hypertension, only 16% have achieved blood pressure control, and for individuals aged 18-44, this drops to just 9.3%. Among diabetics in the same age group, only 9.8% manage to maintain glycaemic control. The prevalence of overweight and obesity stands at 31.6% and 14.2%, respectively. Additionally, 94.2% of respondents reported inadequate fruit and vegetable consumption, while 24.4% reported insufficient physical activity.
Tamil Nadu's Makkalai Thedi Maruthuvam (MTM) programme, deserves mention for its multisectoral approach to NCD control. From January 2024, 3,79,635 employees have been screened through workplace interventions. The eight-kilometre health walk and the 'Eat Right Challenge' were introduced to encourage behavioural change and nutrition awareness. However, the unchecked growth of fast food outlets in metros remains a formidable obstacle.
The National Family Health Survey-5 shows that obesity steadily rises with age, from 7% among men (15-19 years) to 32% among those aged 40 to 49 years. The prevalence of overweight or obesity rises from 10% in the lowest wealth quintile to 37% in the highest wealth quintile.
The widespread prevalence of overweight and obesity across age groups and income levels underscores that this is not an isolated occupational hazard, but a population-wide health crisis in the making. These trends align closely with data for women. Waist-to-hip ratio (WHR), another NCD risk marker, also increases with age: 46% to 65% in women and 28% to 60% in men (ages 15 to 49). In Tamil Nadu, urban areas report a higher NCD prevalence when compared to rural areas. Overweight or obesity affects 46.1% of urban men and 43.1% of urban women, compared to 35.4% and 31.6%, respectively, in rural areas.
The 18 to 59 age bracket which contributes to Tamil Nadu's majority working force is most vulnerable to early-onset NCDs, also compounded by a growing dependence on ultra-processed foods, alongside other established factors.
A Lancet article (2025) estimates that India's overweight and obese adult population could touch 450 million by 2050 (180 million in 2021). Simultaneously, childhood obesity has surged by 244% over the past three decades and is expected to climb another 121% in the next three.
Focus on manufacturing and marketing
While nutrition awareness at the consumer level is growing, it remains insufficient. The greater responsibility lies with regulators, producers, and policymakers. The market is saturated with ultra-processed foods that offer convenience but little in the way of nourishment. Consumers are frequently left choosing from options that are inherently unhealthy.
To address this, the Eat Right India movement, led by the Food Safety and Standards Authority of India (FSSAI), promotes safe, healthy, and sustainable food. It includes hygiene ratings, certification programmes, and campaigns such as 'Aaj Se Thoda Kam,' which encourages consumers to gradually reduce their intake of fat, sugar, and salt. In partnership with the Indian Council of Medical Research and the National Institute of Nutrition, the FSSAI advocates labelling high-fat, salt, and sugar (HFSS) foods, empowering consumers to make informed choices. In 2022, the FSSAI proposed the Health Star Rating (HSR) aimed at clearer nutritional information on packaged foods. However, the HSR system has sparked debate among medical practitioners and nutrition experts, on its effectiveness.
The Supreme Court of India recently directed an FSSAI-constituted expert committee to submit scientific and technical advice on food safety matters, which includes recommendations on food labelling norms.
However, these efforts must be backed by stricter enforcement and broader multisectoral coordination. Nutritional regulation must extend beyond messaging campaigns to influence what is manufactured, marketed and made available.
The Saudi Arabian model
Saudi Arabia offers a compelling model. As part of its Vision 2030 initiative, the kingdom has embedded NCD prevention into its national policy framework. It enforces calorie labelling in restaurants, imposes a 50% excise tax on sugar-sweetened beverages, and levies a 100% tax on energy drinks. It has instituted sodium limits in processed foods. Saudi Arabia is among the few nations meeting WHO's sodium reduction best practices and recognised for eliminating trans fats. Its success lies in the coherence of its strategy — integrating health, regulatory oversight, industry compliance, and civic engagement.
Meanwhile, India's urban landscape continues to evolve rapidly. Bengaluru, Hyderabad, Pune and Chennai have become economic engines, powered by the technology sector. To accommodate global operations, IT companies are embracing flexible and extended work hours. This transition has resulted in a considerable rise in demand for late-night eateries, cloud kitchens, and food delivery services. However, the vast majority of these offerings are energy-dense, nutrient-poor food products. As a nightlife culture expands in parallel with economic ambitions, so too does the risk of a nutrition-driven public health crisis. While the numbers among IT professionals are eye-catching, the escalating burden of NCDs extends well beyond this sector.
The message is clear: reversing the tide of NCDs demands not just awareness but action. Regulatory reforms, especially those addressing the food industry, are imperative.
Imposing taxes on foods high in sugar and salt — or those failing to meet nutritional standards — could be a logical next step. After all, if there is one thing India has never shied away from, it is introducing new taxes. Why not one that promotes health?

Health Matters newsletter: Smoke trail of India's tobacco burden
On tobacco use in India fuelling a health and economic crisis, an update on the Covid-19 situation, what's killing Indians, the proposed mixing of various systems of medicine, and more By now, everyone knows that tobacco is deeply unhealthy. You could be living under a rock on a remote mountain top, and you would still know that it is unhealthy. Tobacco, the World Health Organization says, is deadly in any form -- it kills more than 8 million people each year, including an estimated 1.3 million non-smokers who are exposed to second-hand smoke. And yet, over 260 million adults in India are users of tobacco, with the use of smokeless forms being about double that of smoked forms. Tobacco accounts for nearly 1.35 million deaths every year in India, even while the country is the second-largest consumer and producer of tobacco globally. This World No Tobacco Day, marked on May 31, we had two experts writingas about what tobacco use does in our country: Dr. Vid Karmarkar writes on the health and economic costs of tobacco and calls for making tobacco products unaffordable, to discourage their use, while Dr. Kinshuk Gupta proposes the use of Artificial Intelligence (AI) as an adjunct to traditional strategies to help step up tobacco cessation efforts. The message is clear: if you are using tobacco, the best gift you can give yourself is to stop now.

Study finds critical medicine shortages for diabetes, hypertension at rural health facilities
New Delhi: A joint survey conducted by the ICMR and the WHO, along with other institutes, has revealed critical medicine shortages for managing diabetes and hypertension at rural health facilities, from sub-centres to sub-district hospitals, across 19 districts in seven states. The study has also found a shortage of specialists at the community health centre (CHC) level and these findings are similar to the rural health statistics report of 2020-21, indicating a shortfall of physicians (82.2 per cent) and surgeons (83.2.9 per cent) at the CHC-level. The study findings, published in the "Indian Journal of Medical Research (IJMR)" suggest that among public health facilities, PHCs, district hospitals and government medical colleges in India are better prepared to manage services for diabetes and hypertension. Across all the facilities, the domain score for equipment was the highest and for medicines, it was the lowest. However, the availability of all medicines was better at tertiary-care facilities (public and private) compared to other levels of public health facilities. A cross-sectional survey of the health facilities was conducted in 19 districts of seven states, which included an assessment of both public and private health facilities. The Indian Public Health Standards and other relevant guidelines were used for the assessment. The service domain score for four domains: equipment, medicine, diagnostics capacity and staff, including the availability of guidelines, and the overall readiness score was calculated following the service availability and readiness assessment manual of the World Health Organisation (WHO). In two phases of data collection, 415 health facilities were covered, of which 75.7 per cent were public and 24 per cent were private. The number of facilities assessed varied across the states. More than half (57.6 per cent) of the health facilities assessed were primary level (33.5 per cent), followed by secondary (33.5 per cent) and tertiary (10 per cent) facilities. More than half (56.3 per cent) of the health facilities were in rural areas. More than three-fourths of all public and private health facilities reported being involved in the follow up of diabetes and hypertension patients. The most common mode of follow ups across all facilities was self-reporting by patients (61.4 to 100 per cent), except for in SCs (29.5 per cent). At SCs, the most common mode of follow up was home visits by health workers (60.4 per cent). The availability of out-referral and in-referral registers across all levels and types of facilities was between 25 and 53.8 per cent and 14 and 61.5 per cent, respectively. "Most public health facilities (from SCs to SDHs) reported stockouts of essential medicines for managing diabetes and hypertension. Out of the 105 SCs assessed, nearly one-third (37/105; 35.2 per cent) reported stockouts of tablet metformin, and nearly less than half (47/105; 44.8 per cent) reported stockouts of tablet amlodipine," the study stated. The median duration of the stockouts for the medicines ranged from one to seven months. The SCs reported more stockouts of essential anti-diabetes and anti-hypertensive medicines compared to any other types of facilities. These medicines were better available at government medical colleges compared to any other levels of public health facilities. The medicine availability score at the primary health centres (PHCs) was just 66 per cent, far below the ideal threshold of 100 per cent. "Our findings suggest that among public health facilities, PHCs, district hospitals and government medical colleges in India are better prepared to manage services for diabetes and hypertension. Across all the facilities, the domain score for equipment was the highest, and for medicines, it was the lowest," the study said. It mentioned the ICMR-India Diabetes Study (ICMR-INDIAB) report's evidence of an NCD epidemic spreading to rural areas in India, in addition to the urban areas, due to changes in the lifestyle. Therefore, improving the preparedness of the SCs will further enhance the primary-care services closer to the homes of people, it stressed. The government has already accelerated its efforts towards strengthening Comprehensive Primary Health Care (CPHC) for achieving Universal Health Care by committing resources and efforts through its flagship Ayushman Bharat Health and Wellness Centres (AB-HWCs). These were recently renamed as Ayushman Arogya Mandirs. "During our assessment, the majority of PHCs (64 per cent) were converted to Health and Wellness Centres (HWCs). This indicates that PHC-HWCs were better prepared to provide comprehensive services compared to SCs, as nearly half of them (52.3 per cent) were transformed into HWCs. However, we found that diagnostic services were less available at district hospitals, indicating that secondary higher-level public health facilities were not fully prepared to manage complications of these two conditions," the study pointed out. Efforts to strengthen diagnostic services are essential for the continuum of care, as there will be in-referrals of patients from peripheral public health facilities to DHs, it said. Lessons from the India Hypertension Control Initiatives (IHCI) project can be adapted to ensure a reliable drug supply and accurate information systems in primary health care facilities, it added.
