India spent decades fighting hunger. Now it is fighting the opposite problem.

The latest National Family Health Survey (NFHS-6), released in 2026, shows close to a third of Indian women are now overweight or obese, up from a quarter just four years earlier. One in five Indian men has high blood sugar. And the Economic Survey 2025-26 warns that the number of obese children could jump from 3.3 crore in 2020 to 8.3 crore by 2035. Meanwhile, Indians are buying more packaged and ultra-processed food than ever.

The link is not a coincidence. What Indians eat has changed faster than how Indian bodies cope with it, and the result is showing up in clinics, in policy and, increasingly, in healthtech.

Where India stands

NFHS-6 surveyed about 6.8 lakh households across 715 districts in 2023 to 2024. In just four years, the numbers that matter most moved the wrong way:

That is a jump of about 4 to 7 percentage points in four years, across a population of over 140 crore people.

For scale, the ICMR-INDIAB study, the largest count so far, estimated about 10.1 crore Indians with diabetes, 13.6 crore with prediabetes and 35.1 crore with excess belly fat.

What changed on the Indian plate

The Economic Survey 2025-26, presented in January 2026, put numbers on the shift. Sales of ultra-processed food in India grew by more than 150% between 2009 and 2023. Retail sales rose about 40-fold, from roughly $0.9 billion in 2006 to nearly $38 billion in 2019. Over the same period, obesity rates nearly doubled among both men and women.

Three things drove it:

• Price and reach. A ₹10 pack of biscuits or chips is cheaper than a fresh meal and available in every kirana store, including in villages.
• Busier lives. More working couples, longer commutes and food delivery apps have made ready-to-eat food the default.
• Aggressive marketing. Packaged snacks are heavily marketed to children, often with claims like "healthy" or "made with real fruit" that hide the sugar and salt inside.

Add a traditional diet already heavy in white rice, refined flour and sugar, and much less physical activity than a generation ago. The result is a population eating more calories of worse quality, and burning fewer.

The policy response

For years, India's food rules focused on safety and hygiene, not on what packaged food does to health over time. That is starting to change.

• The Economic Survey goes further. The 2025-26 survey recommends putting ultra-processed food in the highest GST slab, adding surcharges on foods high in sugar, salt and fat, and exploring a ban on ultra-processed food ads from 6 am to 11 pm across all media.
• Warning labels on the way. Under pressure from the Supreme Court, FSSAI proposed front-of-pack warning labels in August 2026: a red hexagon reading "High Sugar", "High Salt" or "High Fat" on packaged foods that cross ICMR-NIN thresholds. The court called the earlier voluntary timeline a waste of time and linked clear labels to the right to health.
• Sugar boards in schools. CBSE has asked its 24,000 plus affiliated schools to put up "sugar boards" that show how much sugar is in common snacks and drinks.
• Eat Right India. FSSAI's long-running campaign to cut salt, sugar and fat intake, alongside the earlier push to remove industrial trans fats from the food supply.

Critics say the proposed labels are too small and the rollout too slow. But the direction is clear: the government now treats diet as a public health issue, not just a personal choice.

What other countries did

India is not the first country to face this. Three countries took on packaged food and sugar head-on, and their results show what actually works.

Chile: labels, ad limits and school bans

In 2016, Chile passed one of the world's strictest food laws. Packaged foods high in sugar, salt, fat or calories carry black warning labels on the front of the pack. Junk food ads aimed at children are restricted, and schools cannot sell those products. A study in PLoS Medicine found household purchases of sugary drinks fell 23.7% after the law took effect.

Mexico: a soda tax

In January 2014, Mexico added a tax of 1 peso per litre on sugary drinks, roughly a 10% price rise. A study in the BMJ found purchases fell 6% in the first year and 12% by December 2014. The biggest drop came from low-income households, where purchases fell 17% by the end of the year.

UK: tax the sugar, not the drink

The UK's Soft Drinks Industry Levy, introduced in 2018, taxed companies based on how much sugar their drinks contained. Instead of paying, most companies cut the sugar. By 2024, average sugar in UK soft drinks had fallen 47.4% and total sugar sold in them had fallen 39.8%.

What India can learn

• Labels work best with teeth. Chile's labels worked because they came with ad limits and school bans, not on their own. India's proposed labels are a start, but critics say they are small and phased in slowly.
• Price changes behaviour fastest for the poor. Mexico's tax hit hardest among low-income families, the same group in India that is most exposed to cheap packaged snacks.
• A smart tax changes the product, not just the price. The UK levy pushed companies to reformulate. A sugar-linked GST slab, as the Economic Survey suggests, could do the same for Indian brands.

The bottom line

India's lifestyle disease problem is a food problem first. Cheap, heavily marketed, ultra-processed food has reached every corner of the country, and the bill is arriving as diabetes, belly fat and high blood pressure.

Policy is finally moving, with warning labels, school sugar boards and pressure from the Supreme Court. But labels alone will not reverse a crore-scale health crisis. The bigger opportunity lies in helping Indians manage what they eat, track what it does to them and stay on treatment for years. That is a job built for healthtech, and the market for it is only getting bigger.
