HEALTH WATCH

Obesity is no longer a problem confined to affluent societies or a few particular regions of the world. It has quietly, and now quite visibly, evolved into one of the most pressing global health challenges of the 21st century. From bustling metros to remote villages, more people are living with excess weight than ever before — and with it, a rising tide of chronic disease, economic strain, and social consequences that touch almost every household.

A Rapidly Expanding Problem

The scale of the crisis is staggering. The World Health Organisation estimates that worldwide obesity has nearly tripled since 1975. In 2025, more than 1 billion people globally were living with obesity — including hundreds of millions of adults, adolescents, and even young children. For the first time in human history, more people are overweight or obese than underweight in many parts of the world.

Obesity is defined as an abnormal or excessive accumulation of body fat that may impair health, usually measured using the Body Mass Index (BMI). A BMI of 30 or above is typically classified as obesity. But behind this simple number lies a complex web of biology, environment, and behaviour.

The problem is not limited to wealthy countries. Middle-income nations, and increasingly low-income ones, are seeing rapid increases in obesity rates. Urbanisation, changing diets, and more sedentary lifestyles are transforming societies in just a few decades, while our bodies — evolved for scarcity — struggle to adapt to constant abundance.

India’s Double Burden

India is often portrayed as a country battling undernutrition. That picture is only half true today. The country now faces a double burden of malnutrition: underweight and stunting on one side, and overweight and obesity on the other.

According to recent national surveys, the proportion of overweight and obese adults in India has been steadily rising, especially in urban areas. Among children and adolescents, the trend is equally worrying. Changing food habits — more processed foods, sugary drinks, and frequent eating out — combined with reduced physical activity, are reshaping the health profile of the country.

This shift has serious implications. India is already referred to as the “diabetes capital of the world”, and obesity is a major driver of type 2 diabetes, high blood pressure, heart disease, fatty liver disease, certain cancers, and joint problems. As waistlines expand, so does the burden on families and the health system.

Why Are We Gaining So Much Weight?

Obesity is often dismissed as a personal failing, but the reality is far more complicated. At the heart of the problem is an “obesogenic environment” — an environment that promotes weight gain and makes healthy choices more difficult.

Several key factors are at play:

Dietary Changes

Over the past few decades, traditional diets rich in grains, pulses, vegetables, and home-cooked meals have steadily given way to ultra-processed foods. These products are high in sugar, salt, and unhealthy fats, yet aggressively marketed and easily available. Sugary beverages, packaged snacks, fast food, and instant meals offer convenience but at a high health cost.

Physical Inactivity

Technology and urban life have made us more sedentary. Many jobs involve long hours at desks. Children spend more time on screens and less in playgrounds. In crowded cities, walking or cycling may feel unsafe or impractical. The result is fewer calories burned and weaker muscles, setting the stage for weight gain and metabolic problems.

Urban Design and Infrastructure

Cities often lack safe, accessible spaces for walking, running, or playing. Poor public transport, heavy traffic, and pollution discourage outdoor activity. When the built environment makes sitting easier than moving, obesity becomes almost inevitable.

Economic and Social Factors

Ironically, healthy food is frequently more expensive and harder to access than processed alternatives, especially for low-income families. Time-poor parents may rely on quick, packaged options. In many communities, larger body size can even be associated with prosperity and health, complicating the message around weight.

Biology and Genetics

Genetics play a role in how our bodies store fat and respond to food, but genes alone cannot explain the rapid rise in obesity. Rather, they interact with our environment. Human biology is designed to conserve energy — a survival advantage in times of scarcity that becomes a liability when high-calorie food is always available.

More Than a Number on the Scale

Obesity is not just about appearance or body image. It is closely linked with non-communicable diseases (NCDs) such as diabetes, heart disease, stroke, certain cancers, and kidney disease. These conditions develop slowly but have lifelong consequences, often striking people during their most productive years.

The mental health impact is equally serious. People living with obesity frequently face stigma, discrimination, and low self-esteem. Children who are bullied for their weight may withdraw from physical activity, creating a vicious cycle. Adults may avoid seeking medical help for fear of being judged, delaying diagnosis and treatment.

The economic cost is enormous. Health systems are strained by the long-term treatment of obesity-related illnesses. Productivity falls when workers are frequently ill or forced to retire early. For families, medical bills can be devastating, pushing some into debt or poverty.

Rethinking Responsibility: From Individual to Society

Public discussions on obesity often focus on personal responsibility — eating less, moving more, and showing willpower. While individual choices do matter, this narrative overlooks a crucial truth: people make choices within the options they have.

When entire neighbourhoods are flooded with fast-food outlets but lack affordable fruits and vegetables, when advertising relentlessly promotes sugary drinks to children, and when cities are built for cars rather than people, it becomes clear that the problem goes far beyond the individual.

Addressing obesity requires looking beyond the plate and the weighing scale to the structures that shape our daily lives. Governments, food companies, urban planners, schools, and media all have a role to play.

What Needs to Change?

Tackling obesity demands a multi-layered approach:

Healthier Food Environments: Policies that discourage excessive sugar, salt, and unhealthy fats — such as taxes on sugary drinks, clear front-of-pack labelling, and limits on junk food marketing to children — can shift consumption patterns. At the same time, governments must support access to affordable, nutritious food through subsidies, local markets, and support for farmers who grow fruits, vegetables, and pulses.

Active Cities and Schools: Urban planning that prioritises footpaths, cycling lanes, green spaces, and public transport can gently nudge people towards a more active lifestyle. Schools should ensure daily physical education, limit the sale of unhealthy snacks in canteens, and integrate nutrition education into the curriculum.

Stronger Primary Healthcare: Healthcare workers need training and time to identify and manage obesity early, with sensitivity and without stigma. Routine screening for weight, blood pressure, and blood sugar, especially in primary care settings, can help detect problems before they become severe.

Public Awareness and Behaviour Change: Well-designed public campaigns can challenge myths, encourage healthier habits, and normalise seeking help. However, these campaigns must be culturally sensitive and grounded in local realities, not simply copy-pasted from other countries.

Support for Individuals and Families: For many people living with obesity, simple advice to “eat less and exercise more” is not enough. They may need structured weight management programmes, counselling, or medical treatment. Family-based approaches — where the entire household adopts healthier habits — tend to work better than focusing on one person alone.

The Way Forward

Obesity has crept up on the world over several decades. It will not disappear overnight. But the trends are not irreversible. Some countries that have invested in healthier school meals, restricted junk food advertising, improved urban design, and strengthened primary care are beginning to see promising signs.

For India and many other nations, the coming years will be crucial. As populations grow younger and more urban, the choices made today about food systems, city planning, healthcare, and education will decide whether the next generation is healthier or more burdened by chronic disease.

Ultimately, reducing obesity is not just a medical task — it is a social, economic, and moral imperative. It calls for political will, corporate responsibility, and community participation. Most of all, it demands that we move beyond blame to build environments where the healthy choice is also the easy choice.

The world cannot afford to ignore the rising weight of this crisis any longer. The question is not whether we can act, but whether we choose to do so — together, and in time.
