NCDs are long-term health conditions like diabetes, heart disease, and cancer. Unlike the flu or COVID-19, they are not contagious (don’t spread from person to person) but are often caused by poor diet, lack of exercise, and tobacco use.

Metabolic diseases involve problems like obesity, high blood pressure, and high blood sugar. While these used to be seen only in adults over 40-50, doctors are now seeing them in school-age children due to lifestyle changes like junk food consumption and lack of play.

The World Obesity Atlas is a major annual report that uses global data to predict how weight-related health problems will grow. The 2026 edition is particularly important because it reveals that countries are failing to meet their goals for reducing obesity.

World Obesity Day is observed every year on March 4. It is organized by the World Obesity Federation to help people achieve and maintain a healthy weight. The report released on this day in 2026 provided the updated figures for India.

Body Mass Index (BMI) is calculated by dividing weight in kilograms by height in meters squared. For children, it is compared against growth charts to determine if they are overweight. A “high BMI” usually indicates that a child has too much body fat.

Chronic diseases like high BP and heart problems were once called “lifestyle diseases of the elderly.” But when children are obese, their bodies start showing these symptoms early. This means they might face serious health crises like heart attacks much earlier in their adult lives.

The three most populous countries (China, India, USA) also lead the world in childhood obesity. While the US has had a high obesity rate for decades, the rapid rise in India and China is a more recent trend linked to economic growth and changing diets.

MASLD (Metabolic dysfunction-Associated Steatotic Liver Disease) is the modern name for fatty liver disease that isn’t caused by alcohol. When children have too much body fat, it starts getting stored in their liver, which can lead to permanent liver damage if not controlled early.

Science shows that babies who are breastfed for at least six months have a lower risk of becoming obese later. Breast milk helps a baby’s body learn to recognize when it is full, whereas bottle-feeding can sometimes lead to overfeeding.

A “sugar levy” is a tax added to the price of sugary drinks and processed foods. The idea is that making unhealthy food more expensive will encourage people to buy healthier options, while the money collected can be used for public health programs.

The World Health Organization (WHO) recommends that children should have at least 60 minutes of physical activity every day. This includes sports, running, or even walking to school. In many Indian cities, the lack of parks and playgrounds makes this very difficult.

India has a “young” population now, which is an economic advantage. But if these young people suffer from chronic diseases like diabetes early in life, they won’t be able to work effectively or contribute to the country’s growth. This empty promise of a healthy workforce is what the author calls being “hollowed out.”
