Indians are getting fatter, according to a new government survey, and experts are warning about a health emergency unless the growing obesity problem is tackled on a war footing.
Once considered a problem of the affluent West, obesity has been spreading in recent years in low and middle-income countries - and nowhere is it spreading more rapidly than in India.
Long known as a country of malnourished, underweight people, it has broken into the top five countries in terms of obesity in the past few years.
One estimate in 2016 put 135 million Indians as overweight or obese. That number, health experts say, has been growing rapidly and the country's undernourished population is being replaced by an overweight one.
According to the latest National Family Health Survey (NFHS-5), the most comprehensive household survey of health and social indicators by the government, nearly 23% of men and 24% of women were found to have a body mass index (BMI) of 25 or more - a 4% increase for both genders over 2015-16. The data also shows that 3.4% of children under five are now overweight compared with 2.1% in 2015-16.
"We are in an obesity epidemic in India and globally, and I fear it could soon become a pandemic if we don't address it soon," warns Dr Ravindran Kumeran, a surgeon in the southern city of Chennai (Madras) and founder of the Obesity Foundation of India.
Dr Kumeran blames sedentary lifestyles and the easy availability of cheap, fattening foods as the main reasons why "most of us, particularly in urban India, are now out of shape".
BMI, which is calculated by taking an individual's height and weight into account, is the most accepted measure globally to classify people into "normal", "overweight", "obese" and "morbidly obese". According to the World Health Organization (WHO), a BMI of 25 or above is considered overweight.
But Dr Kumeran and many other health experts believe that for South Asian populations, it needs to be adjusted at least two points lower at each stage because we are prone to "central obesity", which means that we easily put on belly fat, and that's more unhealthy than weight anywhere else on the body. This would mean that an Indian with a BMI of 23 would be overweight.
"If you take 23 as the cut-off point for overweight, I think half the population of India - certainly the urban population - would be overweight," says Dr Kumeran.
According to WHO, too much body fat increases the risk of non-communicable diseases, including 13 types of cancer, type-2 diabetes, heart problems and lung conditions. And last year, obesity accounted for 2.8 million deaths globally.
Dr Pradeep Chowbey, former president of the International Federation for the Surgery of Obesity and Metabolic Disorders (Ifso), says "every 10kg of extra weight reduces life by three years. So, if someone is overweight by 50kg, they might end up losing 15 years of life. We also saw that mortality during Covid was three times higher for overweight and obese patients."

Dr Chowbey, who pioneered bariatric surgery in India 20 years ago - used as a last resort to treat dangerously obese people with a BMI of 40 or above - says obesity's medical impact is well known, but what is less talked about is its psychological and social impact.
"We did a survey of a 1,000 individuals three years back and we found that being overweight impacted sexual health, it led to poor self-image which could impact people's psyche and lead to marital disharmony." Read More...
