The story of Sri Lanka in numbers
In 2024, about 11.2% of adults in Sri Lanka were living with obesity — about 1 in 9 adults, according to World Health Organization estimates (the likely range is 9.9% to 12.7%). That is roughly 1.9 million people aged 18 and over.
That is lower than the world average of 16.2%, and ranks 169th highest out of 199 countries. It is above the average for WHO’s South-East Asia region (8.3%).
Back in 1980, the figure was 0.5%. Since then it has gone up by 10.7 percentage points — about 22.4 times the 1980 level. In people, that is a change from about 42 thousand to 1.9 million adults, partly because the population itself changed.
Women are more likely to live with obesity than men: 15.0% compared with 7.1%.
Among children and teenagers aged 5 to 19, 4.2% were living with obesity in 2024, compared with 0.3% in 1980 — around 222 thousand young people.
Obesity is not the only weight problem here: 11.9% of adults are underweight (BMI under 18.5). Health experts call this mix the “double burden” of malnutrition.
For context, 25.1% of adults had diabetes in 2022, 37.2% of adults did not get enough physical activity in 2022 and the food supply provided about 2,675 calories per person per day in 2023. These numbers don’t prove what causes obesity, but they help paint the picture.
Sri Lanka has a national tax on sugar-sweetened drinks, first introduced in 2018, according to the World Bank’s Global SSB Tax Database.
