The story of South Africa in numbers
In 2024, about 31.8% of adults in South Africa were living with obesity — about 1 in 3 adults, according to World Health Organization estimates (the likely range is 28.6% to 35.0%). That is roughly 13.8 million people aged 18 and over.
That is higher than the world average of 16.2%, and ranks 51st highest out of 199 countries. It is above the average for WHO’s Africa region (12.7%).
Back in 1980, the figure was 10.7%. Since then it has gone up by 21.1 percentage points — about 3.0 times the 1980 level. In people, that is a change from about 1.5 million to 13.8 million adults, partly because the population itself changed.
Women are more likely to live with obesity than men: 47.5% compared with 14.5%.
Among children and teenagers aged 5 to 19, 7.8% were living with obesity in 2024, compared with 0.3% in 1980 — around 1.2 million young people.
Obesity is not the only weight problem here: 5.3% of adults are underweight (BMI under 18.5). Health experts call this mix the “double burden” of malnutrition.
For context, 13.9% of adults had diabetes in 2022, 44.8% of adults did not get enough physical activity in 2022 and the food supply provided about 2,694 calories per person per day in 2023. These numbers don’t prove what causes obesity, but they help paint the picture.
South Africa has a national tax on sugar-sweetened drinks, first introduced in 2018, according to the World Bank’s Global SSB Tax Database.
