Argentina passes America in 2030 on adults living with obesity. By 2034 it is 47 in every 100.

Satoria's forecast

Satoria forecast for Argentina: adults living with obesity, in every 100 47.4% of adults in 2034, up from 37.2% in 2024 - clearly higher. 80% range 45.8% to 49.0%.

In 2009, 24 adults in every 100 in Argentina were living with obesity and 35.2 in America. By 2024 Argentina was at 37.2 and America at 41. On our central paths Argentina goes above America in 2030 and reaches 47.4 in every 100 by 2034.

Argentina goes above America in 2030, and America keeps rising.

Our central paths put Argentina at 43.2 adults in every 100 in 2030 against America's 42.7. By 2034 Argentina is at 47.4 and America at 44. Both lines still go up, so this is not America getting better. It is Argentina getting worse faster.

It counts adults against one fixed line, not everybody.

An adult is counted when the body mass index, weight against height, is 30 or more. Children are not in this figure. It is modelled from surveys, so it describes a country, never a person. What it changes for you is what your doctor sees coming: more diabetes, more heart disease, longer waits.

One person in eight in the world is living with obesity.

The World Health Organization says 1 in 8 people worldwide were living with obesity in 2022, and that the adult share has more than doubled since 1990. In 2021 a higher than healthy weight was linked to an estimated 3.7 million deaths from heart disease, diabetes and cancers.

Where does Argentina land in 2034?

Argentina went from 24 adults in every 100 in 2009 to 37.2 in 2024, rising every year. America went from 35.2 to 41 over the same years, less than half as far. Move the slider to where you think our model puts Argentina ten years on.

The ranges overlap, and this was once a rich country problem.

Argentina's published range for 2034 runs from 45.8 to 49 adults in every 100 and America's from 41.6 to 46.4, so they still overlap. The World Health Organization says the rise in middle income countries is what makes this global now.

2030 is the year to check.

Our central paths put Argentina at 43.2 adults in every 100 that year and America at 42.7. That gap is about half a point, so one year either way proves little. What matters is whether Argentina's climb finally slows, and we will record either answer.

What the World Health Organization counted

The World Health Organization's fact sheet of 8 December 2025 says that in 2022, 1 in 8 people in the world were living with obesity, and that worldwide adult obesity has more than doubled since 1990.

The measure here is narrow and worth naming. An adult counts when the body mass index, weight against height, is 30 or more. Children are outside this figure, and the country numbers are modelled from surveys rather than counted person by person.

The fact sheet also makes the point this story turns on: the rise in low and middle income countries is fast making obesity a global problem that was once associated only with high income countries. The health bill is real. In 2021 a higher than healthy body mass index was linked to an estimated 3.7 million deaths from heart disease, diabetes, cancers and other long term illnesses.

Argentina climbed twice as fast as America

In 2009 Argentina had 24.0153 adults in every 100 living with obesity and America 35.2218. By 2024 Argentina was at 37.2003 and America at 40.9585.

Argentina rose in every one of those fifteen measured years, and it rose more than twice as far as America. That is how a gap of eleven points became a gap of under four.

America is not standing still either. Its own share went up in every measured year as well, only more slowly, and it is still the higher of the two today.

What our model says next

On Satoria's central paths Argentina reaches 43.226 adults in every 100 in 2030 against America's 42.6728, so it goes above America that year. The gap that year is about half a point, which is small enough that the crossing could as easily be 2029 or 2031.

By 2034 our central path puts Argentina at 47.3691 and America at 44.0334. Read that pair carefully: both numbers are higher than today. Argentina passing America is Argentina getting worse faster, not America getting better.

Two honest warnings. The published ranges overlap in 2034, Argentina's running from 45.8234 to 48.964 and America's from 41.5977 to 46.4359. And the strength of the model here comes from the shape of the series: these are smooth modelled estimates, so on data held out from fitting and model choice, across 50 country series, its errors were 94% smaller than assuming no change. A smooth series is easy to extend and a real turning point would be a surprise to it.
