The obesity rate in the U.S. has seen a marked decline over the last three years, as the share of Americans who report using GLP-1 for weight loss skyrockets, according to new data from Gallup.

In the latest report from the Gallup National Health and Well-Being Index, published on Tuesday, 37 percent of American adults are classified as obese, down from the record 39.9 percent reported in 2022. The drop has been gradual: the obesity rate fell to 38.4 percent in 2023, and it fell to 37.5 percent in 2024.

That nearly three-point decline in U.S. obesity over the last three years represents an estimated 7.6 million fewer obese adults, Gallup notes.

Gallup classifies respondents as “obese” if they have a body mass index (BMI) of 30 or higher, consistent with the federal standard for obesity.
