The US adult obesity rate has declined to 37% in 2025, down from a record high of 39.9% in 2022, according to new survey data from Gallup Inc. published on October 28. The drop—equating to approximately 7.6 million fewer obese adults—coincides with a sharp rise in the use of GLP-1 weight loss drugs such as Ozempic and Wegovy.
Gallup’s findings, based on responses from more than 16,000 adults, show the most significant reductions among those aged 40 to 64, the same groups with the highest rates of GLP-1 usage. Obesity was defined using the federal BMI threshold of 30 or higher.
GLP-1 drug use for weight loss has more than doubled since early 2024, rising from 5.8% to 12.4% of adults. While type 2 diabetes diagnoses remain at an all-time high (13.8% of respondents), the report suggests that broader access to these treatments may be contributing to a shift in national health trends. The US still leads many Western nations in obesity, but this marks the first time in over a decade that rates have not increased.
