About This Dataset
Countries by Adult Obesity Rate 2025
Countries ranked by the percentage of adults with a body mass index of 30 or above in 2025, according to WHO Global Health Observatory and NCD Risk Factor Collaboration data. The United States has among the highest obesity rates of any high-income nation — with nearly 42% of American adults classified as obese in 2025, a figure driven by a food environment characterised by ultra-processed food ubiquity, large portion norms, car-dependent urban design that reduces incidental physical activity, and economic inequality that makes calorie-dense processed foods cheaper and more accessible than fresh produce in many communities. The direct healthcare costs of obesity-related conditions including type 2 diabetes, cardiovascular disease, and certain cancers are estimated to exceed $170 billion annually in the United States alone.
Analysis
The top three in Adult Obesity Rate (%) in 2025 are United States (41.9), Mexico (35.4) and Turkey (32.1). The 8 entries in Adult Obesity Rate (%) cover a range of 20.3, from 41.9 down to 21.6. First and second are separated by 6.50, so the leader sits inside the field rather than apart from it. The other 6 are bunched between 21.6 and 32.1 Adult Obesity Rate (%).
