Obesity rate is an important public health indicator used to compare the prevalence of obesity across countries and territories. The 2026 obesity rate by country ranking shows the percentage of adults living with obesity and provides separate male and female estimates where available. The data highlights substantial international differences, with many Pacific island populations recording some of the highest rates and several Asian and African countries appearing near the lower end of the ranking. Obesity prevalence can be influenced by diet, physical activity, lifestyle, urbanization, income, food environments, genetics, healthcare access and broader socioeconomic conditions.
