The worldwide increase in obesity has been driven by global trade liberalization, economic growth and rapid urbanization. Owing to the scope and complexity of the obesity epidemic, prevention strategies and policies across multiple levels are needed in order to have a measurable effect. Although many putative causes of the obesity epidemic exist, in this Review the effect of globalization on global trends in obesity prevalence is discussed and population-based interventions from several countries are reviewed. The authors make broad policy recommendations for obesity and chronic disease prevention at the global population level.
