The purpose of this paper is to explain the obesity pandemic in Latin America and identify the factors of development contributing to the pandemic. The paper uses the framework of the nutrition transition as presented by Barry Popkin to trace consumption patterns and changes in dietary habits in the region.

The analysis includes ten distinct factors, but concludes that economic growth and urbanization were the most important determinants of a region developing obesity
