According to the World Health Organization, the worldwide prevalence of obesity has more than doubled since 1990, a dramatic shift linked to the phenomenon explained by the nutrition transition theory. Developed by researcher Barry Popkin, this concept describes the dynamic shifts in diet, physical activity levels, and health outcomes that occur as societies undergo profound socioeconomic development and urbanization.

The nutritional transition model, developed by academic Barry Popkin in 1993, outlines five sequential stages of dietary and physical activity changes that accompany economic and demographic shifts in populations. It highlights how societies move from facing challenges of undernutrition and famine to grappling with issues of obesity and chronic diseases.
