Ranking the Most and Least Obese Countries in the World

ES Fil FR KO VI

Around the world, over 500 million people face challenges related to obesity. The rate of global obesity has more than doubled since the 1980s, impacting both wealthy and emerging nations. Intriguingly, even in poorer areas like sub-Saharan Africa, it’s possible to find households with both undernourished children and overweight adults.

A Worrying Global Trend

Obesity-related health problems, such as heart diseases, strokes, and Type 2 diabetes, are increasingly prevalent in low to middle-income countries. In fact, nearly 80% of all heart-related conditions now arise in these nations. Countries with a GDP below $5,000, like Pakistan and Nigeria, are especially vulnerable to heart issues stemming from obesity and elevated cholesterol levels.

Several socioeconomic factors contribute to the global surge in obesity. This includes the evolution of national economies, urban expansion, more women joining the workforce (notably, in areas outside Europe, women experience higher obesity rates than men), and the growing accessibility of inexpensive, yet unhealthy, fast food.

Research indicates a unique relationship between a country’s GDP per capita and average BMI:

  • In countries with lower incomes, an increase in GDP is associated with a rise in average BMI.
  • Conversely, in wealthier countries, a higher GDP often corresponds to a decrease in average BMI.
