Obesity isn’t just limited to one part of the world. Nations everywhere have obese citizens. Some, however, have a far high proportion than others. These nations are categorized as the Most Obese Nations in the World. While some think that the richest and the most developed countries in the world are the most obese, this isn’t always the case. In fact, the United States and the United Kingdom are two of the most economically rich and developed countries in the world. However, they are only ranked 12th and 36th, respectively, when compared to other nations.
There have been multiple nations with small economies that have been classified as the most obese, and the World Health Organization says that the rising costs of healthy food and food scarcity in underdeveloped nations is a contributing factor to obesity.
