Food energy intake and obesity

Food energy intake and obesity percentage by countries

x axis: average daily dietary energy consumption per capita (2005–2007) in kilocalories;
y axis: percentage of obese population; bubble size: population.

One-sentence Synopsis:

The increasing availability of energy-dense foods leads to an increase in obesity worldwide.

Data sources:


Obesity is one of the greatest public health challenges of the 21st century. (WHO


  • dramatic increase of obesity rates in countries that are undergoing rapid economical development;
  • rural workers moving to urban areas perform less physical labor;
  • traditional low-fat and low-protein diets that include local goods are supplanted by processed foods that are high in fat and sugar;
  • access to food with high caloric value but little nutritional value spreads.

Possible explanation for non-linearity of correlation:

  • unequal distribution of energy consumption within countries due to social and economic inequality;
  • differences in physical activity (labour, sport).
