Obesity can take its toll on a person's health, but it can do the same to Earth's resources.
Here's a list of the 10 most overweight countries in the world in 2005, according to research from the London School of Hygiene Tropical Medicine.
The report was compiled by a team of researchers led by Professor Ian Roberts, who used data from the United Nations and World Health Organization.
The rankings are based on theoretical total energy expenditure and calculated from Food and Agriculture Organization of the United Nations for adults.
