The study concludes that being overweight or obese “should be recognized as an environmental problem” because of its contribution to climate change from additional food and transport emissions.

Phil Edwards and Ian Roberts of the London School of Hygiene & Tropical Medicine found that a lean population, such as the Vietnamese, consume about 20 percent less food and produce fewer greenhouse gases than a population in a country like the United States, where about 40 percent of people are obese.

The authors also found that transport emissions will be significantly less in countries with healthy average body weights because it takes less energy to transport slim people.


“Humankind — be it Australian, Argentinian, Belgian or Canadian — is getting steadily fatter,” the London researchers say in their study. “We need to be doing a lot more to reverse the global trend towards fatness, and recognize it as a key factor in the battle to reduce emissions and slow climate change.”
