"Is staying slim good for both your health and the environment ?" Say Phil Edwards and Ian Roberts, researchers at the London School of Hygiene and Tropical Medicine and co-authors of the study. According to their calculations, a slim society, like that of Vietnam, consumes 20% less food and pollutes less than one in which about 40% of people are obese such as the United States. In addition, emissions related to transport are also lower if we maintain a healthy weight, because it is spent less energy in transporting thin people, and because "those who are overweight tend to move less and depend more on the car."
? We must do much more to reverse the global trend towards obesity and recognize that it is a key factor in the battle to reduce emissions and curb climate change, "the scientists conclude.
