Science & Technology»Staying slim 'could save the world'
»Monday, November 30,2009
According to research by the London School of Hygiene & Tropical Medicine, leaner populations consume around 20% less food and produce less greenhouse gases than countries where 40% of people are obese.
Published in the International Journal of Epidemiology, the study also claimed that transport-related emissions would be lower in leaner countries, with a slim population of one billion people generating around 1,000 million tonnes less carbon than a fat equivalent.
Authors Phil Edwards and Ian Roberts said the report demonstrates how more should be done to reverse the rising average body mass index (BMI), which is used by doctors to analyse if people are a healthy weight.
It is hoped the introduction of such measures across the world could play a major part in the battle against climate change.
"When it comes to food consumption, moving about in a heavy body is like driving around in a gas guzzler," they explained.
"The heavier our bodies become the harder and more unpleasant it is to move about in them and the more dependent we become on our cars."
