Slimming good for the environment, says study

摘要

Staying slim is as important for the planet's health as for our own, a new report reveals. Countries with normal rates of obesity (3.5%) consume almost 20% less food and produce up to one gigatonne fewer greenhouse gases than a population with a 40% obesity rate, concluded the article published in the International Journal of Epidemiology (IJE). Its authors suggest that a higher rate of obesity would mean both an increase in emissions from food production, which today accounts for around a fifth of manmade greenhouse gases, and from transport. They conclude that leaner populations are more likely to walk and cycle, and that cars and planes use less fuel when transporting lighter people.
