Danish scientists have found a link between increasing levels of
obesity and carbon dioxide in the air. Researchers from the
Glostrup University Hospital studied the weight of both
overweight and slim people over 22 years. They discovered that
thinner people were putting weight for no reason and pinpointed
a correlation between CO2 concentration and weight gain. “The
normal theory is that fat people get fatter because they don’t
move as much as they should,” explains Lars-Georg Hersoug in the
Science Nordic journal. “But the study showed that thin people
also get fatter, and this happened over the whole of the 22-year
period of the study.” The study, in association with the
University of Copenhagen, tested six young men to see how CO2
levels affect their appetite. Half of the men were exposed to
increased amounts of CO2 and the rest in a normal climate. After
seven hours in the assigned room, the men were allowed to eat as
much as they liked. The researchers found that men with greater
levels of CO2 in their
