You mean people are overweight because they eat too much?

OH-MY-GOD!

Thank you so much for that unheard of revelation. There I thought that we
could scarf down burgers and fries all day and then walk 15 minutes and
that would solve the problem.

Study blames over-eating, not poor exercise for US obesity
3 days ago

AMSTERDAM (AFP) =97 Over-eating, not a lack of exercise, is to blame for
th=
e
American obesity epidemic, a new study claimed Friday, warning that
physical activity could not fully compensate for excess calories.

"There is no evidence that a marked reduction in physical activity has
been=

a contributor to this epidemic in the United States," study leader Boyd
Swinburn told AFP on the sidelines of an international obesity conference
in Amsterdam, where the research was unveiled.

"The increase in energy intake... virtually explained all of the weight
gain."

Swinburn, a professor at the health faculty of Australia's Deakin
University, said American children had grown on average four kilogrammes
(nine pounds) heavier over the past three decades with adults putting on
an=

extra eight kgs (17 pounds).

The study calculated what Americans should weigh today based on their
current, higher food intake, and comparing this to their actual weight.

If they weighed more than projected, this would suggest a drop in
physical
activity.

In fact, researchers found that American adults weighed less than could
be
expected from their diet, "which means that if anything over that period
of=

time, the adults had been increasing their physical activity, not
decreasing," said Swinburn.

Among children, the tests yielded a 100 percent match, leading
researchers
to conclude that changes in physical activity had had no impact
whatsoever
on America's children growing fatter.

The findings would "probably be similar" for other developed countries,
Swinburn said.

For the US population to return to its leaner, 1970s self, children would
have to cut their intake by about 350 calories a day -- equal to one can
of=

fizzy drink and a small portion of French fries, and adults by about 500
calories -- the equivalent of a Big Mac burger.

Alternatively, children would have to walk for an extra two-and-a-half
hours a day, and adults for nearly two hours, said Swinburn.

"Getting everybody to walk an extra two hours a day is not really a
feasible option for countering the epidemic," he said.

"We need to limit our expectations of what an increase in physical
activity=

can achieve."

Swinburn stressed that the findings did not seek to negate the value of
physical activity for weight control and overall health.

"But if we want to influence the underlying drivers (behind obesity), we
have to have our eye much more on the energy intake side than on the
physical activity side."

In short, Americans must eat less, he said.

The World Health Organisation estimates that in 2005, about 1.6 billion
adults were overweight, of which at least 400 million were obese.

The conference was organised by the European Association for the Study of
Obesity.
