In Battle of the Bulge, This Is No Time to Surrender
Obesity Still Poses Serious Threat to Public Health

Is the obesity epidemic over? Can we call off the fight against
fat and stop worrying about unhealthy eating habits? Many Americans
are now asking such questions—but not because we’ve
actually won the battle of the bulge.
Credit instead a public relations offensive launched by major
players in the food industry. In recent months, these companies
have used intermediary organizations to pour huge sums of money
into newspaper ads and television commercials that dismiss concerns
about obesity as “hype” generated by some vast conspiracy
of government health officials.
As a nutritionist, I have lost patience with such arguments, which
are not supported by the scientific facts. Despite the PR smokescreen,
obesity and high-fat diets continue to pose grave threats to public
health.
To understand how grave, we need only examine the food industry’s
favorite piece of ammunition in this debate—a genuine scientific
disagreement over how many people die from obesity each year. Two
different groups of researchers associated with the Centers for
Disease Control and Prevention have come to very different conclusions
about the death toll associated with obesity.
Such divergent results are not uncommon in science, especially
in population-based studies that use information from a subset
of individuals to draw conclusions about a much larger group. Future
studies will probably clarify this issue. But here’s the
bottom line: Even if the lowest estimate of about 26,000 annual
deaths turns out to be correct, obesity is currently killing more
Americans every year than does AIDS.
And obesity doesn’t have to end a life to change it forever.
Studies have shown that being even moderately overweight can double
the risk of heart disease and triple the risk of diabetes. For
the 30 percent of Americans who are actually clinically obese—that
is, who have a body mass index of 30 or higher—the medical
risks are even more serious.
Hypertension, arthritis, high cholesterol levels, and other obesity-related
health problems can sometimes be managed with medication and treatment,
as the food industry likes to point out. But the cost is staggering.
Between 1987 and 2002, the proportion of private health spending
attributable to obesity increased more than tenfold, according
to a study just published in the journal Health Affairs.
Quality of life also takes a huge hit. If you suffer from obesity-related
arthritis, the chronic pain and impaired mobility imposed by this
condition will probably matter much more to you than whether you
make it all the way to your government-projected life expectancy.
Furthermore, even when unhealthy eating habits don’t make
you obese, they still increase the risk of chronic disease. Researchers
have piled up a mountain of scientific studies showing that high-fat,
meat-centered diets increase the risk of heart disease, diabetes,
and several types of cancer—even in people who are not seriously
overweight.
American consumers have a choice to make. We can keep chowing
down on hotdogs, fried chicken, and ice cream, even as scientists
try to figure out exactly how many of us will die as a result of
our super-sized addictions to high-fat, high-cholesterol foods.
Or we can start making healthy changes. Losing weight can be as
simple as eating more fruits and vegetable and fewer calorie-dense
foods such as cheese and meat, according to recent research at
Pennsylvania State University.
Better diets can have other dramatic results. In a study published
in May in the Annals of Internal Medicine, participants
who ate a low-fat vegetarian diet saw their levels of LDL cholesterol
(the “bad” cholesterol) drop by an average of almost
10 percent in just one month.
The facts are clear: Obesity is a real problem. It’s time
for a real solution.
