I appreciated your comments on this issue. Thank you for sharing your
research and conclusions. I think you make some very valid comments and
it makes me doubt the conclusions of the study.  However I do have the
sense that we are getting heavier as a group, at least in North America,
and that this does create some very important health issues,
particularly with diabetes and perhaps heart disease and certain joint
problems. Some of these concerns have helped motivate me to bring my own
weight into what I understand to be a safer range (certainly a more
comfortable range). Without going into any sort of prioritizing of what
is really bothering us, is there any basis for my observations and was I
wise to lose weight? In other words, do you think we are becoming
generally heavier and are we more prone to diabetes and other problems
with apparent direct links to obesity?

Obesity Obsession
Friday, March 12, 2004
By Steven Milloy

"Obesity is catching up to tobacco as the leading cause of death in 
America," proclaimed Centers for Disease Control and Prevention chief 
Julie Gerberding this week. "Americans need to understand that 
overweight and obesity are literally killing us," added Health and Human

Services Secretary Tommy Thompson.

While it's not disputed that severe obesity (search) may shorten life, 
the real killer in this case seems to be the CDC's statistical 

The excuse for the desperate health warning is a study in the March 10 
issue of the Journal of the American Medical Association in which the 
CDC claims that poor diet and physical inactivity caused 400,000 deaths 
in 2000. That estimate supposedly represents a 33 percent increase from 
the 1990 estimate and approaches the 435,000 deaths in 2000 supposedly 
attributable to smoking.

Now it's been said that there are two types of statistics ― the 
kind you look up and the kind you make up. CDC's body counts are 
definitely the latter.

The CDC produced its estimates with a statistical ruse called 
"attributable risk" ― the fearmongers' method of choice for 
alarming the public with large body counts. Attributable risk (search) 
could be the poster child for the saying, "garbage in, garbage out."

Without getting lost in the depths of statistical formulas, the key 
components of attributable risk calculations are statistical 
correlations between potential causes and effects, like 
overweight/obesity and premature death. But just because 
overweight/obesity and premature death might have been statistically 
correlated in some studies doesn't mean that overweight/obesity has been

proven to cause premature death.

In the few studies that have reported correlations between 
overweight/obesity and premature death, the vast majority of the 
correlations are small, not statistically significant (that is, they may

be due to chance) and, in short, are unreliable. Reported correlations 
between overweight/obesity with premature death don't start to inspire 
even minimal confidence until the obesity in question is extreme ―

cases where you only need common sense, not statistical hocus-pocus.

Recklessly plugging unreliable statistical correlations into the 
attributable risk formula to produce sensational body counts can only be

described as junk science.

But you don't need to take my word about the folly of the CDC's 

As the New England Journal of Medicine editorialized in 1998, "Although 
some claim that every year 300,000 deaths in the United States are 
caused by obesity, that figure is by no means well established. Not only

is it derived from weak or incomplete data, but it is also called into 
question by the methodologic difficulties of determining which of many 
factors contribute to premature death."

"Calculations of attributable risk are fraught with problems . [and can 
produce] a nonsensical result," noted the Journal. 

And if all this is too technical, just ask yourself this question: Is it

really plausible that the death rate from overweight and obesity has 
increased by 33 percent in the last 10 years?

Let's not forget that despite all the hyperventilating about our health,

the CDC reported last month (with much less fanfare) that U.S. life 
expectancy (search) ― the most objective measure of public health 
― reached an all-time high of 77.4 years in 2002, up from about 
75.2 in 1990.

So what gives? Why does the CDC insist on nagging us about our 
waistlines? Two reasons come to mind.

First, the previously mentioned New England Journal of Medicine 
editorial characterized the obesity obsession as an example of  "a 
tendency to medicalize behavior we do not approve of" ― that is, 
politically incorrect activities like over-eating, not exercising, 
smoking, drinking, and gun ownership.

Next, the public health establishment (search) is simply running out of 
things to do. Preventing and controlling the spread of infectious 
disease, the traditional and primary mission of public health 
professionals, has largely been achieved. The relatively small number of

infectious disease deaths that still occur annually, excluding 
AIDS-related deaths, decreased by 25 percent from 1990 to 2000, 
according to the CDC.

In former President Dwight D. Eisenhower's famous 1961 speech warning us

of a looming military-industrial complex (search), he also said, "The 
prospect of domination of the nation's scholars by Federal employment, 
project allocations, and the power of money is ever present and is 
gravely to be regarded. Yet, in holding scientific research and 
discovery in respect, as we should, we must also be alert to the equal 
and opposite danger that public policy could itself become the captive 
of a scientific-technological elite."

Were Ike witnessing the health nannies' apparent desire to control our 
behavior and bigger budgets, he might warn us of the looming "public 
health-industrial complex."
