Low-Fat Author Leads "Objective"
Study against Low-Carb Diets
this section, we have placed a request for any links to research
and studies proving low-carb diets to be unhealthy.
We finally received a link that sounded like what
we were looking for, but not quite, sent by a
visitor to our web site. What follows is an
interesting investigation by our members into how
financially interested individuals and
organizations can falsify data, to support their
objectives and products.

A team of researchers led by James W.
Anderson, professor of medicine and clinical nutrition in the UK College of Medicine, performed a critical review and computer analysis of eight popular weight-loss diets. He was joined by David Jenkins, professor of medicine and clinical nutrition at the University of Toronto, and Elizabeth Konz, a doctoral candidate in nutrition at UK.
The researchers found that Protein Power and Dr. Atkinsą New Diet Revolution had negative effects --raising cholesterol levels, which have been linked with an increased risk for coronary heart disease.
After reading this article, we thought this is
very significant news. So, we decided to find the
original study or abstract to verify these claims.
The abstract is found here, from the Journal of
the American College of Nutrition (JACN) Volume 19, Number 5, October 2000
Health Advantages and Disadvantages of
Weight-Reducing Diets: A Computer Analysis and
James W. Anderson, MD, FACN, Elizabeth

Eight popular weight-loss diets were
selected (Atkins, Protein Power, Sugar
Busters, Zone, ADA Exchange, High-Fiber
Fitness, Pritikin and Ornish) to be
non-clinically analyzed by means of a computer
to predict their relative benefits/ potential
harm. A summary description, menu plan and
recommended snacks were developed for each diet.
The nutrient composition of each diet was
determined using computer software, and a Food
Pyramid Score was calculated to compare diets.
The Mensink, Hegsted and other formulae were
applied to estimate coronary heart disease risk
Higher fat diets are higher in saturated fats
and cholesterol than current dietary guidelines
and their long-term use would increase serum
cholesterol levels and risk for CHD. Diets
restricted in sugar intake would lower serum
cholesterol levels and long-term risk for CHD;
however, higher carbohydrate, higher fiber,
lower fat diets would have the greatest effect
in decreasing serum cholesterol concentrations
and risk of CHD.
While high fat diets may promote short-term
weight loss, the potential hazards for worsening
risk for progression of atherosclerosis override
the short-term benefits. Individuals derive the
greatest health benefits from diets low in
saturated fat and high in carbohydrate and fiber;
these increase sensitivity to insulin and lower
risk for CHD.
This study is extremely suspicious, and even
unethical for the following reasons:
- Ignoring Clinical Data: The researcher
have opted to not use clinical data. The
methodology, by admission, is based on computer
software that uses specifically written formulas
that measures cholesterol based on subjective
opinions, translated into computer logic by the
software author/programmer. This may be acceptable
in the absence of clinical data, and only as a
hypothesis. However, there
is clinical data, and it is contrary to the
computer simulated results!
- Self-Interest: The leader of this
"study", Dr. Anderson is the author of
of one of the competing plans under this study, High-Fiber
Fitness! Naturally, the computer software
simulation results are in favour of the research
Unfortunately, the public can be fooled by this
"study", just as the writer for the University of
Kentucky was fooled by it. The report/article she wrote, made no mention of this computer software that "simulated" the results, and talked about it is if they were actual
results, not withstanding existing clinical
studies that negate these simulated results!
Sadly, this is a successful method of manipulating science works. And since
many in the medical community and nutritionists cannot find any scientific bases for their
claims against low-carb
diets, they just have to create their own results
to serve their own subjective opinions and/or
