I just finished participating in a
conference call with with Dr. Michael Dansinger, MD and Dr. James
Hill, PhD. as they debated the findings of the latest Atkins study
and the merits of a low-carb diet. A slew of low carb bloggers and
medical practitioners made up the panel, including big names like
Jimmy Moore, Dr. Mary Vernon, Regina Wilshire, Dr. Eric Westman, and
Dana Carpender.
The call began with the host, Jason
Rosenberg of RevolutionHealth.com, who introduced Dr. Dansinger and
Dr. Hall. Dr. Dansinger then presented the findings of the study, which was conducted at Stanford University by Dr. Christopher Gardner. (Check out the study in the Journal of the American Medical Association.)
311 overweight women were randomly
assigned to one of the popular diets: Atkins, the Zone, Learn (which
follows the American government's dietary recommendations) or the
Ornish diet.
Subjects were coached on the respective
diets for two months, attending a class every two weeks which was
based on the book. After the two month teaching period, subjects were
allowed to follow the diets unsupervised.
After one year, the 77 women from the
Atkins group lost an average of 10lbs – twice as much as those on
the low fat Learn and Ornish diets. Women on the Zone lost an average
of 3.5lb.
Along with the most success in terms of
weight loss, the Atkins dieters also showed a greater improvement in
heart disease risk factors, with larger reductions in body mass
index, triglycerides and blood pressure.
After Dr. Dansinger's description of
the study, Dr. Hall of the University of Colorado offered his own
analysis. He agreed wholeheartedly that weight loss is greater when
following a low carb approach at the six month mark, but found that
the differences after one year were not statistically significant.
His main point was that while Atkins has been repeatedly shown to be
the best diet for weight loss, all of the diets studied have similar
rates of failure after one year. At the one year mark, most of the
people, regardless of dietary approach, are regaining the weight they
lost. Dr. Hall believes we need to move away from studies of weight
loss and figure out how people can keep the weight off. He also
mentioned that his involvement with the National Weight Loss Control
Registry leads him to believe that the best predictor of successfully
maintaining weight loss is a person's level of physical activity.
I was glad to hear from all the medical
professional on the call an emphasis on how consistent their findings
have been regarding the intake of saturated fat and associated
positive lipid profiles. In plain English: eating saturated fat (in
the absence of carbohydrates) will not make your cholesterol
skyrocket, or your bottom get bigger.
But hey, this butter-lovin',
pork-guzzlin', steak-devotee already knew that. I did find the
“maintenance problem” an interesting one though. My question to
the panel was: what if the social climate wasn't so hostile to
low-carbing – would people have an easier time sticking with the
diet long-term?
The doctors on the call agreed that the
majority of mainstream practitioners would most likely not recommend
a low carb diet to the patients, and a good chunk of them would
actually advise against it. Bear in mind that this recommendation is
completely without scientific basis. One thing everyone on the call
agreed upon was the urgent need to teach other physicians the science
behind low carb so that they aren't giving misinformation.
I think this is a huge problem. I
haven't kicked up much of a fuss about it here, but I've had worried
friends and relatives pass on their doctor's dire warnings about my
diet. I've had people rolling their eyes even at the mention of low
carb, and groans at the amount of fat I eat as though I'm downing
plates of arsenic.
I get irritated going to restaurants
and paying money for sides I won't eat. I'm frustrated by the myriad
grocery options for the low fat folks, and the idiotic “heart
healthy” labels slapped on sugary cereals.
The combination of uneducated doctors
and nutritionists giving out faulty advice and the anti-low-carb
mainstream media creates a culture very hostile to low carbers. I
firmly believe that if the public health message about sugar turning
into fat becomes more widespread, we'll have an easier time socially
and be even more likely to stick to this delicious way of eating.
When I point this point to Dr. Hall, he
countered by saying that Atkins had its spot in the limelight in
2003. If my hypothesis is correct, low carb should have taken off
like a rocket back then and never come down. Why, he asked, didn't
everyone stick to it when it was all the rage?
Dana Carpender made some good points in
answer to this question. First, a lot of people who said they were
doing low carb were really just relying on the low carb junk food
that came out at the time. Atkins-certified products with white flour
and high fructose corn syrup...I believe mention was made of the good
Dr. A turning in his grave at the thought of this. Then there are the
fad dieters to take into account, those who don't see dieting as a
permanent change but skip from trendy plan to trendier plan. The
fickleness of the media, who wanted the “next best thing”, and
the untimely and ill-reported death of Dr. Atkins were Dana's final
reasons for the decreasing popularity of Atkins.
I'd also like to add that the very
“fad” aspect of 2003 Atkins did not help foster the kind of
environment I'm talking about. Popular perception of Atkins at the
time was not that we'd found a thrilling new approach to healthy
eating, it was “Did you hear about this crazy diet where you can
eat pounds of bacon and still lose weight?”
If someone states that they're trying
to watch their calories, or keeping an eye on their fat intake, or
cutting out meat and dairy, nobody jumps all over them with
hysterical predictions of failure or diseases diagnoses. All low
carbers are asking for is that the low carb approach be recommended
as an option alongside low fat, since the medical safety of Atkins
has been proven by this and many other studies. Oh yeah, and that the
American Heart Association and the American Diabetes Association read
some of the latest research for a change.
