American Heart Association Statement on High-Protein, Low-Carbohydrate Diet
Study Presented at Scientific Sessions
Chicago, Nov. 19 -- Media reports about a small study funded by the Robert
C. Atkins Foundation may have created the erroneous impression that the
American Heart Association has revised its dietary guidelines. This is not
the case. This study was released as one of over 3,600 abstracts presented
at the American Heart Association's annual Scientific Sessions, a forum for
the presentation of research pertaining to heart disease and stroke for
scientists and physicians. These scientific abstracts do not represent
official positions or statements of the American Heart Association.
Here are the American Heart Association's concerns with the study:
a.. The study is very small, with only 120 total participants and just 60
on the high-fat, low carbohydrate diet.
b.. This is a short-term study, following participants for just 6 months.
There is no evidence provided by this study that the weight loss produced
could be maintained long term.
c.. There is no evidence provided by the study that the diet is effective
long term in improving health.
d.. A high intake of saturated fats over time raises great concern about
increased cardiovascular risk - the study did not follow participants long
enough to evaluate this.
e.. This study did not actually compare the Atkins diet with the current
AHA dietary recommendations.
"The American Heart Association has dietary guidelines, rather than a rigid
diet. These guidelines, revised in 2000, replaced the Step I and Step II
diet, which emphasized fat restriction. The current guidelines, based on
the best available evidence, emphasize a healthy dietary pattern rich in
fruits, vegetables, whole grains, lean meats, fish and poultry, as well as
low-fat dairy products," says Robert O. Bonow, M.D., the president of the
American Heart Association. "It is important to note that there is no single
'American Heart Association Diet.' Rather there is a set of guidelines
designed to be broad enough to accommodate many different food preferences,
as well as to provide specific guidance for individuals with specific
By way of contrast with this small study, a 12-year Harvard study funded by
the National Heart, Lung and Blood Institute was also reported at this
meeting. This study of 74,000 women showed that those who consumed more
fruits and vegetables were 26 percent less likely to become obese than women
who ate fewer fruits and vegetables over the same time period. "This is a
much more compelling study regarding weight control, because it involved
many more individuals over a much longer period," says Bonow.
"Bottom line, the American Heart Association says that people who want to
lose weight and keep it off need to make lifestyle changes for the long
term - this means regular exercise and a balanced diet," he says. "People
should not change their eating patterns based on one very small, short-term
study. Instead, we hope that the public will continue to rely on the
guidance of organizations such as the American Heart Association which look
at all the very best evidence before formulating recommendations."
