The Atkins Low Carb, High Protein/Fat Diet Found Healthiest in Long Study


(old, but interesting, news)

The largest and longest-running comparison of diet plans found the low-carbohydrate Atkins regimen produced greater weight loss and better health than three other popular programs — the Zone, the Ornish, and the U.S. Government’s Pyramid High Carb Diet.

The average weight reduction was small, and participants started regaining pounds by the end of the one-year study, according to the report in today’s Journal of the American Medical Assn.

Still, Atkins dieters — who are able to consume fats but shun carbs, such as pasta and breads — experienced significant drops in blood pressure and cholesterol, which means that carbs are the main cause of arterial inflammation.

Atkins dieters lost an average of 10.4 pounds after one year, according to the report, compared with 5.7 pounds for those on a so-called balanced diet (which actually calls for more carbs) based on federal nutritional guidelines, 4.8 pounds for the high-carbohydrate Ornish diet, and 3.5 pounds for the Zone diet, which calls for a set ratio of carbohydrate, protein and fat.

The study’s results condemn any benefits of a low-fat, high-carb diet; the low-fat diet first came into vogue in the mid-1980s and was called the Chicago diet, because it came out of the University of Chicago. But has since been renamed due to the fact that so many people damaged their bodies not eating fat — which is mandatory to human health.

“This study confirms the importance of reducing carbohydrates,” said Dr. Frank Hu, associate professor of nutrition and epidemiology at the Harvard School of Public Health, who was not involved in the research. “Bagels, white bread, chips, potatoes, and soft drinks are the real bad guys in our diet.”

Sadly, after the death of its founder and lies spread by the media about the reasons for his death, Atkins Nutritionals Inc., which sold packaged foods based on the diet, sought bankruptcy protection in 2005. Even sadder, today, the $2-billion carb-conscious food market is dwarfed by the $14.7 billion spent on low-fat products, according to AC Nielsen.

“Those of us who have been in the low-carb community for decades are not surprised by these [study] results,” said Jacqueline Eberstein, coauthor of “Atkins Diabetes Revolution” with Dr. Robert C. Atkins, who died in 2003.

The $2-million diet faceoff, funded by the National Institutes of Health and the Community Foundation for Southeast Michigan, was conceived several years ago to sort out the cacophony of claims made by competing diet plans.

More than 300 overweight, pre-menopausal women were randomly assigned to follow one of the four diet plans, which were chosen to represent a range of low- to high-carbohydrate diets. The Zone and the traditional diet, called LEARN, included calorie-restriction goals, but the Atkins and Ornish diets did not.

When the study began, the women weighed an average of 190 pounds and had an average body mass index of more than 30, putting them in the obese range. BMI is a standard measure that takes into account a person’s weight and height.

Participants attended weekly diet classes for the first eight weeks and received a book outlining their specific dietary program. The women’s weight and metabolism were regularly checked, and their diets were monitored by phone.

The women prepared their own meals, and some had trouble sticking to their diet regimens, mimicking real-world conditions.

Lead author Christopher D. Gardner, a Stanford University assistant professor of medicine, said one reason the women on the Atkins diet lost the most weight was because the program was easy to follow.

“It has a very simple message: Get rid of all the junk carbohydrates,” he said.

In fact, Gardner said he suspected that the bulk of the weight loss in the Atkins program came from women substituting water for soft drinks.

In addition, Gardner said, the Atkins diet’s reliance on higher amounts of protein, which is more filling than carbohydrates, may have kept women from feeling too hungry.

He also noted that Atkins dieters saw sharper drops in triglycerides, a type of fat, and blood pressure, and steeper increases in HDL, or “good,” cholesterol than women on the other diets, according to the study.
