Researchers say that although both low fat and low carbohydrate diets
are effective methods of weight loss, the low carbohydrate diet may
raise bad cholesterol. The study includes data from five previous
clinical trials and was published in the February 13 issue of Archives
of Internal Medicine, one of the JAMA/Archives journals.
The Atkins diet made low-carb dieting the rage. Dr. Atkins was a
cardiologist originally looking for a treatment for diabetes when he
stumbled onto the low-carb method for losing weight. He recommended
that his patients avoid carbohydrates because they turn to sugar when
consumed.
Many dieticians saw problems with Atkins approach, which did not
distinguish between good and bad fats. This new research by Alain J.
Nordmann, M.D. of the University Hospital Basel, Switzerland, and his
colleagues found that although the low-carb dieters lowered their
triglycerides, their LDL (bad) cholesterol went up.
The concern over bad-fats has been the cornerstone of the South Beach
Diet. This diet limits carbs, especially sugar, processed flour and
high fructose corn syrup, but the South Beach Diet does distinguish
between good fat and bad fat, promoting fish and chicken over beef.
Recently research from the
Women’s Health
Initiative (WHI) cast doubt on the low fat diet. Researchers
at the cancer Research Center in Seattle found that low
fat diets were no healthier than normal fat diets. They found that low
fat diets did not reduce the risk for breast cancer.
This started the whole debate again concerning low fat diets. Recently
the National Broadcasting Company (NBC) ran a story on the subject.
Correspondent Robert Bazell asked Dr. Walter Willett, a top nutrition
expert at Harvard School of Public Health, some questions.
According to Dr. Willett, olive and other vegetable oils are actually
healthy, while the fat in meat and the so-called “trans fat” in
processed foods cause health risks — especially increased heart
disease. The doctor stresses that the type of fat is very important.
The WHI findings concerned themselves primarily with overall fat. Both
the Zone Diet and the South Beach Diet promote healthier foods. Atkins
deserves credit for his insistence that limiting carbohydrates, but the
newer diets are becoming more particular on both healthy fats and carbs.
