Despite skepticism
among many in the health care community, the high-fat, low-carbohydrate
Atkins diet has yielded positive results in recent studies.
Rather than raising
cholesterol, as some suspected, the Atkins diet was found
to improve cholesterol levels. Likewise, study participants
lost weight while following the diet.
One recent study
compared the Atkins diet to the American Heart Association’s
Step 1 diet, which uses a low-fat approach. A group of 120
overweight volunteers were randomly assigned to one of the
two diets. Those on the Atkins diet received about 60 percent
of their calories from fat while limiting their carbohydrate
intake to less than 20 grams per day. After six months, the
people following the Atkins diet had lost 31 pounds, while
those on the AHA diet had lost 20 pounds. Also, people were
more likely to stick with the Atkins diet than the AHA diet.
In terms of cholesterol,
HDL (good) cholesterol increased 11 percent in those on the
Atkins diet while that of the AHA participants remained unchanged.
LDL (bad) cholesterol did not change significantly in either
group, though evidence suggested that it had changed to a
form that may be less likely to clog arteries in both groups.
However, people who followed the Atkins diet had a 49 percent
decrease in triglycerides, an indicator for heart disease,
compared with a 22 percent decrease in those on the heart
association diet.
Though results
look promising, researchers mention that studies to date are
small and do not address long-term effects of the diet. More
research, in the form of larger, long-term studies, is necessary
before the diet will become widely recommended.
