Study compares low-carb and low-fat diets
by Mike Adams, the Health Ranger, NaturalNews Editor
Americans continue to engage in low-carb diets, with many thinking that it is the best way to lose body fat. A researcher at the Albert Einstein College of Medicine is studying the question, and she believes that low-carb diets seem to outperform low-fat diets in controlling triglycerides, one of the factors in heart disease. She believes that current low-carb diets are healthy for the heart.
It may not be a question for the ages, but Americans continue to wonder whether low-carbohydrate diets are a safe and effective way to lose body fat.
Dr. Carol-Jean Segal-Isaacson is working to answer that question.
Though scientists need to conduct more research into the long-term effects of low-carb diets, Segal-Isaacson said low-carb diets appear to do a better job of controlling triglycerides, one factor in heart disease, than low-fat diets.
"The modern version of the Atkins Diet focuses on lower-fat protein sources, such as chicken and fish, with more moderate amounts of red meats," Segal-Isaacson said.
Meat consumption is not the only threat to heart health, Segal-Isaacson said.
"Sugars, simple carbohydrates, can also be a risk factor.
An important question to be answered is whether a drop in triglycerides counters the increase in low-density lipoprotein (LDL) cholesterol that some people experience on low-carb diets.
High levels of LDL cholesterol and triglycerides, and low levels of HDL cholesterol, increase the risk of heart disease.
Segal-Isaacson points out that the American Heart Association and the American Diabetes Association are moving away from the stance that the low-fat diet is always the best diet for everyone.
"I think there's a growing consensus that the Mediterranean diet may be a better health recommendation.
Segal-Isaacson is participating in CCARBS (The Controlled Carbohydrate Assessment Registry Bank Study), an Internet-based study, started in 2003, that is tracking 2,499 subjects' ability to adhere to low-carb diets and their ability to lose weight.
The first year's data suggests only 30.3 percent of the 277 respondents lost more than 5 pounds, 34.7 percent basically maintained their weight and 35 percent gained weight.
That weight gain resulted from increased intake of carbohydrates and a decrease in physical activity, Segal-Isaacson said.
