Women with insulin resistance did better on a lower carbohydrate diet than on a low fat diet, according to findings in a study that came out of the University of Nevada School of Medicine, Reno. Insulin resistance is a very common precursor for type 2 diabetes.
"Forty-five obese women between the ages of 18 and 65 years participated in the study, and all had insulin resistance, as found by fasting blood levels of insulin. The researchers randomly assigned the women to either a low-fat or lower-carb diet. The groups did not differ significantly in average body weight, the authors reported. On average, women in the low-fat diet group weighed 213 pounds, while women in the other group weighed 223 pounds."
The lower carbohydrate diet had 20 percent of calories from protein, 45 percent from carbohydrates and 35 percent from mostly unsaturated fats. The low fat diet was 60 percent of calories from carbohydrates, 20 percent from fat and 20 percent from protein.
