THURSDAY, July 9 (HealthDay News) -- The dietary oils, conjugated linoleic acid and safflower oil, may help postmenopausal women with diabetes mellitus to lose weight, according to a study published online June 17 in the American Journal of Clinical Nutrition.

Leigh E. Norris, of Ohio State University in Columbus, and colleagues conducted a study of 35 women who completed a 36-week intervention whereby they added either 8 grams of safflower oil or conjugated linoleic acid a day to their diets for 16 weeks, separated by a four-week washout period, without making any other changes to their diet.

After the women had been on the conjugated linoleic acid diet for eight weeks, the researchers found evidence of reduced body mass index and total adipose mass, while the safflower diet did not have any effect on either measure but did reduce trunk adipose mass and increase lean mass, as well as significantly lower fasting glucose. Dietary fat intake, energy intake and fat quality were found to be similar for both interventions.

"Making this subtle change in the intake of high-quality dietary fats in an effort to alter body composition is both achievable and affordable to postmenopausal women in the United States who are managing the difficult combination of obesity and diabetes," a co-author of the study said in a statement.
