Conjugated linoleic acid, or CLA, has been touted for its antioxidant and even its anti-cancer properties. Naturally found in meat, eggs and dairy, especially grass-fed, it is also widely available in supplements. Now, research has found that it may also fight belly fat.

A small study in the American Journal of Clinical Nutrition adds to the growing body of research showing CLA may be effective at reducing fat around the middle. In the current study fifty-five obese postmenopausal women with type 2 diabetes received either safflower oil or CLA during two 16-week diet periods separated by a 4-week "washout" period.

Women who received CLA had reduced body mass index and total fat tissue without altering lean mass. The effect of the CLA in lowering BMI was detected during the last 8 weeks of each 16-week diet period. The women taking CLA lost an average of 4 pounds of fat from around their waist area.
