Arms Assigned Interventions
Placebo Comparator: Safflower Oil
8.0 g/day safflower oil
Dietary Supplement: Safflower OIl
8.0g/day safflower oil
Experimental: CLA 6.4g/day
Conjugated linoleic acid at a dose of 6.4g/day in a supplement with a total of 8.0g oil
Dietary Supplement: Conjugated Linoleic Acid (CLA)
6.4 g CLA/day, capsule form, for 16 week arms

Detailed Description:

The design is a double-blind, placebo-controlled, crossover study conducted at a single site. The primary variable is a change from baseline to Week 16 in plasma glucose area under the curve during a three-hour oral glucose tolerance test. Secondary variables include changes in fasting levels of glucose and insulin, glucose tolerance, hemoglobinA1c, hepatic enzymes, adipocytokines, blood lipid profile, and body composition. Supporting endpoints include dietary intake, physical activity, fatty acids, and vital signs.
