(A) Relative interscapular brown adipose tissue (BAT) mass in rats fed either a standard diet (Std), coconut diet (Coco) or butter diet (Butter). Data are means ± SEM; n = 10 for standard group, coco group, and n = 4 for butter group. P < 0.05. (B) Western blot analysis of UCP1 content in brown adipose tissue from rat fed standard diet, coconut diet or butter diet. Detections were performed with 40 μg of BAT mitochondrial proteins. Negative control was liver from standard rats. (C) 3-hydroxyacyl-CoA dehydrogenase (HAD) activity is measured spectrophotometrically and expressed in micromoles per minute per gram protein. Data are means ± SEM; n = 8 for standard group, coco group, and n = 4 for butter group. P < 0.05.
