Final body weight, body composition, food intake, tissue weight, and total white blood cell counts (WBC) and adipokines after 24 wk on a control (Con = AIN-93M) or a high fat diet (HF = 45% kcal from fat) in C57BL/6J, C57BL/6N, and C3H/HeJ mice. Values are means ± SE, mice in each group. values show the differences between dietary treatments within a given strain.
