Body weight gain was not significantly modified either by glucose feeding or by corn oil or argan oil despite a trend to a diminution of body weight gain, which was observed with argan and corn oil treatments (206.4 24.5 g in control; 215.3 18.9 g in glucose treated; 186.3 12.8 g in glucose þ corn oil; 188.4 13.0 g in glucose þ argan oil). As shown in Figure 2, the 5-wk glucose feeding, with or without corn oil, significantly increased (P < 0.01) blood glucose levels in overnight-fasted rats. The chronic treatment with argan oil reduced the increase in glucose levels in glucose fed rats so that the blood glucose in argan oil glucose-treated rats was
