Fig. 2From: Cold exposure prevents fat accumulation in striped hamsters refed a high-fat diet following food restrictionBody mass (A), and food intake (B) of striped hamsters that were subjected to food restriction and were refed ad libitum. Food intake was restricted by 20% of ad libitum for two weeks (FR, day 8–21), the animals were then refed ad libitum for four weeks (Re, day 22–49). Control animals (CON) were kept constantly at 23 °C throughout the experiment. During the ad libitum refeeding period, animals were intermittently exposed to 5 °C for 2 h per day (ICE-2 h/d), 12 h per day (ICE-12 h/d), or persistently exposed to 5 °C (PCE). Data are means ± SEM. ** = significant difference across the four groups (P < 0.01)Back to article page
