Resveratrol effects on parameters of energy balance. Six male mouse lemurs were observed during one week of ad libitum feeding (Control), followed by four weeks of RSV supplementation to the ad libitum feeding (RSV1, 2, 3 and 4). The curves represent the evolution with time of food intake (A), body-mass gain (B), resting metabolic rate (RMR) (C) and daily amount of locomotor activity (LA) (D). Values are given as mean ± SEM. Resveratrol supplementation induced a significant decrease in food intake and body-mass gain associated with an increase in RMR. The amount of LA was not modified by the treatment.
