Abstract：Body weight, food intake, basal metabolic rate (BMR), behavior, body fat, and gonad mass were measured in female KM mice that acclimated to a random food restriction (FR) and recovery. Food intake increased significantly, but body weight, gonad mass, BMR and activity decreased in FR mice and there was no group difference in fat mass. That all the parameters above recovered after re-feeding indicated a significant plasticity. The present data suggested that an energy trade-off was employed to meet unpredictable variation of food availability. The plasticity of energy metabolism and behavior played an important role in the trade-off strategy.
