Many animal species living in temperate zones show annual body fat cycles. In an apparent regulation of total body fat, species showing naturally occurring decreases in adiposity in the fall (e.g., meadow voles and Siberian hamsters) are resistant to high-fat diet (HFD)-induced obesity in short, "winter-like" days (SDs), and in long, "summer-like" days (LDs) at their peak adiposity. SD-exposed Shaw's jirds (Meriones shawi) show SD-induced decreases in body fat; therefore, we predicted they also… CONTINUE READING
