Adult rats were treated subcutaneously for 10 days with capsaicin, and their food intake and body weight were recorded for almost 6 weeks after stopping the treatment. The animals were exposed to different ambient temperatures: Ta (22, 32, 35, 10 and 22°C). In the capsaicin-treated group a persistent increase in food intake and a reduction of body weight were observed when the animals were exposed to the lowest T a of 10°C. Starting from this temperature, food intake remained significantly higher than in controls until the end of the experiment at a Ta of 22°C. The discrepancy between body weight increase and food intake especially at low temperature (10°C) suggests that capsaicin could prevent suppression of food intake through the mediation of capsaicin-sensitive vagal afferent fibers by activation of cold-temperature-sensitive receptors.
