The less you wear in winter, the more fat you accumulate. The human body will have a self-protection mechanism. Since I feel cold, I may add fat to keep warm. Whether to wear less in cold weather, burn fat or store fat. Burning and storing fat has little to do with cold weather or how much you wear. There is a certain limit to the body's automatic temperature regulation. Wear less clothes and have a low body temperature when it is cold. Through the secretion of adrenaline, the human body accelerates energy consumption and temporarily raises body temperature. But this process is only short-term, and it mainly consumes sugar, not fat. Only by increasing the amount of exercise during freezing will you consume fat. If the body temperature is kept low for a long time, the body will gradually convert some sugar into fat, which is a physiological behavior of self-protection evolved by warm-blooded animals and cannot be controlled by itself. Moreover, people with long-term low temperature will subconsciously consume a lot of high-calorie food when eating, which will also promote fat accumulation.
