There are two types of fats, the brown ones and the white ones. White fats can be visible on your belly, thighs and on the back of the arms. It has been proven scientifically that cold temperatures eliminate white fats.If you stay in cold temperatures for a prolonged period of time, your white fats will start transforming into brown fatty tissues. White fats have a brown color during cold seasons. It is recommended by the experts from the “Maastricht University Medical Centre” to maintain the temperature of the room at 15-17 °C during the cold season, because a warm room can stop your body from burning fats.
