Yes.: Shivering most often is in reaction to exposure to cold external temperatures. The shivering is a reflection of twitching muscles, whose function is to generate heat via increasing their metabolism. Calories are a measurement of heat, though common usage of the term refers to the energy/potential heat content of food substances. Metabolism involves in effect a slow 'burning' of the food.
