  • Page 9: Chapter 1: Metabolic Measurements

    KORR™ Medical Technologies, Inc Chapter 1: Metabolic Measurements Metabolic Testing Metabolism is the process of converting food into heat or energy. The rate and efficiency with which the body converts food to energy is referred to as the metabolic rate.
  • Page 10 KORR™ Medical Technologies, Inc Calorie Calculation The number of calories expended for a given amount of oxygen consumed is 4.813 calories (0.0048 Kcal) for every milliliter of oxygen consumed. The exact relationship between calories consumed and oxygen consumption is also affected by the amount of carbon dioxide produced by the body as well as oxygen consumed.
