What is the meaning of basal metabolic rate?
Flexi Says:
Besides shivering, another way to increase body heat is to raise the basal metabolic rate. The basal metabolic rate (BMR) is the amount of energy that a person needs to keep the body functioning at rest. The higher the BMR, the more heat the body generates, even without exercise or physical labor. The BMR can be increased by consuming large quantities of high-calorie fatty foods. People living in very cold subarctic regions, including the Inuit, traditionally ate whale and seal blubber and other high-fat foods, which helped them maintain a high BMR and stay warm.
