Definition: Basal metabolic rate (BMR) refers to the minimum amount of energy -- in the form of calories -- that your body requires to complete its normal functions, such as breathing, breaking down food, and keeping your heart and brain working. Age, gender, weight, and physical activity directly effect on basal metabolic rate.
BMR varies from person to person and increases with your amount of muscle tissue. Exercising increases your BMR, and it can stay raised after 30 minutes of moderate physical activity. Many people's BMR stays increased for approximately 48 hours following exercise.
Also Known As: BMR
