Your basal metabolic rate (BMR) is the energy used (measured in calories) by your body to perform basic functions, including internal energy expenditure, breathing, and body temperature. It is the number of calories your body would expend if you performed no physical activity throughout the day. The calculator determines your BMR using multiple factors, including height, weight, age, and gender.
BMR is influenced by age, gender, weight, muscle mass and body size, and environmental temperatures.
