Basal Metabolic Rate

Meaning

The Basal Metabolic Rate (BMR) represents the minimum amount of energy, measured in calories, required to maintain the fundamental physiological functions of the body at rest. This rate accounts for the energy expenditure necessary for vital activities such as breathing, circulation, cell production, and temperature regulation, excluding energy used for physical activity or digestion. Clinically, BMR is a crucial metric for understanding an individual’s energy needs and is significantly influenced by factors like lean body mass, age, and thyroid hormone status. A precise BMR assessment informs personalized nutritional and hormonal interventions aimed at optimizing body composition and overall health.
