Basal Metabolic Rate (BMR) is the minimum energy (calories) required by the body to perform vital functions such as breathing, blood circulation, and temperature regulation while at complete rest. It generally accounts for 60–70% of daily energy expenditure. BMR varies depending on age, gender, weight, height, and body composition. Several formulas are used for its calculation, such as the Harris-Benedict Equation (1919), Revised Harris-Benedict (1984), Mifflin-St Jeor (1990), and the WHO Formula. Knowing your BMR helps in planning proper nutrition, maintaining energy balance, and achieving weight management goals.
