The term for the rate at which your body burns calories at rest is called the Basal Metabolic Rate (BMR). BMR represents the number of calories required to maintain basic physiological functions, such as breathing, circulation, and cell production, while at rest. Understanding BMR is crucial for individuals seeking to manage weight or improve fitness, as it helps determine daily caloric needs based on activity levels. Factors influencing BMR include age, gender, weight, and muscle mass. Measuring or estimating BMR can assist in creating effective dietary and exercise plans tailored to individual goals.
