The term for the minimum energy required to maintain basic physiological functions at rest is known as the basil metabolic rate (BMR). BMR represents the number of calories the body needs to perform essential functions, such as breathing, circulation, and cellular production, without any physical activity. Understanding one's BMR is important for creating effective dietary and exercise plans aimed at weight management. Factors influencing BMR include age, sex, weight, and body composition. Maintaining or adjusting caloric intake in accordance with BMR helps support overall metabolic health and weight goals.
