Basal metabolic rate (BMR) is the number of calories your body needs to maintain basic functions while at rest. These functions include breathing, circulation, and cell production. BMR is usually measured in calories per day and varies from person to person based on factors such as age, sex, weight, and body composition.
Understanding BMR is important for health because it helps explain how many calories you burn in a day without any physical activity. Knowing your BMR can aid in weight management, as consuming more calories than your BMR can lead to weight gain, while consuming fewer can result in weight loss. BMR is a critical component in determining your overall energy needs.
BMR functions as the foundation of your body’s metabolism, which is the process of converting food into energy. Even when you are not active, your body requires energy for vital functions like maintaining body temperature, supporting brain function, and repairing cells. A higher BMR means that your body burns more calories at rest, which can be beneficial for maintaining a healthy weight.
In summary, BMR is a key factor in understanding how your body uses energy. By knowing your BMR, you can make more informed choices about your diet and activity levels. This knowledge can help you achieve your health goals effectively and sustainably.
