Your basal metabolic rate (BMR) is the number of calories your body needs to realize its most basic (basal) life-sustaining functions, such as breathing, blood circulation, nutrient processing, and cell production. If you are looking to reach or maintain a healthy weight, you may find it helpful to calculate your BMR. Once you know your BMR, it can then be used to calculate your Total Daily Energy Expenditure (TDEE) i.e., the number of calories you are spending in your daily life. TDEE calculations consider your daily physical activity levels on top of your BMR. TDEE becomes the basis for you to arrive at the number of calories you need to consume in order to maintain, gain, or lose weight. Knowing your BMR & TDEE is a progressive step in the process of reaching or maintaining a healthy body weight. When you have empowered yourself with this all-important information, you can make informed lifestyle changes to bring the much sought after results in your physical transformation.
