What is BMR?
You use energy no matter what you're doing, even when sleeping. Your BMR (Basal Metabolic Rate) is an estimate of how many calories you'd burn if you were to do nothing but rest for 24 hours. It represents the minimum amount of energy needed to keep your body functioning, including breathing and keeping your heart beating.
Your BMR decreases as you age. Likewise, depriving yourself of food in hopes of losing weight also decreases your BMR, a foil to your intentions. However, a regular routine of cardiovascular exercise can increase your BMR, improving your health and fitness when your body's ability to burn energy gradually slows down.
How to calculate BMR?
Calculating your BMR may be quite a difficult process. The formula used for BMR is different for both the genders. One of the easiest and simplest ways in which you could calculate your BMR is by using the calculator available here. The result you get will indicate how many calories your body actually requires to perform some of the most basic functions such as breathing, digesting food and carrying out daily activities. BMR also depends on the physical activity that you do throughout the day.
