![]() The loss of lean muscle tissue also leads to a drop in BMR. If you consume fewer kilocalories, the body slows its metabolism (the rate at which it burns energy) to conserve energy. Body surface area Taller adults have more metabolising tissue than shorter-statured ones, which means they burn more calories-leading to a higher BMR.Many factors contribute to your BMR, such as: This calculation is not always accurate because it does not consider other activities or exercises and variables such as muscle mass, diet, weather, genetics, pregnancy, and supplements. To calculate your BMR, you need to know your weight, height, age, and gender and add those details to the basal metabolic rate formula (like the one below) to determine how many calories you need to burn daily to maintain normal healthy physiology. BMR Calculation Formula- The Harris-Benedict equation revised by Roza and Shixgal ![]() This is how you can utilise the BMR calculator to lose weight or track how well your diet and exercise routine are working for you.

Why is BMR Calculator important?īecause it gives you an idea of how many calories you burn every day at rest-understanding your BMR allows you to set realistic fitness goals, including losing weight or gaining muscle mass. The Basal Metabolic Rate calculator is a simple tool used to estimate the basal metabolic rate of your body and measure the kilocalories required to sustain life processes at rest-essentially, what your body needs to keep you healthy.īecause BMR measures the rate at which one’s body burns calories when a person is resting, it can only be accurately calculated after fasting for 12 hours and getting a whole night’s sleep-with no physical activity or emotional excitement.
