The two most common ways to measure your resting metabolic rate (RMR) are by using a calorimeter or by using predictive equations. Your RMR is the number of calories you burn while at rest. It represents the minimum amount of energy your body needs to keep all of its vital functions working, such as your heart beating, your lungs breathing, and your brain functioning.
Your basal metabolic rate (BMR) is similar to your RMR, but it is a measure of the number of calories you burn while your body is at complete rest. This means that your BMR is the number of calories you would burn if you were to spend the entire day in bed. Your BMR is affected by a number of factors, including your age, gender, body size, and muscle mass.
The main difference between BMR and RMR is that BMR is a measure of the number of calories you burn while your body is at complete rest, while RMR is a measure of the number of calories you burn while at rest. RMR is a more accurate measure of the number of calories you burn in a day, as it takes into account the number of calories you burn while performing activities such as walking and talking.

How to Measure Your RMR and BMR?
There are several methods to measure your RMR and BMR. Both can be assessed in a clinical environment under specific conditions. BMR is typically measured after at least 8 hours of sleep and a 12-hour fast from food, caffeine, or other stimulants. The test is usually conducted in a dark room with the subject reclined, to achieve a natural state of rest. RMR can be measured with less sleep and fasting, which makes it less accurate than BMR. However, both methods provide personalized information about your body’s calorie needs.
Apart from clinical testing, you can use equations based on your personal measurements such as height and weight, to estimate your energy needs. There are also websites available that can calculate your numbers for you, but the results may vary and may not be as reliable as clinical or personal calculations.
The intermediate option is to use the Nutri Coach application to determine your daily caloric requirement. The result will be as accurate as possible.
