*Basal Metabolic Rate is calculated by the Harris-Benedict equation (created in 1919, but still applicable today).
Basal metabolic rate (BMR) is defined as the total number of calories required by your body to carry out some of the basic life-supporting functions. Specifically, BMR meaning states the total energy exhausted while you are at a resting mode. While you are doing nothing, your body is still working and performing certain functions which are known as basal functions. These include breathing, circulation of blood, protein synthesis, cell construction, processing and absorption of nutrients, and ion transport.
So you can calculate BMR online, find your calorie requirement to lose or gain weight using a BMR calculator or by manually using a mathematical formula.
Full Form of BMR – Basal Metabolic Rate
Every living being needs a certain amount of calories to live and perform body functions. This minimum number of calorie requirement is known as the basal metabolic rate (BMR). The organs present in the body needs this minimum number of calories to function properly even if you are performing no activity. This means the total amount of energy consumed while you are at rest.
As your basal metabolic rate is dependent on the natural functions such as circulating blood and breathing, any alterations in your daily activities will not increase or decrease your BMR. But on the other hand, your muscle mass does affects your BMR. The reason behind is your muscles require more energy to retain and sustain more muscles. This implies that you will burn more calories during resting phase when you have more muscle mass.
You can calculate BMR manually by using any of the formulas devised. There are different formulas for calculating the Basal metabolic rate for men and women. Men usually have greater percentage of lean body weight than women so we need to calculate BMR with different formulas.
For carrying out BMR calculations, we have given the Mifflin – St Jeor bmr formula (created in the year 1990, superseding the 1919 Harris-Benedict formula). So you can calculate BMR by using any of the BMR formula underneath:
BMR (metric) = (10 × weight in kg) + (6.25 × height in cm) – (5 × age in years) + 5
BMR (imperial) = (4.536 × weight in pounds) + (15.88 × height in inches) – (5 × age) + 5
BMR (metric) = (10 × weight in kg) + (6.25 × height in cm) – (5 × age in years) – 161
BMR (imperial) = (4.536 × weight in pounds) + (15.88 × height in inches) – (5 × age) – 161
RMR stands for “resting metabolic rate.” The only difference between BMR and RMR is that BMR only calculates basic functions of breathing, circulation, and temperature regulation while you are completely on a resting mode. On the other hand, RMR measures the amount of energy exhausted by digestion and non-exercise daily activities, such as changing your dress or lifting your toothbrush in your hand and brushing your teeth.
Once you’ve calculated your BMR, you will be able to calculate your daily requirement of calories.
Getting to know about your basal metabolic rate and the number of calories you require each day is an added advantage to reach your fitness goals. Using calculate my BMR, you can easily track the amount of calories you need for your weight loss or weight gain journey. BMR and weight loss/weight gain are connected to each other as once you know your BMR, this number will help you lose weight/gain weight by keeping track of your calories.
