Basal metabolic rate (BMR) refers to the amount of calories your body requires to maintain its most basic functions such as breathing, cell reproduction, etc.
Your BMR could be used as a baseline to maintain, lose or gain weight, depending on your goal. If a person's BMR and activity level are known, then it is possible to calculate the amount of daily calories needed to achieve a certain goal.
As a rule of thumb, it is always reccommended to seek a qualified professional before you decide to cut back or increase the amount of daily calories consumed. If not done properly, it could have serious consequences to your physical and/or mental health.
The most famous way to calculate BMR is by utilizing the Harris-Benedict equation.
For men, BMR = 88.362 + (13.397 x weight(kg)) + (4.799 x height(cm)) - (5.677 x age)
For women, BMR = 447.593 + (9.247 x weight(kg)) + (3.098 x height(cm)) - (4.330 x age)
A multiplier can also be utilized based on activity level. With our calculator you can choose to utilize it or not.
