![]() ![]() The body uses this energy to maintain basic functions such as breathing, cell production and temperature control. This figure represents the minimum number of calories your body requires to continue functioning. This calculation uses the Mifflin - St Jeor (1990) formula 1Īnd returns a figure known as your Basal Metabolic Rate (BMR). Your BMR is calculated by entering your height, weight and age figures into the BMR formula. What is the difference between BMR and RMR?.We hope our BMR calorie calculator has been of help to you and you have found the proper amount of kcals to maintain this BMR. Women: (10 × weight in kg) + (6.25 × height in cm) – (5 × age in years) – 161.Īnd then the last formula of the most popular options that are out there is:.Men: (10 × weight in kg) + (6.25 × height in cm) – (5 × age in years) + 5.For women: BMR = 655.1 + (9.563 x weight in kg) + (1.850 x height in cm) – (4.676 x age in years)īut there are a few options out there to explore.We find that the most accurate, on average, is the Harris-benedict formula. Are There Any Other Ways to Calculate BMR? In healthcare, the RMR formula is used and looked at when needed, but total daily expenditure is the general formula used when looking at health and dieting. It is still always a great number for you to know and at least aim to take in to maintain your current weight. If you were to use this number as a way to diet and eat under this basal metabolic weight, you are guaranteed to go through weight loss, but it is not the healthiest of ways to go about this goal. If you want to maintain your body weight, it may be better to use RMR since it is unlikely you will be without any form of activity and in a state of pure rest. So, we can use our BMR in the sense that it is used for a greater calculation of the total daily expenditure. Ideally, you will use your BMR to find the overall amount of energy you need in a day by calculating your total daily expenditure.Īs we have stated, a change in your lean body mass, like if you were to build muscle, will cause greater differences in calorie intake to reach whatever your BMR may be. Can I Use My BMR to Gain Muscle, Lose Fat, or Change my Body Fat Percentage? The two numbers will come out very close to one another but not always the same, so make sure that you clarify which one is asked for in certain equations. So, they are both very similar since the BMR is included inside of the RMR. This is one example where they could differ more greatly. If someone works a more physical job, their non-exercise movements will be greater and their resting metabolic rate will be much higher than the BMR. Still, it also includes the energy expended through the digestion of food and daily non-exercise movements. RMR, which is short for Resting Metabolic Rate, is everything included within the basal metabolic rate. In reality, the two words are different and not interchangeable.īMR, as we have discussed, is the Basal metabolic rate and is the bare minimum to keep the body alive with involuntary functions and being in a resting state. Many people use the terms RMR and BMR as interchangeable words with no real difference. ![]() It might be better to use our TDEE calculator and find a healthy total daily expenditure first to find what a healthy amount of calories would be for your own health and fitness goals. If you are taking in less than your basal metabolic rate, then you would definitely be in a calorie deficit, not including your other factors for TDEE. Again, it is highly related to the makeup of your body and the bare minimum daily calories needed to sustain it. How to become a strength and conditioning coachĪ healthy BMR depends mostly on the makeup of your body and your BMI. ![]()
