In order to compute how many calories your body requires for it to function properly you will need to enter your age, gender, weight and height so that your data can be then put in some formulas that determine this personalized value. When using the Metric units: Female - RMR = 655 + (9.6 x weight in kg) + (1.8 x height in cm) - (4.7 x age in years). PNAS 4 (12): 370–3. If you wish to lose weight in a healthy way, you may want to consider a daily caloric intake that is between the RMR and RMR x 1.5 and to accompany your diet with suitable exercise and lifestyle changes. It is measured in kilo joules per hour per kilogram of body mass. Resting Metabolic Rate helps in estimating the calories required for various functioning of the vital organs and processes during rest(7) BMR or Basal Metabolic Rate represents the total number of calories the body burns when it is in total rest devoid of any external influences.It is the largest component of total caloric value((8) Age – The more elderly and limber an individual, the lower their BMR, or the lower the minimum caloric intake required to sustain the functioning of their organs at a certain level. StyleCraze provides content of general nature that is designed for informational purposes only. Genetics: The genes play an important role in deciding RMR.Some people are born with faster metabolism and some have lower metabolism . Resting metabolic rate is the energy required by an animal to stay alive with no activity. An accurate BMR measurement requires that a person's sympathetic nervous system is inactive, which means the person must be completely rested. Practically this is the amount of energy expended for keeping our body alive with all the vital functions (for instance, but not limited to: heart beating, nervous system, skin, muscles). … While the two are used interchangeably, there is a key difference in their definitions. Resting metabolic rate slows down as the age increases and weight decreases. (16), To embed this on to your site just copy and paste the below code. This resting metabolic rate calculator will provide you with an estimate of how many calories a day you burn at rest. BMR increases approximately 7% for every increase of 1.36 degrees Fahrenheit in the body's internal temperature. Here are some examples of cases and their respective results. The formulas employed are described below. The Basal Metabolic Rate (BMR) Calculator estimates your basal metabolic rate—the amount of energy expended while at rest in a neutrally temperate environment, and in a post-absorptive state (meaning that the digestive system is inactive, which requires about 12 hours of fasting). Muscle Mass:The higher the muscle mass the more the RMR and vice versa. It was revised in 1984 to be more accurate and was used up until 1990, when the Mifflin-St Jeor Equation was introduced. The resting metabolic rate calculator estimates the amount of calories used by your organism to keep it alive (in rest time). The RMR calculator has two tabs which would be helpful for easier measurements.YOu can enter weight in either lbs or kgs and height in feet or in cms(5). The resting metabolic rate (RMR), also known as basal metabolic rate (BMR) represents the amount of energy expended daily by the body when resting (or when sleeping), so to keep vital functions such as respiration or heart beating but with no additional activity. The more muscle mass in the physical composition of an individual, the higher the BMR required to sustain their body at a certain level. Pregnancy – Ensuring the livelihood of a separate fetus internally increases BMR. The daily caloric need is the BMR value multiplied by a factor with a value between 1.2 and 1.9, depending on activity level. So it means that even when sleeping our body burns calories. 1) Harris J, Benedict F. (1918) A Biometric Study of Human Basal Metabolism. Mifflin St. Jeor derived a formula to find the resting metabolic rate. The Harris-Benedict Equation was one of the earliest equations introduced. Harris J, Benedict F. A Biometric Study of Human Basal Metabolism. Also, menopause can increase or decrease BMR depending on hormonal changes. On the other hand, starvation can reduce BMR by as much as 30%. Please note that once you have closed the PDF you need to click on the Calculate button before you try opening it again, otherwise the input and/or results may not appear in the pdf. The three equations used by the calculator are listed below: Muscle Mass – Aerobic exercise such as running or cycling has no effect on BMR. Genes and environmental temperature have a significant role in metabolic rate changes. If you've noticed that every year, it becomes harder to eat whatever you want and stay slim, you've also learnt that your BMR decreases as you age. It is measured in kilo joules per hour per kilogram of body mass. Your metabolic rate = your resting metabolic rate (easy to calculate reasonably accurately) + energy consumed by your daily activities (must guestimate). Your BMR slows down at roughly 2% every 10 years after the age of 20. :BMR*1.2, Mild activity such as intensive exercise for at least 20 minutes 1-3 times per week: BMR*1.3, Moderate Activity Level: This includes intensive exercise for for 30-60 minutes , 3 to 4times per week: BMR*1.55, High Activity Level includes intensive exercise of 60 minutes or greater for 5-7 days per week such as farming, construction work, rickshaw puller etc: BMR *1.7, Extreme Activity Level:This includes extreme activities such as athletes with strenuous training schedule, shovelling coal or working long hours in an assembly line: BMR* 1.9 (10). When working towards any sort of health or fitness goals, BMR can aid in laying down the foundations, but from there on it has little else to offer. You can perform this test in either metric or imperial measurements. You can use either the metric or US measurements for this online tool. This calculator is based on the widely used and accepted Harris-Benedict equations for determining basal metabolic rate BMR, with a modification incorporated to account for calories burned to support digestion of food.The basal metabolic rate estimates are simply increased by 10% (representing additional calorie burn required to digest food) to arrive at a resting metabolic rate estimate. The RMR formula (practically the BMR formula because most people refer to Basal Metabolic Rate): Female - RMR = 655 + (4.35 x weight in pounds) + (4.7 x height in inches) - (4.7 x age in years). This calculator uses Mifflin St. Jeor equation to find the resting metabolic rate. RMR is also known as BMR (basal metabolic rate). RMR is the amount of calories that is burned while in complete rest. All Rights Reserved. It is better to consult a certified specialist or measure BMR through a calorimetry device. Essentially, an average person eating an average diet will likely have expected BMR values, but there are factors that are still not understood that determines BMR precisely. This is why pregnant women tend to eat more than usual. When you are ill or sick, your RMR (resting metabolic rate) increases in order to be able to fight the infection. By now you are probably wondering how you can put this index to use and how knowing the basic calorie requirement of your body will help you establish your usual daily calorie intake.
