RMR Calculator: Learn Your Resting Metabolic Rate for Weight Loss	Because so many factors can affect your BMR—age, height, weight, body composition, hormones, stress levels, nutrition, caffeine intake, and more—it is difficult to set acceptable guidelines or standards for BMR measurements. On average, BMR decreases almost linearly with age due to changes in hormones and loss of lean muscle mass as strenuous physical activity tends to decline with age. In order to offset or "fight back" against this decline in BMR, you must maintain healthy lean muscle mass. In other words, muscle is the key. While cardio exercise is good for your heart, it will not raise your BMR. Online BMR calculators provide a fairly accurate measure of BMR. While these BMR calculators do not include factors such as stress level, caffeine intake, nutrition, or hormone levels, they utilize measurable factors and basic BMR calculations to properly measure actual BMR. If you require an exact measurement, many doctor's offices, nutrition professionals, and even gyms can run tests using a special calorimetry device. While it is not necessary to know your Basal Metabolic Rate to lose weight, it may be helpful. And knowing your TMR total metabolic rate is an even more helpful tool, as TMR measures the total kilocalories that your body burns on a daily basis. Remember that weight loss is not as simple as creating a calorie deficit, as many believe. Other factors, like hormones, can significantly affect your weight loss or weight gain goals.

Understanding your BMR may help you determine how best to eat for your body type, and using a BMR calculator is an easy way to find this number. Calculate: Caloric Needs Basal Metabolic Rate BMR. Gender Male Female. Weight Pounds. Age Years. Calculate Reset. Your Basal Metabolic Rate BMR is:. What is BMR? BMR or RMR can be used to estimate total daily caloric expenditure. According to the American Council on Exercise , after you determine your RMR, based on one of the above equations or an online calculator, you can multiply it by one of the numbers below, called activity factors:. If the man in the above example exercises two days per week, his daily caloric expenditure is roughly 2, to 2, calories. If the woman in the above example exercises six days per week, her daily caloric energy expenditure is roughly 2, to 2, calories. This calculation gives you the estimated number of calories you burn in one day at your current level of activity; this is how many calories you need to consume per day to stay at your current weight. To lose weight, you need a caloric deficit, meaning that you either must reduce your caloric intake below your total daily energy expenditure or increase your total daily energy expenditure, says Greaves. For example, you can try multiplying your RMR by various activity factors to see how your daily caloric burn would fluctuate with increased exercise. Another benefit of increased exercise is that it can have a small effect on both RMR and BMR. Research shows that intense exercise provides a temporary boost to your RMR, an effect sometimes referred to as afterburn, or excess post-exercise oxygen consumption EPOC. This represents the calories that the body expends to return the body to homeostasis following exercise. As previously stated, a pound of fat burns roughly two calories per day while a pound of muscle burns six at rest, Church says. To put that into perspective, gaining two pounds of muscle will increase RMR by about 12 calories.

What Is Basal Metabolic Rate? Medically reviewed by Imashi Fernando, MS, RDN, CDCES — By Scott Frothingham — Updated on May 5, BMR vs RMR Estimating BMR Purpose How many calories do you need every day? Resting metabolic rate is modulated by the amount of calories consumed in the diet relative to energy expenditure. Excessive consumption of energy appears to increase resting metabolic rate while fasting and very low calorie dieting causes resting metabolic rate to decrease. Since the metabolic rate at rest is the primary component of daily energy expenditure, its reduction with caloric restriction makes it difficult for obese individuals to lose weight and to maintain weight that is lost. Whether exercise has a carry-over effect on resting metabolic rate remains controversial, even though this question has been studied extensively during the last 90 years. For example, if a man is pounds, 5'11", 43, and his body-fat percentage is 20 percent, his RMR is 1, calories. For example, if a female pounds, 5'3", 36, and her body-fat percentage is 25 percent, her RMR is 1, calories. BMR or RMR can be used to estimate total daily caloric expenditure. According to the American Council on Exercise , after you determine your RMR, based on one of the above equations or an online calculator, you can multiply it by one of the numbers below, called activity factors:. If the man in the above example exercises two days per week, his daily caloric expenditure is roughly 2, to 2, calories.

The Katch-McArdle Formula is slightly different in that it calculates resting daily energy expenditure RDEE , which takes lean body mass into account, something that neither the Mifflin-St Jeor nor the Harris-Benedict Equation does.

Of these equations, the Mifflin-St Jeor Equation is considered the most accurate equation for calculating BMR with the exception that the Katch-McArdle Formula can be more accurate for people who are leaner and know their body fat percentage.

You can pick the equation to be used in the calculation by expanding the settings. where: W is body weight in kg H is body height in cm A is age F is body fat in percentage. Muscle Mass — Aerobic exercises, such as running or cycling, have no effect on BMR. However, anaerobic exercises, such as weight-lifting, indirectly lead to a higher BMR because they build muscle mass, increasing resting energy consumption.

The more muscle mass in the physical composition of an individual, the higher the BMR required to sustain their body at a certain level. 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.

Weather — Cold environments raise BMR because of the energy required to create a homeostatic body temperature. Likewise, too much external heat can raise BMR as the body expends energy to cool off internal organs.

Diet — Small, routinely dispersed meals increase BMR. Pregnancy — Ensuring the livelihood of a separate fetus internally increases BMR. This is why pregnant women tend to eat more than usual. Also, menopause can increase or decrease BMR depending on hormonal changes. Supplements — Certain supplements or drugs raise BMR, mostly to fuel weight loss.

Caffeine is a common one. Online BMR tests with rigid formulas are not the most accurate method of determining an individual's BMR. It is better to consult a certified specialist or measure BMR through a calorimetry device. A comprehensive treatment of confounding factors on BMR measurements is demonstrated as early as in Massachusetts by Engineering Professor Frank B Sanborn, wherein descriptions of the effects of food, posture, sleep, muscular activity, and emotion provide criteria for separating BMR from RMR.

In the s for the French Academy of Sciences, Lavoisier , Laplace , and Seguin investigated and published relationships between direct calorimetry and respiratory gas exchanges from mammalian subjects.

In the early 20th century at Oxford University, physiology researcher Claude Gordon Douglas developed an inexpensive and mobile method of collecting exhaled breath partly in preparation for experiments to be conducted on Pike's Peak, Colorado.

In this method, the subject exhales into a nearly impermeable and large volume collection bag over a recorded period of time. The entire volume is measured, the oxygen and carbon dioxide content are analyzed, and the differences from inspired "ambient" air are calculated to determine the rates of oxygen uptake and carbon dioxide output.

To estimate energy expenditure from the exhaled gases, several algorithms were developed. One of the most widely used was developed in at University of Glasgow by research physiologist J.

In the early s, computer technology enabled on-site data processing, some real-time analysis, and even graphical displays of metabolic variables, such as O 2 , CO 2 , and air-flow, thereby encouraging academic institutions to test accuracy and precision in new ways. For example, a demonstration of the mobile system with digital display of both cumulative and past-minute oxygen consumption was presented in at the Proceedings of the Physiological Society.

In the new millennium, smaller "desktop-sized" indirect calorimeters were being distributed with dedicated personal computers and printers, and running modern windows-based software. RMR measurements are recommended when estimating total daily energy expenditure TEE.

Since BMR measures are restricted to the narrow time frame and strict conditions upon waking, the looser-conditions RMR measure is more typically conducted. Thermochemistry aside, the rate of metabolism and an amount of energy expenditures can be mistakenly interchanged, for example, when describing RMR and REE.

The Academy of Nutrition and Dietetics AND provides clinical guidance for preparing a subject for RMR measures, [16] in order to mitigate possible confounding factors from feeding, stressful physical activities, or exposure to stimulants such as caffeine or nicotine:.

In preparation, a subject should be fasting for 7 hrs or greater, and mindful to avoid stimulants and stressors, such as caffeine, nicotine, and hard physical activities such as purposeful exercises.

For 30 minutes before conducting the measurement, a subject should be laying supine without physical movements, no reading nor listening to music. The ambiance should reduce stimulation by maintaining constant quiet, low lighting, and steady temperature.

These conditions continue during the measurement stage. Further, the correct use of a well-maintained indirect calorimeter includes achieving a natural and steady breathing pattern in order to reveal oxygen consumption and carbon dioxide production rates under a reproducible resting condition.

Indirect calorimetry is considered the gold-standard method to measure RMR. Long-term weight management is directly proportional to calories absorbed from feeding; nevertheless, myriad non-caloric factors also play biologically significant roles not covered here in estimating energy intake.

Thus, estimation of REE by indirect calorimetry is strongly recommended for accomplishing long-term weight management, a conclusion reached and maintained due to ongoing observational research by well-respected institutions such as the USDA , AND previously ADA , ACSM , and internationally by the WHO.

RMR is regularly used in ecology to study the response of individuals to changes in environmental conditions. Parasites by definition have a negative impact on their hosts and it is thus expected that there might be effects on host RMR. Varying effects of parasite infection on host RMR have been found.

Most studies indicate an increase in RMR with parasite infection, but others show no effect, or even a decrease in RMR.

Resting metabolic rate -

This includes basic functions such as:. Keep in mind that your BMR includes only the energy calories necessary for basic, life-sustaining functions. It does not include additional calories needed for daily activities, such as walking, moving, and exercising. This calculator uses your age, size, sex, and activity level to estimate the number of calories you should eat per day to maintain your weight.

Keep in mind that this tool provides only general guidance. Your activity level and many other factors influence your daily calorie needs. A doctor or dietitian can offer more individualized advice on your ideal calorie intake, depending on your health status and goals. Note: This calculator calculates your total daily energy expenditure TDEE , which is the total number of calories your body burns in a day, including movement and physical activity.

Your BMR can be calculated using direct calorimetry , indirect calorimetry, or a quick math equation. However, since most people do not have access to these devices, researchers have developed more convenient methods of calculating BMR.

In particular, the Mifflin-St. Jeor equation is a popular way to calculate it quickly. Technically, this equation calculates your resting metabolic rate RMR , which is slightly different from BMR. RMR determines the calories you burn at rest with minimal movement.

BMR is more restrictive and measures calories with zero movement in the day. However, BMR and RMR are often used interchangeably, and calculating your RMR should get you a pretty close estimate of your BMR. For example, a year-old, pound A year-old female who weighs pounds 68 kg and is 5 feet 7 inches cm tall will burn around 1, calories per day at rest.

To calculate your TDEE the total calories you need each day , you need to multiply your BMR by an activity factor. However, specificity is key when reporting on research participants and clinical findings, so we use the same language that the studies we cite use. We encourage you to talk with a qualified healthcare professional if you need support navigating how the information in this article may apply to you.

Although the Mifflin-St. Eating only enough calories to match your BMR is not safe or healthy. Finally, while knowing your BMR can provide some insight, it does not paint a full picture of your health.

For instance, your muscle-to-fat mass, underlying health conditions, hormone levels, and other metrics are also important aspects of health. Counting calories and tracking exercise have both been associated with greater eating disorder symptoms. If you are preoccupied with food or your weight, feel guilt surrounding your food choices, or routinely engage in restrictive diets, consider reaching out for support.

These behaviors may indicate a disordered relationship with food or an eating disorder. Disordered eating and eating disorders can affect anyone, regardless of gender identity, race, age, body size, socioeconomic status, or other identities. They can be caused by any combination of biological, social, cultural, and environmental factors — not just by exposure to diet culture.

Your BMR tells you how many calories you burn at rest. This number will give you a general idea of how many calories your body needs per day to maintain your current weight.

BMR — which is often used interchangeably with resting metabolic rate, or RMR more on that later — is one of many factors in the total number of calories you burn in a given day, also called your total daily energy expenditure TDEE.

It accounts for roughly 60 to 75 percent of your TDEE, according to the National Academy of Sports Medicine NASM. TDEE is determined by genetics, biological sex, age, body size, and lean body mass. Hormonal health can also affect metabolism.

Age is also a factor, he says. At rest, a pound of fat burns roughly two calories per day and a pound of muscle burns roughly six calories, Dr. Church says. RELATED: A Scientifically Proven Way to Lose 1 Pound of Weight. It is typically determined only in laboratory settings, with people undergoing measurements in a darkened, temperature-controlled room immediately after 8 hours of sleep and 12 hours of fasting and reclining, according to the American Council on Exercise.

RMR is typically 10 to 20 percent higher than BMR, according to the NASM. RELATED: 21 Tips for Weight Loss That Actually Work. Knowing your BMR or RMR can help you better determine your total daily energy expenditure in order to create a caloric deficit, defined as consuming fewer calories each day than you burn for energy.

A caloric deficit is required to lose weight. But because most people do not have access to state-of-the-art labs that are required to determine BMR, equations are often used to make approximations. The easiest way to measure your metabolic rate is to use an online calculator.

You can find many calculators online, and all use varying equations. The commonly used metabolic equation, called the Harris and Benedict equation, was first designed in and updated in While it was intended to estimate BMR, it actually estimates RMR, according to the NASM.

It uses height, weight, biological sex, and age to determine RMR and is based on average lean mass levels. The Mifflin-St Jeor equation is another equation that uses the same variables but may be more accurate, Church says.

Other metabolic equations, such the Cunningham equation, use your total levels of lean body mass, which is a primary determiner of BMR and therefore RMR. Calipers and smart scales are two popular at-home options, while the most accurate measures are performed in professional and laboratory settings.
