However, to get the most accurate idea is to have a trained technician perform indirect calorimetry, which is a study of your metabolism. This test measures how much oxygen O2 you take in and how much carbon dioxide CO2 you take out when you breathe.
The quantity of these gases varies depending on how your body metabolizes different macronutrients such as carbs, fats, and protein for energy.
Of these factors, you can take steps to change your weight and body composition. So if you want to change your BMR, your first step should be to increase muscle. For example, a study suggests that resistance training is an effective means of boosting BMR levels among a group of inactive adult women.
Understanding your BMR, your typical activity level, and the amount of calories you need daily to maintain your weight are important ways for you to actively participate in your physical health. Whether you need to gain weight, maintain your current weight, or lose weight, calculating your BMR is a good place to start.

Resting metabolic rate, or RMR for short, is the rate at which the body burns energy in a relaxed, but not fully inactive state. It is also sometimes defined as resting energy expenditure, or REE. BMR measurements must meet total physiological equilibrium while RMR conditions of measurement can be altered and defined by contextual limitations.
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. Therefore, all BMR calculations, even using the most precise methods through specialists, will not be perfectly accurate in their measurements.
Not all human bodily functions are well understood just yet, so calculating total daily energy expenditure TDEE derived from BMR estimates are just that, estimates.
When working towards any sort of health or fitness goal, BMR can aid in laying down the foundations, but from there on, it has little else to offer.
A calculated BMR and thus TDEE may result in unsatisfactory results because of their rough estimates, but maintaining a daily journal of exercise, food consumption, etc. Tracking progress in said journal and making adjustments over time as needed is generally the best indication of progress towards reaching personal goals.

Give Today. Other formulas exist which take into account lean body mass, two of which are the Katch—McArdle formula and Cunningham formula. The Katch—McArdle formula is used to predict resting daily energy expenditure RDEE.
where f is the body fat percentage. The basic metabolic rate varies between individuals. One study of adults representative of the population in Scotland reported basal metabolic rates from as low as 1, kilocalories 4, kJ per day to as high as 2, kilocalories 10, kJ ; with a mean BMR of 1, kilocalories 6, kJ per day.
This remaining difference was not explained by sex nor by differing tissue size of highly energetic organs such as the brain. A cross-sectional study of more than subjects in Europe and the US showed that once adjusted for differences in body composition lean and fat mass and age, BMR has fallen over the past 35 years.
For the BMR, most of the energy is consumed in maintaining fluid levels in tissues through osmoregulation , and only about one-tenth is consumed for mechanical work , such as digestion, heartbeat, and breathing.
What enables the Krebs cycle to perform metabolic changes to fats, carbohydrates, and proteins is energy, which can be defined as the ability or capacity to do work. The breakdown of large molecules into smaller molecules—associated with release of energy—is catabolism.
The building up process is termed anabolism. The breakdown of proteins into amino acids is an example of catabolism, while the formation of proteins from amino acids is an anabolic process.
Exergonic reactions are energy-releasing reactions and are generally catabolic. Endergonic reactions require energy and include anabolic reactions and the contraction of muscle. Metabolism is the total of all catabolic, exergonic, anabolic, endergonic reactions.
Adenosine triphosphate ATP is the intermediate molecule that drives the exergonic transfer of energy to switch to endergonic anabolic reactions used in muscle contraction. This is what causes muscles to work which can require a breakdown, and also to build in the rest period, which occurs during the strengthening phase associated with muscular contraction.
ATP is composed of adenine, a nitrogen containing base, ribose, a five carbon sugar collectively called adenosine , and three phosphate groups. ATP is a high energy molecule because it stores large amounts of energy in the chemical bonds of the two terminal phosphate groups.
The breaking of these chemical bonds in the Krebs Cycle provides the energy needed for muscular contraction. Because the ratio of hydrogen to oxygen atoms in all carbohydrates is always the same as that in water—that is, 2 to 1—all of the oxygen consumed by the cells is used to oxidize the carbon in the carbohydrate molecule to form carbon dioxide.
Consequently, during the complete oxidation of a glucose molecule, six molecules of carbon dioxide and six molecules of water are produced and six molecules of oxygen are consumed. Because the gas exchange in this reaction is equal, the respiratory quotient R. for carbohydrate is unity or 1.
The chemical composition for fats differs from that of carbohydrates in that fats contain considerably fewer oxygen atoms in proportion to atoms of carbon and hydrogen. When listed on nutritional information tables, fats are generally divided into six categories: total fats, saturated fatty acid , polyunsaturated fatty acid , monounsaturated fatty acid , dietary cholesterol , and trans fatty acid.
From a basal metabolic or resting metabolic perspective, more energy is needed to burn a saturated fatty acid than an unsaturated fatty acid. The fatty acid molecule is broken down and categorized based on the number of carbon atoms in its molecular structure. The chemical equation for metabolism of the twelve to sixteen carbon atoms in a saturated fatty acid molecule shows the difference between metabolism of carbohydrates and fatty acids.
Palmitic acid is a commonly studied example of the saturated fatty acid molecule. Proteins are composed of carbon, hydrogen, oxygen, and nitrogen arranged in a variety of ways to form a large combination of amino acids.
Unlike fat the body has no storage deposits of protein. All of it is contained in the body as important parts of tissues, blood hormones, and enzymes. The structural components of the body that contain these amino acids are continually undergoing a process of breakdown and replacement.
The respiratory quotient for protein metabolism can be demonstrated by the chemical equation for oxidation of albumin:. The reason this is important in the process of understanding protein metabolism is that the body can blend the three macronutrients and based on the mitochondrial density, a preferred ratio can be established which determines how much fuel is utilized in which packets for work accomplished by the muscles.
This process could severely degrade the protein structures needed to maintain survival such as contractile properties of proteins in the heart, cellular mitochondria, myoglobin storage, and metabolic enzymes within muscles.
The oxidative system aerobic is the primary source of ATP supplied to the body at rest and during low intensity activities and uses primarily carbohydrates and fats as substrates. Protein is not normally metabolized significantly, except during long term starvation and long bouts of exercise greater than 90 minutes.
Following the onset of activity, as the intensity of the exercise increases, there is a shift in substrate preference from fats to carbohydrates. Studies published in [31] and [32] indicate that the level of aerobic fitness of an individual does not have any correlation with the level of resting metabolism.
Both studies find that aerobic fitness levels do not improve the predictive power of fat free mass for resting metabolic rate.
When you consider time commitments against health benefits, aerobic training is the optimal mode of exercise for reducing fat mass and body mass as a primary consideration, resistance training is good as a secondary factor when aging and lean mass are a concern.
Resistance training causes injuries at a much higher rate than aerobic training. Resistance training if time is available is also helpful in post-exercise metabolism, but it is an adjunctive factor because the body needs to heal sufficiently between resistance training episodes, whereas with aerobic training, the body can accept this every day.
RMR and BMR are measurements of daily consumption of calories. Anaerobic exercise , such as weight lifting , builds additional muscle mass.
Muscle contributes to the fat-free mass of an individual and therefore effective results from anaerobic exercise will increase BMR. Even a substantial increase in muscle mass, say 5 kg, would make only a minor impact on BMR. In , Raymond Pearl proposed that longevity varies inversely with basal metabolic rate the "rate of living hypothesis".
Support for this hypothesis comes from the fact that mammals with larger body size have longer maximum life spans large animals do have higher total metabolic rates, but the metabolic rate at the cellular level is much lower, and the breathing rate and heartbeat are slower in larger animals and the fact that the longevity of fruit flies varies inversely with ambient temperature.
Calorie restriction and reduced thyroid hormone levels, both of which decrease the metabolic rate, have been associated with higher longevity in animals. However, the ratio of total daily energy expenditure to resting metabolic rate can vary between 1.
Animals also vary in the degree of coupling between oxidative phosphorylation and ATP production , the amount of saturated fat in mitochondrial membranes , the amount of DNA repair , and many other factors that affect maximum life span.
One problem with understanding the associations of lifespan and metabolism is that changes in metabolism are often confounded by other factors that may affect lifespan. For example under calorie restriction whole body metabolic rate goes down with increasing levels of restriction, but body temperature also follows the same pattern.
By manipulating the ambient temperature and exposure to wind it was shown in mice and hamsters that body temperature is a more important modulator of lifespan than metabolic rate.
In allometric scaling , maximum potential life span MPLS is directly related to metabolic rate MR , where MR is the recharge rate of a biomass made up of covalent bonds.
That biomass W is subjected to deterioration over time from thermodynamic, entropic pressure. Metabolism is essentially understood as redox coupling, and has nothing to do with thermogenesis.
Metabolic efficiency ME is then expressed as the efficiency of this coupling, a ratio of amperes [ clarification needed ] captured and used by biomass, to the amperes available for that purpose.
MR is measured in watts, W is measured in grams. The smaller W is to begin with, the more dramatic is the increase in MR as ME diminishes. All of the cells of an organism fit into this range, i. An MR made up of an organization of BMRs will be referred to as an FMR.
The antagonism between FMR and BMR is what marks the process of aging of biomass W in energetic terms. A person's metabolism varies with their physical condition and activity.
Weight training can have a longer impact on metabolism than aerobic training , but there are no known mathematical formulas that can exactly predict the length and duration of a raised metabolism from trophic changes with anabolic neuromuscular training.
A decrease in food intake will typically lower the metabolic rate as the body tries to conserve energy. The metabolic rate can be affected by some drugs, such as antithyroid agents , drugs used to treat hyperthyroidism , such as propylthiouracil and methimazole , bring the metabolic rate down to normal and restore euthyroidism.
The daily caloric need is the BMR value multiplied by a factor with a value between 1. In most situations, the BMR is estimated with equations summarized from statistical data.
The Harris-Benedict Equation was one of the earliest equations introduced. It was revised in to be more accurate and was used up until , when the Mifflin-St Jeor Equation was introduced. The Mifflin-St Jeor Equation has been shown to be more accurate than the revised Harris-Benedict Equation.
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.

Proper measurement requires ratf Body fluid balance set of criteria Metabolic rate be Metabolic rate. These Metabolic rate include being in a physically and psychologically undisturbed state and being in a thermally neutral environment while in the post- absorptive state i. It follows the same criteria as BMR, but requires the documentation of the temperature at which the metabolic rate was measured. This makes BMR a variant of standard metabolic rate measurement that excludes the temperature data, a practice that has led to problems in defining "standard" rates of metabolism for many mammals.

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.
These handheld devices are available in many health and fitness clubs, doctor offices, and weight-loss clinics. While the two are used interchangeably, there is a key difference in their definitions.

Join a fitness community that's over 2 million people strong! com's calculator uses the Harris-Benedict equation, which is considered by many experts to be the most accurate BMR calculation for most types of people. Here's how it works:. This will vary person by person. Since your basal metabolic rate is based largely on involuntary functions like breathing and pumping blood, changes in your day-to-day activity don't do much to raise or lower this number. However, increasing muscle mass does increase BMR, because muscle is metabolically "hungry" and it takes more energy to maintain more muscle. This means that when you have a lot of muscle mass, you'll burn more calories at rest. The overall number of calories your body uses on a daily basis is referred to as your "total daily energy expenditure" TDEE. It's determined based on your BMR as well as your activity level throughout the day. This varies significantly based on your activity level, age, and sex. You can use a TDEE calculator or calorie calculator to find this number to get a more specific result. Keep in mind, though, that it's impossible to know your exact TDEE, as your activity levels will change day to day, and the only way to get percent accurate BMR numbers is through laboratory testing. The term BMR is sometimes used synonymously with RMR, which stands for "resting metabolic rate. BMR and RMR numbers are typically close enough to be interchangeable, but if you're calculating your needs in order to gain or lose weight, pay attention to which number an equation calls for. If it's based on BMR, you can use the calculator above to get an estimate. If the equation uses RMR, use our RMR calculator , which will give you a slightly higher number. Once you use your BMR to determine your TDEE, you can make sure that the nutrition plan you follow is appropriate for your level of energy expenditure and that it isn't giving you too many or too few calories. Being armed with this knowledge, rather than guesstimating or blindly following a plan without scaling it to your individual needs, can make or break your muscle gains or fat loss. Once you have your BMR, it's time to take the same kind of strategic approach to the rest of your training and nutrition. These popular calculators can help you dial in your plan!
