Counting calories by itself is not always enough to lose weight. Many doctors today argue that what you eat matters much more. For this reason, your BMR might not give you the full context you need to understand what lifestyle changes you can make to achieve weight loss. The final number is approximately how many calories you need on a daily basis to maintain your weight.

Of course, this is an estimate. According to a study , the formula would be more accurate if it included body composition, weight history, and other factors that have been shown to affect BMR. 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.

The basal metabolic rate BMR is the amount of energy needed while resting in a temperate environment when the digestive system is inactive.

Likewise, depriving yourself of food in hopes of losing weight also decreases your BMR, a foil to your intentions. Howevera regular routine of cardiovascular exercise can increase your BMR, improving your health and fitness when your body's ability to burn energy gradually slows down. Once you know your BMR, you can calculate your Daily Calorie Needs based on your activity level using the Harris Benedict Equation. The original harris-benedict formula is one of the most used formulas on the internet to calculate your daily energy needs, however it is also one of the least accurate.

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.

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.

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.

Am J Clin Nutr ; US units metric units other units. Results unit:. Calories Kilojoules. BMR estimation formula:. Both BMR and RMR indicate the number of calories a person burns at rest. This information could be helpful for a person who is trying to manage their weight. If a person is trying to lose weight, calculating their BMR or RMR could help them figure out how many calories to cut out each day.

In some cases, this may mean consuming only enough calories to support essential life functions. Alternatively, if a person wants to gain weight, they could use their BMR or RMR calculation to work out how many extra calories to consume each day.

The total number of calories necessary to sustain basic life functions varies from person to person. The U. Dietary Guidelines for provides the following general guidelines on daily calorie intake for men and women:. The guidelines indicate that as a person ages, their BMR will generally decrease.

This means that they will require fewer calories than when they were younger. In general, a less active person will need fewer calories than a person who exercises regularly.

Of these factors, the only two that a person can potentially change are their body composition and their weight. A person can, therefore, alter their BMR and RMR by decreasing weight from fat and increasing lean muscle mass.

To achieve this, a person can try the following:. BMR estimates the minimum calories a person needs in order to sustain their basic life functions during a state of rest. A person can only receive an accurate BMR estimate in a well-controlled clinical setting.

RMR also estimates how many calories a person burns at rest. The testing requirements for estimating RMR are less strict than those for BMR.

Both BMR and RMR estimates may be helpful for people who are trying to manage their weight. They can indicate how many calories a person should be consuming daily to achieve their weight goals. Equations and online calculators can give a reasonable estimate of RMR.
