Basal metabolism is usually the largest component of a person’s total caloric needs. An accurate BMR measurement requires that a person’s sympathetic nervous system be inactive, which means the person must be completely rested. The BMR is measured under very restrictive circumstances while awake. Having this information instead of guessing or blindly following a plan that doesn’t fit your needs can make or break your ability to gain muscle or lose fat. When you use your BMR to figure out your TDEE, you can make sure that your nutrition plan fits your level of energy use and doesn’t give you too many or too few calories. How can I use my BMR to lose fat or gain muscle? If the equation needs RMR, use our RMR calculator, which will give you a slightly higher number. If it’s based on BMR, you can use the calculator above to get a rough estimate. However, if you are trying to gain or lose weight, you should pay attention to which number an equation calls for. The term “BMR” is sometimes used in the same way as “RMR,” which stands for “resting metabolic rate.” The difference is that BMR only looks at how much energy it takes to breathe, circulate blood, and keep your body temperature stable when you are completely still, while RMR also looks at how much energy it takes to digest food and do daily tasks like getting dressed and lifting your fork to your mouth.īMR and RMR numbers are usually close enough that they can be used interchangeably. What’s the difference between BMR and RMR? Keep in mind, though, that you can’t know your exact TDEE because your activity level changes every day, and the only way to get 100% accurate BMR numbers is to get tested in a lab. To get a more accurate answer, you can use a TDEE calculator or calorie calculator to find this number. This depends a lot on how active you are, how old you are, and what gender you are. It’s based on your basal metabolic rate (BMR) and how active you are during the day. Your “total daily energy expenditure” (TDEE) is the number of calories your body uses in a day as a whole. This means that if you have a lot of muscle, you’ll burn more calories even when you’re not doing anything. But building more muscle does raise BMR because muscle is “hungry” for energy and it takes more energy to keep more muscle. Since most of your basal metabolic rate comes from things you can’t control, like breathing and pumping blood, day-to-day changes don’t have much effect on this number. Physical activity makes up about 20% of expenditure, and about 10% is used for the digestion of food, also known as thermogenesis. For most people, upwards of 70% of the total energy (calories) burned each day is due to maintenance. In such a state, energy will be used only to maintain vital organs, which include the heart, lungs, kidneys, nervous system, intestines, liver, lungs, sex organs, muscles, and skin. It is the equivalent of figuring out how much gas an idle car consumes while parked. The basal metabolic rate (BMR) is the amount of energy needed while resting in a temperate environment when the digestive system is inactive.
