Basal metabolic rate (BMR) is the rate of energy expenditure per unit time by endothermic animals at rest. … Metabolism comprises the processes that the body needs to function. Basal metabolic rate is the amount of energy per unit of time that a person needs to keep the body functioning at rest.
What is basal metabolism simple definition?
: the turnover of energy in a fasting and resting organism using energy solely to maintain vital cellular activity, respiration, and circulation as measured by the basal metabolic rate.
What is basal metabolism in nutrition?
Basal metabolism (HeE) is the result of chemical change that occurs in the cells of an animal in the fasting and resting state using just enough energy to maintain vital cellular activity, respiration, and circulation.
What is an example of basal metabolism?
Your basal metabolic rate (BMR) is defined as the rate at which your body uses energy when you are resting in order to keep vital functions going such as breathing. The rate at which your body uses energy to breath and stay warm is an example of your basal metabolic rate.
What is the right definition of BMR?
the rate at which energy is expended in a basal condition, calculated as calories per hour per square meter of body surface and compared with a normal standard expressed as the percentage above or below the amount of oxygen normally used at rest, −15 to +5 percent being considered normal. Abbreviation: BMR.
Why is basal metabolism important?
Knowing your Basal Metabolic Rate is important whether you want to maintain your weight, lose weight, or even gain weight. Your BMR can help determine what number of calories you should be eating in order to meet your goals. If you want to lose weight, you will need to eat less than your BMR (or maintenance calories).
What is basal metabolism used for?
The basal metabolic rate (BMR) has a long history in the evaluation of thyroid function. It measures oxygen consumption under basal conditions of overnight fast and rest from mental and physical exertion.
What are the factors that affect basal metabolism?
Here are ten factors that affect BMR and metabolism:
- Here are ten factors that affect BMR and metabolism:
- Muscle mass. The amount of muscle tissue on your body. …
- Age. As you get older, your metabolic rate generally slows. …
- Body size. …
- Gender. …
- Genetics. …
- Physical activity. …
- Hormonal factors.
What is metabolism process?
Metabolism (pronounced: meh-TAB-uh-liz-um) is the chemical reactions in the body’s cells that change food into energy. … Specific proteins in the body control the chemical reactions of metabolism. Thousands of metabolic reactions happen at the same time — all regulated by the body — to keep our cells healthy and working.
How is basal metabolism measured?
The BMR is usually determined by indirect calorimetry by measuring Q O 2 , the rate of oxygen consumption. The resting energy expenditure (REE) differs from the BMR in that the determination of the REE does not require fasting for 12 hours.
How do I lower my basal metabolic rate?
10 Easy Ways to Boost Your Metabolism (Backed by Science)

What is BMR in your own words?
Basal Metabolic Rate, also known as BMR, is the amount of energy your body burns at rest on a daily basis. In other words: It is the number of calories required to keep your body function while you are not doing any physical activities.
Who has a higher metabolic rate?
Men tend to have a higher metabolism than women, but genes, body size, and age all play a role in how the body gains fat and loses muscle.
Is a high BMR good?
“A higher BMR means you need to burn more calories to sustain yourself throughout the day. A lower BMR means your metabolism is slower. Ultimately, leading a healthy lifestyle, exercising, and eating well is what’s important,” said Trentacosta.
