Basal Metabolic Rate
The concept of basal metabolism, known as metabolism, in which the body provides energy without movement, that is, without physical movement, should be known, especially to people who are trying to lose weight and want to lose weight. Metabolism refers to a series of chemical processes that convert consumed nutrients into energy to keep you alive. Basal metabolism is the energy that occurs when you are not doing anything. “How is the basal metabolic rate calculated?“ before moving on to the question and details of "What is basal metabolism?" let's answer his question.
What is Basal Metabolism?
The basal metabolic rate (BMR) refers to the basic or minimal amount of energy that the body expends to survive at rest. Being awake and in a small state of motion does not carry the energy that is needed. During BMD, which is the total number of calories needed for the body to maintain its life, basic functions such as breathing, cell production, food processing, protein synthesis and ion transport take place. The brain, kidneys, liver and heart, the main organs of the body, account for half of the energy burned while at rest, while fat, the digestive system and especially muscles are responsible for the remaining energy.
Often the basal metabolic rate is confused with the resting metabolic rate. The separation of these two concepts, which are similar, can be explained as follows:
Basal Metabolic Rate: It is the amount of energy required to perform the basic functions of the body (respiration, cell production, circulation). In short, it is the energy that the body spends even while sleeping. The body always needs energy to have the right amount of fluid and essential substances. For example, muscles and nerves cannot function without a certain amount sodium and potassium. The basal metabolic rate can be calculated most accurately in a laboratory setting. There is also a formula that roughly calculates the BMR.
Resting Metabolic Rate: This is the amount of calories the body burns while resting. The resting metabolic rate is measured after a night's sleep, most often in the morning before breakfast or before doing a workout. It also includes daily movements such as digestion at a resting metabolic rate and dressing outside of exercise, the movement of eating.
Factors Affecting the Basal Metabolic Rate
Since the BMR is largely based on involuntary functions such as blood pumping and breathing, your daily amount of activity does not affect this speed much. However, there are some factors that affect the basal metabolic rate. Genetics plays an important role here. Some genes have a faster metabolic rate.
increases the BMR. Muscles spend 3 times more energy than fat, even in a state of sleep. Therefore, the ratio of muscle to fat changes the metabolic rate. In other words, the more muscle mass you, the more calories you will spend while resting.
Again, age is an important factor. With the progression of age, in parallel with the decreasing muscle mass, the metabolic rate also slows down. When you don't consume enough calories to meet your minimum energy needs, your metabolic rate drops by 30 percent.
Fever, even an increase of 0.5 above normal body temperature increases the metabolic rate by 7 percent.
If the thyroid hormone is not secreted properly, the metabolic rate may decrease by 30-40 percent.
How is the Basal Metabolic Rate Calculated?
The basal metabolic rate, which is calculated depending on height, weight and age, actually gives more of an estimate. Because it is only possible to calculate BMR in the healthiest way in the laboratory environment. BMR, calculated in a special environment with special equipment, gives the right result with a good night's sleep and fasting. Due to a strict diet and muscle mass, the metabolic rate is affected. Muscle mass can be built and maintained with activities such as weight lifting, sit-ups and push-ups, climbing stairs.
The Difference between Metabolic Rate and Basal Metabolic Rate
The basal metabolic rate accounts for 70 percent of the calories used by the body. The total amount of energy burned, in addition to the basal metabolic rate, your level of physical activity is determined by the calories burned when digesting food and absorbing nutrients by the body. That is, the metabolic rate is the energy consumption, which is also measured when you are physically on the move.
