What is Metabolism?

metabolismWhat is Metabolism?


Weight management is all about a person’s metabolic process and the metabolic rate. A slowdown in the metabolic rate is a key contributor for the Lexapro weight gain. The metabolic rate is different in every single person. Metabolism is the process of burning up calories within your body which actually occurs naturally even when you are not exercising, therefore even when we are asleep. If the metabolism is disturbed by whatever factors the result will be changes of weight that are regardless of what or how much you eat.


The metabolic rate is defined as the rate at which the body burns up calories. Our muscle groups are in charge of burning calories even though we are not carrying out any physical activity. Long lasting weight reduction can be accomplished through improving the metabolism.


How is the Metabolism determined?


There are metabolic tests known as direct and indirect calorimetry. These kinds of tests measure the energy in the form of heat or the amount of oxygen consumed over a period of time. The objective of the test is to determine the RMR or Resting Metabolic Rate of a person. The RMR as well as your entire metabolic process change over time, so as to monitor your current RMR you will need to re-perform the test after a while. Changes in lifestyle directly impact the result. The RMR is the overall rate of how many calories are consumed thru activities as well as inactive periods.

Factors influencing the Metabolic Rate


There are numerous components that have an effect on the metabolic rate and their effect is unique for every individual. The age, gender, amount of muscles in comparison to the amount of fat, and also the quantity of physical exercise are the main determining factors for the rate of metabolism. These items make our body shapes distinctive from one another. It does not signify that a slender person is so picky with regards to food. Additionally, there are cases of genetic as well as hormonal aspects that affect the metabolism. For this reason we are wondering why some individuals can eat a whole lot, but nevertheless remain slim.




One of the factors is age. Once we become older, the muscles degrade leading to a reduced RMR. Consequently, growing older is associated with weight gain. This is due to the fact that younger people possess more active human growth hormones. Actually, studies show that human growth hormones should not be prescribed for older people, because they will probably experience negative consequences.




Men have a higher metabolic rate than women due to the testosterone. As you may know testosterone is in charge of all the “masculine matters” in men’s physiological features. It also involves the development of muscles. Naturally guys are born with more muscles compared to girls. As a result, they have higher metabolic rates compared to women; they have estrogen as well as progesterone as sex hormones.


Females have an increased metabolic rate when they are expecting a baby and when they are breastfeeding a baby. However, the rate drops again once they menopause. In order for them to sustain higher metabolic rates, regular physical exercise might be very beneficial. Doing this will grow the volume of muscles and hence also improve the metabolic rate.


Physical Exercise


Exercise can boost the metabolic process; however, the point is that a person has to do exercises that are appropriate and effective for the particular body type. Experts say that muscles are the most significant factor in a person’s metabolic rate. More muscular tissues imply a higher rate of metabolism. As a result, individuals with more active muscular tissues shed weight quicker as opposed to those who do not. There has to be a balance between the food consumption and the physical work you do. Regular physical exercise will certainly enhance the metabolism.

Eating Habits


Obviously, the foods we consume are among the most important factors. The selection of food actually differs based on someone’s way of life. Many rather busy individuals are into junk food. This turns them to unhealthy eating providing them with higher calorie consumption as opposed to those who are into healthy food choices. More calories along with a reduced metabolic process necessarily mean much more weight gain.


Water consumption is another aspect. The body makes use of water in various processes. Consequently, individuals who stay hydrated and drink a lot of water hold the possibility to have a quicker metabolic process.




Stress is in fact among the lesser influential of all the factors. Many stressed people tend to be more prone to a lower metabolic rate. Stress interferes with several regular processes of the body. This causes them to gain more weight and faster compared to those who have less stress in their lives. Additionally, it is factual that people eat far more when they are under stress or frustrated. For them eating functions as the catharsis.
