Metabolism is the sum of all physical and chemical processes by which a living substance is formed and maintained and by which energy
is made available for use by the organism. In other words, it refers to the rate at which your body utilizes calories to meet energy demands.

The number of calories we burn while our body is at rest is known as the Basal Metabolic Rate or BMR.
As we age, the BMR rate falls down, thus, making it hard for the
body to burn calories, this explains why we tend to have difficulty
losing weight on our later age. There are so many factors that affect
metabolism; some may have positive effects while others have negative
effect. These factors tend to decrease or increase metabolic rate. How
does exercise, stress, and sleep affect metabolism?
Exercise, Stress And Lack Of Sleep Effects On Metabolism
- Exercise
Exercise is one way of improving the BMR rate as well as health and
fitness too. Exercise tends to increase BMR, therefore, making weight
loss faster. Some exercises may cause the body to continuously burn
calories at a higher rate even after the exercise is already finished.
Studies show that low-intensity exercises increase fat oxidation by
40%. This may imply that walking is better than running; this type of
exercises is more preferable rather than high-intensity exercises which
do not actually affect fat oxidation. And in addition, low-intensity
exercises cause lower possibility of musculoskeletal injuries.
- Stress
Another thing that affects metabolism is stress; it has either the
negative and positive impact. Have you noticed when people get
stressed, they tend to eat more or maybe the other way around?
Prolonged stress disrupts the digestive system. The stomach produces
excessive amounts of digestive acid that interferes with the normal
process of the digestive system.
Stressed persons are prone to peptic ulcers and other digestive
problems that are known to be causes of lowered metabolism rate. So
when a person is stressed, there is a tendency that he will pile up in
pounds because the body cant burn most of its calorie intake.
- Lack Of Sleep
How could someone who lacks sleep even attempt to exercise or to
work out intensely? Lack of sleep could reduce your BMR. Lack of sleep
affects the hormone levels in the body. As sleep decreases, the adrenal
gland produces more cortisol. Cortisol is a hormone that regulates
appetite, as its level increases, the person’s hunger raises too
despite being full.
