What is metabolism?

Metabolism, to put it simply, is the amount of energy or calories than our body burns to maintain itself. In activities that can be indulging in, whether eating, drinking, sleeping or walking, our metabolism is constantly engaged in burning calories to keep us going. In the energy or calories that comes from the food we eat.

There are many factors that influence our metabolism of the body, from our genes to the composition of the different bodies, the nature of the food we eat and what kind of activity we do to those who burn calories. Some people simplify the meaning of metabolism and concluded that the metabolism is the one that affects how we gain or weight loss.

If the engine of a locomotive that runs on fuel, the human body also needs fuel in the form of food and nutrients. Without fuel, the engine stops, as well, our metabolic engine (our body) will also cease to function without food.

Beyond converting nutrients into energy, our metabolic system is also responsible for a multitude of other functions: it helps to digest the food we eat, absorbs the nutrients of the goods in the cells, breaks down nutrients and eliminates harmful toxins from the body.

There are particular proteins that control various chemical reactions of metabolism. Each of these chemical reactions are linked to various body functions. The pace at which takes place metabolism are controlled by a set of hormones produced by a system called the endocrine system in our body.

For example, thyroxine is a hormone produced by the thyroid gland happy. It plays a crucial role in determining the speed at which chemical reactions occur in the body.

Metabolism can be divided into two components: anabolism and catabolism. Anabolisme, as its name suggests, is the creation or constructive role in metabolism, which is responsible for the development, growth and storage functions.

The growth of new cells, tissues maintenance and fat storage for future use are some of anabolic functions. The catabolic role in the metabolism is the destroyer, which is the process responsible for the energy needed for all cellular activities.

metabolic biochemical process involves calories, which are generated by the carbohydrates, protein and fat in our diet, combined with oxygen to produce energy our body needs to function. Thus, the total energy expenditure is the amount of calories the body burns every day.
Even when we sleep, the process of metabolism is at work, as the body needs energy to perform basic functions such as breathing, blood circulation, growth and repair of cells, and maintaining the hormonal balance.

Most of the energy used per day, sometimes two thirds to three quarters of the total number of calories, is typically the basal metabolic rate of an individual. Under normal circumstances, the body's basic energy requirement for the food processing is stable and does not change radically. Weight gain is a direct result of the imbalance in energy costs - more calories than to burn calories.

Metabolism is a process without which all living organisms die. Knowing how to take care of the body resulting in a stable metabolism, which is essential for good health.
