What you need to know about your metabolism

Be the first to know!


The set of processes that we include under the concept of metabolism is vital for life itself. And not only in human beings, but in all living creatures. Even if we simplify it by relating it to gaining or losing weight, it is much more. Therefore, we are going to explain everything you need to know about metabolic processes.

What is metabolism?

This is the name given to the set of chemical reactions that take place in the cells of our body and whose purpose is to transform the nutrients we ingest into vital energy. In other words, into the fuel your body needs for everything it does, from walking to growing to moving.

After you consume a food and it reaches your digestive system, organic molecules called enzymes are responsible for kicking off the metabolic process. They transform proteins into amino acids, carbohydrates into simple sugars such as glucose, and fats into fatty acids.

These substances are then absorbed by the blood, which carries them to the cells. Once inside the cells, another process begins in which enzymes, different from the previous ones, start new chemical reactions to metabolize these substances.

Through this whole process, energy is released and our body uses it in two ways:

  • To create and store body tissue.
  • To break down these tissues and take advantage of their previously stored energy.

Depending on which process is carried out, we’re looking at two metabolic processes:

  •  Anabolism or the constructive metabolic process. During this process, certain small, simple molecules are modified to create larger, more complex molecules made up of carbohydrates, fats and proteins. It is therefore concerned with creating and storing: this process develops new cells that strengthen body tissues and produces energy that is stored as a reserve for the future.
  • Catabolism or the destructive metabolic process. In contrast to the previous process, in this one, cells break down large molecules into smaller ones. The energy they produce is used by our body for its daily maintenance. For example, to move or to warm up. The waste generated in this process is, in turn, eliminated by the excretory tract.

Calculating your basal metabolic rate

Linked to all of these bodily reactions, another fundamental concept is the basal metabolic rate (BMR). This name is given to the minimum amount of energy needed by a human being at rest to carry out the basic vital functions of the body. For example, when we breathe or regulate our temperature.

It is a parameter that changes from one person to another according to their height, age, sex and weight. It is worked out, amongst other things, to help us when losing weight, since thanks to it, we can figure out how many calories our body needs. But it can also be used to detect metabolic problems and other diseases.

 It is calculated by indirect calorimetry. We assume that 208 milliliters of oxygen are needed to burn one calorie. By analyzing the amount of air exhaled and the oxygen and carbon dioxide it contains, we know the energy expenditure a person needs for basic vital functions.

Speed up metabolism

Metabolic training

On the basis of the basal metabolic rate, so-called metabolic training was created. It consists of performing a series of drills with few rest periods in between. In this way, we optimize calorie burning by increasing the metabolic rate during and after training.

These exercises involve you using a lot of body parts, so they require a lot of energy expenditure. They are anaerobic and high intensity, which consumes a lot of calories. From all this, you’ll have figured out that it’s a really tough, exhausting type of training.

Electro-stimulation as a complement to metabolic training

According to what we have just explained, metabolic training involves numerous physical and biochemical processes that occur in our body. In addition, it requires performing exercises dynamically, not statically. The short, but intense bursts of exercise are followed by pauses that help to improve the blood supply to muscles and tissues. This means that it accelerates metabolic function.

And this leads us to electro-stimulation as a complement to metabolic training. Popularly known as EMS (Electrical Muscle Stimulation), at Wiemspro we are one of the leading specialists in our country and our suits are perfect for your gym, physiotherapy center or beauty salon.

In any case, electro-stimulation is not a substitute for training, but it is the perfect complement to it. It consists of giving the muscles mini electric shocks, which come from special electro-stimulation machines. To do this, a few electrodes are placed on the muscles you want to stimulate. These small discharges mimic the impulses of the central nervous system and intensify muscle contraction.

In this way, the muscles work harder and thus enhance the metabolic training that we described earlier. All this arms you with a series of advantages among which stand out:

  • You can reduce your training time while doing the same exercise.
  • Activation of the deepest layers of muscle. The electrical impulses reach them better than conventional training.
  • Increase in calorie consumption and the elimination of toxins. Studies claim that your metabolism remains activated for up to 72 hours after training.
  • It contributes to the recovery of certain muscle injuries and even to the improvement of certain musculoskeletal illnesses such as atrophy. It also helps to strengthen muscles in terms of both their strength and endurance.
  • It increases blood circulation as well as lymphatic drainage. In turn, this improves vascularization and capillarization of the body.
  • It reduces injuries. It strengthens the muscles and their resistance, causing their fibers to better withstand workouts.

However, despite all the advantages EMS can offer. There are also cases where it is not recommended to use electro-stimulation, for example, pregnant women, people with pacemakers, or those suffering from epilepsy should not use it. The electrodes must not be placed over open wounds or on the neck or spine.

Metabolism and electrostimulation

Foods that speed up metabolism

On the other hand, metabolic training, with or without electro-stimulation, requires a lot of intensity. Therefore, it is advisable to balance out your effort with a rich diet and the consumption of foods that accelerate metabolic functioning. In general, these meals should include six optimal nutrient groups: water, protein, fat, vitamins, minerals and carbohydrates.

Regarding the latter, they are not recommended before or during training. But, outside of those times, they are highly recommended. The best are those contained in fruit, mushrooms and vegetables (carrots, peppers, eggplant, tomatoes and lettuce, for example).

As for proteins, we advise you combine animal and vegetable proteins. For example, nuts, turkey, chicken, eggs or fish, especially oily fish, which also contains omega-3. These and other sources or protein are also rich in vitamins such as B12, C or B1 and also in minerals such as magnesium or iron.

These foods are also highly recommended for accelerating your metabolism: lentils and other legumes, spicy foods, all kinds of fruits and drinks such as natural juices, green tea and coffee, which are also rich in antioxidants. With all of them you will optimize your metabolic exercises.

Conditions that affect metabolism

On the other hand, there are many conditions that can affect these metabolic processes that are fundamental to health. Among the most important of these is hypertension, which can also lead to other serious illnesses. 

These processes are also harmed by hypothyroidism. Thyroxine, the hormone produced by the thyroid gland, plays an essential role in metabolic processes. And with this condition, very little of it is made by the body. If you suffer from it, you’ll have symptoms such as fatigue, weight gain and constipation.

Conversely, hyperthyroidism damages the metabolic processes. As its name suggests, it is the opposite to the previous illness, since it relates to the thyroid producing too much thyroxine, . Among the symptoms that may make you think you suffer from it is unwarranted weight loss.

But perhaps the illness that most affects metabolic processes is diabetes, both type 1 and type 2. In the first type, the pancreas does not produce enough insulin, which is also necessary for these processes. Type 2 diabetes occurs when the body does not respond to insulin correctly. In other words, it shows resistance to it.

Finally, there are some congenital diseases that also affect the metabolism. Mainly they are galactosemia, which prevents assimilation of the sugar enzyme and phenylketonuria, which is when the enzyme responsible for breaking down the amino acid phenylalanine does not respond well. Metabolizing the latter is essential for growth and for producing proteins.
