What is your body type ?

April 7, 2019

We all have a friend or loved one who eats McDonald's every day and gets chocolate bars and sweets during the day. And despite this huge daily caloric intake, he remains skinny and does not take a kilogram of fat! In contrast, we all have a friend, a bit chubby or overweight, who every time he eats a caloric dish will gain weight.

The difference between these 2 friends? It's their metabolism.

What is metabolism?

Metabolism is a set of chemical reactions that take place within our body, to make our organs work. In nutrition: it is the capacity of our organism to transform what we eat into energy for the good functioning of our body.

Metabolism consists of two opposing mechanisms:

  • ** catabolism **: it allows to extract energy from nutrients, by degradation of energy molecules (carbohydrates, lipids, proteins) to use as energy or building blocks of cells.
  • ** anabolism **: it allows to synthesize the constituents necessary for the structure and the proper functioning of cells and muscles.

When it comes to burning calories, we must also take into account the two types of metabolism that our body contains: basal metabolism and metabolism in activity.

Basal metabolism

Basal metabolism is the set of reactions that keep the body alive. It helps to ensure breathing, heartbeat, brain nutrition, body temperature, digestion ...

Basal metabolism depends on many factors:

  • size ;
  • the weight ;
  • age;
  • the morphotype (see definition below);
  • sex

Our daily caloric requirement is usually around 1,200 to 2,000 kilocalories, to be provided by the diet. The surplus kilocalories consumed are then stored or must be eliminated by physical activity. In case of dietary deficiency (diet too severe), the basal metabolism changes. He learns to consume less and store more, resulting in greater weight gain at the end of the diet.

The metabolism in activity

The metabolism in activity corresponds to the increase of the energy requirement, necessary for the good functioning of the body during the physical exercise. Additional energy is consumed by the muscles in activity, but this energy depends on the intensity and duration of the activity.

The different types of morphotypes

In order to lose weight effectively and especially not to take it back, it is important to know its morphotype.

What is a morphotype?

A morphotype is a physical, genetic characteristic that defines the morphology (the appearance, depending on its skeleton) of an individual, but also its character and metabolism (fast, slow, ...).

According to their morphotype, some people will be tall, slender, with long muscles, while others will have a more stocky profile with rounder muscles. In the same way, some people remain more easily thin whatever their diet, while others will have all the trouble in the world to lose a few pounds.

There are three types of morphology: the ectomorphic, endomorphous and mesomorphic type. Each morphotype has specific physical characteristics whose origin is genetic.


The ectomorph has a very fast metabolism, which instantly burns fat. It's hard for him to gain weight. His figure is rather slim and slender with narrow shoulders. The ectomorph has long limbs, and is often larger. It has the finest skeleton of the 3 morphotypes. For these reasons, the ectomorph is thin or lean. Its rapid metabolism is often associated with a nervous temperament.

The mesomorph

The mesomorphic has the best metabolism. He has a large skeleton and a naturally muscular body. His body is conducive to bodybuilding, naturally endowed with a muscular physique, the mesomorph generally presents a bust in V. This one absorbs the calories better than the ectomorph, without assimilating them in fat like the sleepy one. On the personality side, the mesomorph has a fairly energetic and lively temperament. They are considered brave, but can also be authoritarian, sometimes aggressive and more risk-averse than others.

The endomorph

Smaller and stocky, an endormorphic creature often has a greater tendency to develop a certain body build and store fat. The sleeper will often seek to lose his extra pounds, his characteristic of accumulator fat quickly generating an overweight. Its metabolism is characterized as slow because its metabolism has trouble burning fat. The dormant is conducive to muscle gain, it will develop brute force faster than any other morphotype. If he learns the appropriate exercises, he will become the strongest of the three morphotypes. Of a rather sociable and jovial temperament, endomorphs are often quite extroverted and make friends easily.
