I have heard so many times the affirmation that a skinny person who never gains any weight no matter what she or he eats, has a better and faster metabolism.
In the following rows of this article I will give you a real theory based on real researches and studies (made by others), that proves otherwise.
In case you are interested in what I am about to say you should continue your reading. I have a personal satisfaction to demolish this myth so I have read many articles about it before I decided to share the gathered knowledge with you.
Generalities about metabolism
Even if you might not trust me on this, it seems that your metabolism is forced to work faster and burn more calories when you are fat, in order to help your body to preserve its vital functions.
As much food you ingest the body must work harder to digest it. This means that your metabolism must increase its speed. This was observed especially when people were resting, because this is the time when the metabolism enters into the scene and it must work for you.
As you might have noticed, when you keep a diet and after you lose quickly several kilos, you enter into a stagnation period. You might wonder why.
Well, when your body loses weight, your metabolism relaxes a bit and it stops burning so many calories because it does not have to. In order to continue the slimming process you should eat less and less calories so your metabolism will start running again.
