How is maturation related to increases in body fat ?

Explanation:

According to an article published by National Center for Biotechnology Information (NCBI), early maturation is associated with early body weight and greater height. This gained weight is related with body fat because as more mature the body is, more fat is needed, because that's the energy source to fulfil biological functions.

However, there is a specific period where this direct relation is more significant, from childhood to early adulthood, that's why the research was done in teen agers. During this period, the human body uses more energy, which means that more calories is needed, and more fat, this is why during this ages teenagers tend to eat a lot.

In addition, the sexual activity also is related with this body fat increases. Once teenagers are sexually active, their body will demand more energy to fulfil reproductive activities inside the body.
