Our body responds to a number of different processes. One is the transformation of the food we eat into energy.
When food is converted into fat instead of oxidized and transformed into energy, get fat.
This situation is due to the inability of the body to burn fats that accumulate in the tissues mainly by inadequate nutrition, but also by a malfunctioning metabolism.
In this sense, a balanced diet designed not to accumulate fat in the tissues need to control the number of calories you eat, but above all to facilitate as far as possible the burning of fat.
