The calories problem

Comes the next question: how many calories I need to lose weight?

To know the number of calories needed, you must know what they are for our body.
Definition should be: the unit of energy extracted from food that our body uses for the activities it performs.

Besides the energy the body when it is carried out physical activities such as going to the gym, running, aerobics, body consumes calories for life processes (breathing, to digest food, to move from one point to another, but also for the correct functioning of internal organs).

If we refer only to the number of calories you get from food, it must be slightly lower than the daily requirement of calories, so that you allow the weakening, but not too low because in this situation your body will go into a state of crisis and everything gets messed up.
