The basal energy expenditure is the energy needed to maintain vital physiological functions. Represents at least two thirds of total energy consumption with the exception of persons performing intense physical activity. The basal energy expenditure will depend on the age, size and physiological characteristics of the person .. You can estimate basal energy expenditure for different age and sex from body weight using equations that give us a consistent theoretical value in reference to various studies undertaken

After the basal metabolism, physical activity represents the second factor of energy expenditure. In rich countries or developed physical activity related to work has decreased recommend is important for its positive health characteristics and quality of life for all of us. It is relevant considering the energy requirements that result from physical activity.

Energy expenditure also increases after eating. This increase is going to depend on the amount of calories you consume and feed composition. This expenditure of energy we know as the thermic effect of food. The thermic effect of food is going to be higher for smaller proteins and for carbohydrates and fats.
