When thinking about caloric expenditure, we automatically think of physical activity, after all, it is through them that we can increase our energy expenditure. However, our body is constantly expending energy in order to function and carry out its basic activities. In this sense, the brain is one of the organs that spends the most calories.

Energy we spend thinking
Did you know that the brain is the organ in the human body that uses the most energy? Only during basic activities such as breathing, digestion, among others, it spends an average of 20% of all the energy in our body. That is, approximately 400 calories. However, in children this expense can reach up to 60%.
But what about when we make more brain effort, like thinking, studying or working? In general, to carry out more complex activities, the brain does need more energy, as these activities deviate from the pattern it is used to working with. However, the energy expended in these activities is not much higher than normal day-to-day activities. As the brain is already responsible for countless functions in our body, it already works all the time, and although new and more complex things impact its activity, this impact is not so relevant.
On the energy expenditure of the human body
Speaking of energy expenditure, do you know what caloric expenditure is? It corresponds precisely to the total amount of calories you spend daily. In this sense, it is not just about caloric expenditure in physical activities, but how much energy is spent in total, even in basic body activities, such as those performed by the brain.
In addition, knowing how your caloric expenditure is something very complex, considering that it involves many factors. Among the issues that influence this, the main ones are gender, weight, age and the amount of physical effort made in the day, whether in domestic activities, working or physical exercises.
