Let’s clarify some concepts before starting:
What is a calorie?
Calorie is a unit of energy. The energy contained in food is expressed as calories.
How are the calories in food calculated?
This measurement is made in laboratories, through instruments called calorimeters.
Basically inside the calorimeter the food is burned and the energy released in the combustion is measured.
What is the theory of the energetic balance?
It is the dogma that has dominated the explanation about how we gain weight and how we lose weight.
It is an equation determined by the energy that enters our body (calories that enter: what we eat) and the energy that comes out (calories that come out: exercise, basal metabolism and other energy costs) Continue reading “Do we Have to Count Calories?”
