Our body is always not only in constant movement, but it is always working, and precisely so that all those chemical reactions that occur between cells and allow us to do all the activities that we carry out daily, our body spends a certain amount of kilocalories, which we take from food.
This means that we depend on the energy contained in food to survive, since if it were not for these we would not be able to continue living.
Usually this energy is expressed in calories, which means the amount of energy necessary to raise the temperature of one kilogram of water by 1º, which is why it is much more correct to speak of kilocalories.
Food calories
Foods tend to be divided into three types depending on the different and different nutrients they provide, which are: carbohydrates, proteins and fats.
In this case, both carbohydrates and proteins tend to provide about 4 calories per gram, while as we can imagine, fats reach 9 calories per gram. And it is precisely for this reason, and as many exerts defend, the ideal is that fats and carbohydrates provide us with 30 and 55% of our daily energy, respectively.
Why do we get fat when we eat too many calories?
They say that energy is neither created nor destroyed, but transformed. It is for this main reason that, if every day we eat an amount of food that tends to offer more energy than what we expend, we tend to start gaining weight.
This means that the best way to lose weight is to convert excess energy into heat so that it is eliminated, and we achieve this by exercising daily and staying active.
