Body, energy consuming machine (II)
As explained in the previous issue, on this occasion, we will focus on the other factors that we must take into account to calculate the energy consumption of each one of us, analyzing body composition and physical exercise.
The human body in general is a machine composed of water, fat and muscles, which are our components. In any case, the proportion of these components is not the same in all cases and, for example, men have a higher amount of protein than women and a lower amount of fat (15% of the body in men and 25% in women).
As is logical, the energy needs vary: women need less energy because the metabolism of fats is slower and, on the contrary, the metabolism of proteins is faster, so men tend to have greater needs. This aspect is reflected in the following table: doing the same activity, it is clearly observed that women and men have different energy consumption.
As mentioned above, among the factors to take into account is daily activity. The type of work and physical exercise have a lot to do with our needs. As is known, a person working in the office burns fewer calories than a bricklayer. The choice of exercise that requires individual work is difficult, but the physical exercise that we can perform outside of it can be very variable and, in addition, can be chosen.
We have already said that women usually burn fewer calories, but if you are a sportsman, the woman will burn more calories than the guy who spends all day lying. There are, therefore, important biological laws, but our energy consumption, in a great grinding, we can choose it. Taking as a model the following table, you can calculate the activity carried out by each of you and the daily energy needs. And from there, tell us! News News News
- The toxicity of aluminium is a very widespread material. Acid rain, cosmetics, or water treatment plants have been mentioned as the cause of the increase in the amount of aluminum in the soil, so it can be considered directly related to development. Although to date its effects on the human body were unknown, the latest research has confirmed its direct influence on diseases of the nervous system and some kidney diseases.
- The importance of breakfast The summer season is ideal for quiet breakfasts. If it is a reinforced custom in previous months, we must keep it, since the first meal of the day serves to strengthen our machine. According to the old saying, breakfast should be like the one made by kings: freshly squeezed orange juice or substitute, milk with cereals, coffee with milk and toast with jam, biscuits… Sure everyone will have to do it according to their tastes, but the golden rule is that do not forget to have breakfast every day!
