Don’t have the basics?

Just as a car needs gas, our body needs energy to function and perform daily tasks.

This energy is measured in calories.

Energy consumption covers two basic needs

1. Basic metabolism
This is the minimum amount of energy the body needs to maintain vital functions (such as lying down all day without physical activity), like a static car with the engine running.

2. Physical activity:
For a seated person, “walk, take public transport, climb stairs, etc. “

For the active: 1 hour of running, 1 hour of training with weights or hiking in the mountains »

PS: There are actually other energy needs such as digestion or thermogenesis, I keep it to a higher level

The sum of the basic metabolism (MB) “remember when you are not moving” and other energy needs (DEJ) daily energy expenditure “when your body is moving” gives the total metabolism, which therefore represents the total energy that we pass. in one day. Something like the total consumption of a car in a day, between stops with red lights and accelerations on the highway.

The basic metabolism varies greatly from one person to another: it depends on age, gender, weight. For example, it can be twice as much for a growing teenager as it is for an adult!

Of course, to address this cost, there must be an energy supply.
How is this energy provided to us?

This energy is the food that brings us. They are our calorie suppliers in the form of three types of macronutrients: proteins, carbohydrates and fats.

To find out how many calories a food brings us (and therefore energy), it is helpful to know that:

1gr protein = 4kcal

1gr carbohydrate = 4kcal

1gr of lipid = 9kcal

1gr ethanol = 7kcal alcohol (my precious)

!!!! It finally helps to understand that no food makes you fat or thin.

You gain weight when you eat more calories than you need (that is, more than your total metabolism or your daily energy expenditure).

You get thinner when you eat fewer calories than you need

Act on the energy balance:

There are therefore two levers for tilting the scale to one side or the other:

Acting in our physical activities.
Acting on the calorie intake provided by our diet.

In short: Our bodies need energy to live and this energy is provided by food in the form of calories.
Diet laws can be summed up in a simple golden rule:

If my recruitment is greater than my needs. Then I go fat
If my recruitment is lower than my needs. So I get thinner

It is so simple! If you are gaining fat, eat more than you need. and if you can’t get fat, you don’t eat enough …

But in addition to the quantitative aspect of food, we must pay special attention to its qualitative aspect, which has a direct impact on health.

What foods to choose? Why eat enough protein? How to balance fat intake? Which Carbohydrates Are Better? Why not miss out on vitamins and minerals?

So many basic questions that will be the subject of the next article …
