Losing Weight

How Do You Lose Weight, Even?


Though many fad diets have taken priority spots in people’s lives, fat loss is mainly about one specific principle, called “Eating in a caloric deficit”.


Your body requires a certain amount of energy to maintain its physiological processes and mass in space.


That amount of energy depends on the following factors:

  1. Gender

  2. Age

  3. Height

  4. Weight

  5. Non-training activity

  6. Training activity

  7. Food intake


If you consume more energy from food than your body needs to maintain its weight, you will progressively gain weight.


On the other hand, if you consume LESS energy from food than your body needs to maintain its weight, you will LOSE fat.


It’s quite simple and there is no way around it! Every fad diet that makes you lose weight does so not because of the diet itself, but because of the caloric deficit that it helps you establish.


But Where Does Lost Fat Go?


When you’re in a deficit of energy, your body uses its energy deposits (fat) to compensate for that deficit.


That is to say that during fat loss, your body actually burns off the fat in order to use it for a variety of functions.


When oxidized (burned with the help of oxygen), fat leaves the body in the form of carbon dioxide and water!


That is to say that the two main “exhausts” for lost fat, are:


  1. The lungs

  2. The urinary system


In other words, when you lose fat, you exhale the carbon dioxide and then the water gets into your circulation, until it leaves the body as sweat and urine.
