You probably hear lots of tips here and there about losing weight. What to do, what not to do, etc.
I like to go back to the basics, the basics. Because it is by understanding things at the base that we can better understand the rest.It’s the same for weight loss. You cannot get expected weight loss results unless you know what the process entails.
A little physiology
The loss of body fat is directly related to metabolism.
People often hear about metabolism, but not many know what it is.
Metabolism is “the set of biochemical reactions catalyzed by appropriate enzymes and resulting in syntheses (anabolism) or degradation (catabolism) of biological molecules”. It is the set of “physical and chemical exchanges in the tissues through which a body is kept alive and its energy regenerated”.
The metabolism is in two parts: the anabolic which is the synthesis, the construction, and the catabolism which is the degradation, the disassimilation.
If we focus on adipose tissue, the one we want to lose, we must understand the phenomenon of its degradation, the catabolism of fatty tissue.
Lipolysis ( lipo- fatty, lysis: loosening) is “the hydrolysis of fat, resulting in a melting of adipose tissue”. This is “the initial stage of lipid catabolism. Under the action of lipases, triglycerides are hydrolyzed to fatty acids, glycerols, and partial glycerides”.
So, more simply, lipolysis is degradation, melting, loss of body fat.
This is what interests us.
Decrease in caloric intake
Fats that can be hydrolyzed, degraded, lost, come mainly from three places.
First, they come from food, from caloric intake.
Secondly, they come from the fats that are stored in the adipocytes, the fat cells.
And finally, they come from the stores stored in the muscles. However, these are only very small amounts of fat. These are not the fats we are aiming for. You surely know it, that’s what we eat that gives us energy.
And that’s what we over eat – the energy that’s contained in food, but we do not spend – that makes us gain weight. This is the main reason for excess weight: too much caloric or energy intake.
If we eat less, our organization will draw on our reserves to meet its energy needs. And it will go among another draw in fat tissue, adipocytes: lipolysis. So the first thing you can do to lose weight is to reduce your caloric intake.
